Mean and Standard Deviation of a Discrete Random Variable Probability Distribution
08262016 03:55 AM
Hi,
Can comeone please help me with calculating the the mean and standard deviation of the following discrete random variable probability distribution.
*k = 0.14
I would like the mean and standard deviation of the number of people per car.
I have used the 'Statistics 1 VAR App' and I have entered the following:
When I click 'Stats' the following appears:
The answers (rounded to two decimal places) for the mean and standard deviation should be:
Mean = 3.67
Standard Deviation = 1.31
It seems that the statistical calculations are based on the 'D1' column only.
Can someone please show me how I can set the statistical calculations to include the data of columns 'D1' and 'D2'?
Thanks,
Arthur

I have solved my own problem.
