You can put this solution on YOUR website! Find the variance for the given data. Round your answer to one more decimal place than the original data.
{-2, -2, 11, -7, 3}
1st: Find the mean of the data.
2nd: Subtract the mean from each of the data values.
3rd: Square each of those differences
4th: Divide by n-1 = 5
---
That is the variance:
variance = 46.2
