Ground beef was on sale today so we stocked up with 20 pounds. Divided it into ziploc half pound portions, flatten and freeze them .

Husband just talked to a friend online and she said "oh yeah, we saw that sale and stocked up too!" Apparently she freezes portions the same way!

(And to refute some of the guys on this forum who have posited that women are "spendypants", these were all women.  Mind you, their spouses are on board with this sensible spending.)

Are you sure? I think mustachian women might actually be somewhat more common than men. All anecdotally derived statements wrong or your money back, of course.

I assume that everyone I come across online is a man, but in fairness, I know there are definitely a few mustachian ladies out there. It's just a different set of temptations for them than there are for men. They're told that they must spend money on clothing and makeup, we're told we must spend money on sportscars and I don't know/care what else.

Sorry in advance, I am going to totally derail this mini-thread.

Lots of us probably have gender neutral names - I do.

So GrayGhost, why do you assume everyone you come across online is a man?  There are lots of women (clearly identified as such) posting on the journal group.

When I am on Ravelry I assume the odds are high (but definitely not 100%) that a gender-neutral name is a female poster, but there are men there too.  However it is a site about an activity that tends to be engaged in more by women.  Finance is gender neutral.  0r to be more realistic, since on average women live longer than men, we should be more interested in our financial futures, not less, than men are.  So should I assume that most people on here, not clearly identified as men, are women?  Especially since my gut feeling is that women are more likely to be ambiguous about gender identificaiton on an open forum?

I assume that everyone I come across online is a man, but in fairness, I know there are definitely a few mustachian ladies out there. It's just a different set of temptations for them than there are for men. They're told that they must spend money on clothing and makeup, we're told we must spend money on sportscars and I don't know/care what else.

On Wednesday, I contacted our 401k plan administrator and found out that the mega Backdoor Roth is a valid option at my company. My coworker overheard, leading to an in depth discussion on how this changed the game since he and his wife also max out their 401ks. He got excited when he read the Mad FIentist article and was going to bring the article home to discuss strategy with his wife.

He also talked about how he was excited that his 8 year old son could get a job when he hit 16 just so he could help him start a Roth.

So, from 355 votes (and I think males vote less on that) you say that the majority of of 14682 total members is male?
Get a statistics class please ;)
(On that a sidenote: NEVER trust a poll where you dont know the excact question and how they did it. Depeding on the wording of the question alone you can get 91% for and 92% against something.)

On the topic of assumptions: Most forums have male dominance. Males do more internet, too.

Actually for a survey that actually may hit statistical significance. But you'd have to account for self-selection and I don't have the stats on the difference between men and women in filling out online surveys.

I spoke few days ago with one of the trainees (a student basically) we have at work about the expense of living here and was really impressed that he manages to live just fine on about 1,000$ a month. Just for a perspective the equivalent would be living in NYC or San Francisco on 20k. May apartment alone costs 1,600….

A coworker from a different location told me today that he plans to retire between 30 and 35. He hasn't exactly figured out how to do it yet, but he is saving a good deal of his pay check to do so. I excitedly told him that I was doing this too. I then told him about index funds and that I was currently doing some tax reduction planning. He said that he would look at MMM and look into index funds.

I haven't ever gotten along with the guy, but maybe things will change now.

On the topic of assumptions: Most forums have male dominance. Males do more internet, too.

Running a quick Chi square test with an assumed 50/50 distribution, we get a two-tailed P=0.064, which is barely not enough to reject the null hypothesis that there are as many men as women on this forum (P>0.05). A bigger N actually may have pushed it over to prove that there are more women than men here.

It of course does not assume any selection bias, but I wouldn't be too concerned about the phrasing of a question of gender, since it's not an ambiguous question (as opposed to "are you for or against" type questions). I would not assume that most people on this forum are men.

.064 hints very, very strongly, more strongly than other stuff that has been acted upon before.

.064 is not statistically significant.  All it hints is that we may be able to get significance if we increase the N large enough.  However, for a survey over 300 is normally enough unless their is bias, which I don't know.

.05 is a pretty arbitrary cutoff. I think in this instance we don't need to have any more confidence to call the race, assuming of course like you say there isn't any bias we are missing. It's not like we actually need to be right, anyway. If anything of significance was riding on this I would call for more testing, but meh.

Yes, it is but it is a cut off determined by researchers in human research for many years.  Unless we get there I am going to stick with, we don't know.

93.6% chance we're right isn't good enough? The usual cutoff of. 05 is more when you can start to mention it in a paper, not that it didn't tell you which direction you should be looking.

