Question

how do you find the sample variance?

Answer 1

I know how to find the sample standard deviation, jut I need help on how to find the sample variance....

Answer 2

Is the sample variance the average, or arithmetic mean?

Answer 3

@jim_thompson5910
could you just tell me a simplified definition of a sample variance really quickly?
sorry

Answer 4

if you know the sample standard deviation, you square it to get the sample variance

Answer 5

sample variance = (sample standard deviation)^2

Answer 6

so do you calculate whatever you got with the
((n-mean)^2+(n-mean)^2...)/n-1
and for the sample standard deviation does it one step farther and square root it?

Answer 7

correct

Answer 8

Ok thank you so much for spending your time!
