some stats, up-to-date as of 129 voters in the poll (1:35am EST, 7/30)
I took the values and put them into the stats/list editor on my TI89. Here are some screen grabs:
The list, frequency values in List1 and average age values for each age category in List2:
Then some statistics on the information:
the first value (x 'bar') is the average, 25.37. For the >45 category we have to guess an average age of voters over 45. Changing this value from 45-60 only creates a range of 0.93 years, I assume because there aren't enough older people to severely throw the data.
The value that looks like ox (10.0579) is the standard deviation. This is affected by changing the guess of the oldest average age. Assuming 45 it is 9.346, while assuming 60 it is 11.726.