This is not what the p value means. From Wikipedia (if you don't trust Wikipedia, I'm sure I could find a better source with better searching).
Quote
There are several common misunderstandings about p-values.[15][16]

    The p-value is not the probability that the null hypothesis is true, nor is it the probability that the alternative hypothesis is false – it is not connected to either of these. In fact, frequentist statistics does not, and cannot, attach probabilities to hypotheses. Comparison of Bayesian and classical approaches shows that a p-value can be very close to zero while the posterior probability of the null is very close to unity (if there is no alternative hypothesis with a large enough a priori probability and which would explain the results more easily). This is Lindley's paradox. But there are also a priori probability distributions where the posterior probability and the p-value have similar or equal values.[17]
    The p-value is not the probability that a finding is "merely a fluke." Calculating the p-value is based on the assumption that every finding is a fluke, that is, the product of chance alone. Thus, the probability that the result is due to chance is in fact unity. The phrase "the results are due to chance" is used to mean that the null hypothesis is probably correct. However, that is merely a restatement of the inverse probability fallacy, since the p-value cannot be used to figure out the probability of a hypothesis being true.
    The p-value is not the probability of falsely rejecting the null hypothesis. This error is a version of the so-called prosecutor's fallacy.
    The p-value is not the probability that replicating the experiment would yield the same conclusion. Quantifying the replicability of an experiment was attempted through the concept of p-rep.
    The significance level, such as 0.05, is not determined by the p-value. Rather, the significance level is decided by the person conducting the experiment (with the value 0.05 widely used by the scientific community) before the data are viewed, and is compared against the calculated p-value after the test has been performed. (However, reporting a p-value is more useful than simply saying that the results were or were not significant at a given level, and allows readers to decide for themselves whether to consider the results significant.)
    The p-value does not indicate the size or importance of the observed effect. The two do vary together however–the larger the effect, the smaller sample size will be required to get a significant p-value (see effect size).

This forum is majority female:
http://forum.mrmoneymustache.com/welcome-to-the-forum/what-gender-are-you/
So, from 355 votes (and I think males vote less on that) you say that the majority of of 14682 total members is male?
Get a statistics class please ;)
(On that a sidenote: NEVER trust a poll where you dont know the excact question and how they did it. Depeding on the wording of the question alone you can get 91% for and 92% against something.)

On the topic of assumptions: Most forums have male dominance. Males do more internet, too.

Running a quick Chi square test with an assumed 50/50 distribution, we get a two-tailed P=0.064, which is barely not enough to reject the null hypothesis that there are as many men as women on this forum (P>0.05). A bigger N actually may have pushed it over to prove that there are more women than men here.

It of course does not assume any selection bias, but I wouldn't be too concerned about the phrasing of a question of gender, since it's not an ambiguous question (as opposed to "are you for or against" type questions). I would not assume that most people on this forum are men.

.064 hints very, very strongly, more strongly than other stuff that has been acted upon before.
.064 is not statistically significant.  All it hints is that we may be able to get significance if we increase the N large enough.  However, for a survey over 300 is normally enough unless their is bias, which I don't know.

.05 is a pretty arbitrary cutoff. I think in this instance we don't need to have any more confidence to call the race, assuming of course like you say there isn't any bias we are missing. It's not like we actually need to be right, anyway. If anything of significance was riding on this I would call for more testing, but meh.
Yes, it is but it is a cut off determined by researchers in human research for many years.  Unless we get there I am going to stick with, we don't know.

93.6% chance we're right isn't good enough? The usual cutoff of. 05 is more when you can start to mention it in a paper, not that it didn't tell you which direction you should be looking.

Given that the initial hypothesis was that there are significantly more men than women on the forum, which later was argued against using the survey data (and stating that there are more women than men), I'd say that the survey results do disprove that there are more men than women on the forum at the very least. Yay surveys!

Also, it made me glad to see that there are many other women on this forum - yes, there are women who are anti-mustachian with additional expenses like makeup, jewelry, and clothes, but there are many who aren't that way!

I like makeup (expensive kind), jewelry and clothes.  However, I like time more than makeup so only use it when dressing up/presenting and because it is a good quality, it lasts.  I get giving most of my jewelry and what I buy is normally used.  And clothes, well that is used or gifted normally as well.  Just because people like those items does not mean they cannot be mustachian.

Or we could take a Bayesian approach to the problem.  Let's say there are two people:  Blue believes that most internet forums are generally evenly distributed, and Red believes that forums are typically about 70% male, with <10% of forums having 50% or more women.  These are just beliefs that two people have accumulated through experience, and without any other information, it makes sense for Red and Blue to make similar assumptions about this forum.  Now we've got some data, through the survey, and Bayes' rule tells each person how to update their beliefs about this forum with the given data.



For both Red and Blue, the additional data now lead them both to believe that there are likely more women than men in this forum.  The outcomes are slightly different, since they had different starting beliefs, but 355 people is a lot of people, so the data are definitely dominating the outcome.  Maybe someone can help me add in assumptions about women being more likely to answer the poll.

There's a famous joke about this..  If you don't believe a small random sample can work, then when you need to get bloodwork done, tell your doctor to take it all.  Statistics were designed precisely to help us draw inferences from small samples, and actually, 2% sampling is a huge amount compared to a lot of work being done all the time.

Something sort of on topic, because I realize I've veered way off course: today we had a going away party for a coworker during lunch, and we celebrated by everyone bringing their packed lunch and eating together in the break room.  The departing coworker brought cake.

The co worker who trained me is the most mustachian person I know.  He eats rice and beans most days for work and never eats out.  He takes the train to work, doesn't even own a car.  He paid off his mortgage on his condo years ago.  He only drinks water, never any coffee or anything like that.  He basically sends his salary home to his family in Venezuela and saves the rest.   He always inspires me to be thankful for what I have.

