I'm having trouble with one of the statistics interview questions from this resource. The question is:

Given a data set X, calculate the mean and variance of X.

I've tried to solve the problem using the following code:

But when I run the code, I get an error. Can anyone help me figure out what the problem is? Any help would be greatly appreciated. Thanks!

Given a data set X, calculate the mean and variance of X.

I've tried to solve the problem using the following code:

Code:

`mean = 0`

for i in range(len(X)):

mean += X[i]

mean = mean/len(X)

variance = 0

for i in range(len(X)):

variance += (X[i]-mean)**2

variance = variance/len(X)

But when I run the code, I get an error. Can anyone help me figure out what the problem is? Any help would be greatly appreciated. Thanks!
