Survey Analysis

Only one person answered my survey and that was Professor Richter.  I think it was very nice that he has a pet and goes to church 4 times a month.  The Mean, Median, and Standard Deviation is very easy to explain. 
      It there is only one response and the answer is one, then 1 divided by 1 is 1; 1 is the mean.  The Median is 1 because when I wrote down the responses the number 1 was the middle number.  (When writting down all of the totals in order and choose the middle number, in my case my middle number is 1).  The Standard Formula example:
Consider a population consisting of the following eight values:

These eight data points have the mean (average) of 5:

To calculate the population standard deviation, first compute the difference of each data point from the mean, and square the result of each:

Next, compute the average of these values, and take the square root:

 

My results for the standard deviation is 0.