Colleague's status on facebook:
Our society is so obsessed with STUFF that there is an entire store built around only selling containers to put all of our STUFF in, and it makes enough money to survive in Manhattan.

Could be that in Manhattan it's not an abundance of stuff but a lack of square footage to keep it in.

For the most part, the people here are pretty mustachian. I believe that my manager is actually on this site, or has been in the past. Another guy rents an apartment with a roommate, just bought a new Honda Accord that I expect he'll keep for 15 years. Another walks to work, another makes her own laundry detergent. Obviously everyone has non-mustachian aspects to their lives as well, but I have very few anti-mustachian stories from here. Most of the ones I do have would still be considered financially sound--they'd probably fit in at the Boglehead forums.

I suspect I'm the only one putting away over 40% of my paycheck, but I wouldn't be surprised to find out that I'm not.

It's not at work, but it's at home while on vacation from work, so it counts ;)

While at my family Christmas gathering, my aunts and uncles (7 including my father) were reliving their childhood.    They were talking about how as members of a large family while times were tough, they each only got ONE present each Christmas.  In lieu of actual toys, they would cut out the people from the Sears-Roebuck catalogue. They would cut out clothes for the people, they would cut out a picture of a washing-machine to 'wash their clothes'.  They would cut out tires from cars, put them on cardboard and stick them on the side of shoe boxes.   You could tell by the gleam in their eye that they probably had just as much fun with cutouts from the catalogue  as they would have from real toys.

CW (age 50-ish): "I was talking to my friend and he's taking a loan from his 401(k).  Guess how much he has?  Only 7,000.  What an idiot."
Me (~1 year out of college): "Holy !@#$%^&*, *I* have more than that."
CW: "Yeah, I think my cat has more than that."

That cat is part of the 1%.

Pleased to hear that ^^
It moved me a lot, too.
If you like it, perhaps you will also like the "Book Girl" (bungaku shoujo) series. I just got the book 2-8 for christmas after seeing the film and reading the first book. I just adore Tohko (the book girl, who... no, thats a secret :D).

I assume that everyone I come across online is a man, but in fairness, I know there are definitely a few mustachian ladies out there. It's just a different set of temptations for them than there are for men. They're told that they must spend money on clothing and makeup, we're told we must spend money on sportscars and I don't know/care what else.


This forum is majority female:

I'm no statistician (and my grad school stats class was almost 2 decades ago), but in my engineering job, if I get 0.1, we consider it a very strong suggestion of a correlation.

P=.1?  Really?  As someone whose undergrad had a concentration in stats, that scares me.  We teach freshman year stats students that significance is .05 or less (for some fields even .01).  I am in research and if someone even did a poster with .1, I'd be rolling my eyes.  What kind of engineering do you do?

You wouldn't take this as a hint that you might be looking in the right direction? Really? "Guys, P was only .1, we have nothing here. Scrap it."

I wouldn't put it in a paper, but with a limited sample, it's a nice clue.

This forum is majority female:
http://forum.mrmoneymustache.com/welcome-to-the-forum/what-gender-are-you/
So, from 355 votes (and I think males vote less on that) you say that the majority of of 14682 total members is male?
Get a statistics class please ;)
(On that a sidenote: NEVER trust a poll where you dont know the excact question and how they did it. Depeding on the wording of the question alone you can get 91% for and 92% against something.)

On the topic of assumptions: Most forums have male dominance. Males do more internet, too.

Running a quick Chi square test with an assumed 50/50 distribution, we get a two-tailed P=0.064, which is barely not enough to reject the null hypothesis that there are as many men as women on this forum (P>0.05). A bigger N actually may have pushed it over to prove that there are more women than men here.

It of course does not assume any selection bias, but I wouldn't be too concerned about the phrasing of a question of gender, since it's not an ambiguous question (as opposed to "are you for or against" type questions). I would not assume that most people on this forum are men.

.064 hints very, very strongly, more strongly than other stuff that has been acted upon before.
.064 is not statistically significant.  All it hints is that we may be able to get significance if we increase the N large enough.  However, for a survey over 300 is normally enough unless their is bias, which I don't know.

In the interest of stopping this discussion... here is the alexa data on MMM users. (http://www.alexa.com/siteinfo/mrmoneymustache.com+)
That was interesting.

Too many quotes, cannot tell who I am responding to anymore.

Semiconductor process engineering.  Generally, we have fairly limited sample sets on our planned experiments.  A lot of our data comes from massive "in line" data sets with a lot of confounding and unknown variables.  So our data analysis is one of the two.  A small sample set of 6-10, or a very large set with a lot of unknowns.

That said, if we run an experiment with several variables (2-7, generally), and one of them comes out around 0.1 or lower, it's an indication of a correlation. In that case, we would continue with more experiments, where we would focus our attention on that variable (or those, if there are more than one that fell into that category), and attempt to hold the remaining uncorrelated variables constant.

There's a lot of noise and a lot of "unintentional" differences.
