In the back of my mind I still think I'm 17 so this is pretty confusing for me :S

As of right now, the average age is 17.6875 I'm roughly 17.583333 years old, so I'm not too surprised at the average, but I guess I'm kind of surprised at the dispersal.. Hm, interesting. It seems like most people here are between 13 and 25, but I do wonder what the standard deviation is. I also think we need more data to get a more accurate estimate. With such a small sample size (less than 100) it would be easy for outliers to affect our numbers. But there I go again. 3 years of statistics and 2 of calculus... And I am still asking for a standard deviation....

I took the liberty of quickly running some summary statistics on our data. The excel file (xlsx) is available for download. The results were interesting. But to believe them, we have to make a few assumptions. Those assumptions are as follows: 1. There is a normal distribution to the data. 2. The survey was taken by RANDOM pogotribe members, and were not selectively taken by any specific group being measured. The first piece is important because most data taken scientifically follows a normal distribution, whether it is height, intensity of color, size of hands, or fitness. Most people are average, and as we move away from average, less and less people are in the extremes. Assuming all this, the average seems to be 17.56 and the standard deviation seems to be 3.13. Why did I take a standard deviation? It tells us how spread out the data is. Of course this is a young poll, with only 75 data points, so the more people who take the poll, the more accurate the data, but we can say that if the people answering the poll represents a truly randomized sample of pogotribe members, then the true average of pogotribe members is somewhere between 14 and 20. This means if you are between 14 and 20 years of age, you can consider yourself the average pogotribe member. IT DOES NOT MEAN THE AVERAGE POGOTRIBE MEMBER IS AROUND 17.56. In statistics saying this will be a big no no! 17.56 is he average age of all the members of pogotribe who have taken this survey but there is error in the survey. The error lies in that it is a sample, and not the entire pogotribe population. If there were other surveys taken of pogotribe members we can better predict the true average by taking a standard deviation of the means. However, this one survey cannot give us that information. What it can give us is a very interesting histogram. The first assumption has to be broken! We do not have a normal (bell curve) distribution in our data. We have a data set with what we call a trailing tail on the high end. Our data is still valid because other statistical tests show that none of the data points in this set are outliers. For example, if someone the age of 40 had taken the survey, their information would have affected the average so much, that it would not have been a true average that could represent pogotribe. What this means is, outliers make the tail too long on one end of the data, so it would be more representative of the entire population to not count them in the stats (but you can include them when giving a range) What we have here is a survey that tries to make a prediction about the greater pogotribe community. We take a few members and ask their age, but from their data we can make predictions about what other peoples age. For example, take this as a probability. If someone were to take the survey their is a 68 percent chance they would choose an answer between 1 standard deviation of the mean. So I already know something about people who have not taken the survey yet. Again this is just preliminary statistics, and we dont have enough votes in the survey to have a lot of statistical power [if I were to ask a question which required a p value, there is not enough data to give me a definitive answer (p less than or equal to .05)], but we can use it in terms of probability, like I said before. Again the excel file is here for download for anyone to use. And the Trend line I used fit the data better than a normal distribution Attachments:
