Find the sample variance s2 for the following sample data. Round your answer to the nearest hundredth.
x:
23
17
12
35
29

Find the mean first, then subtract the mean from each score and square each difference. Sum those differences and divide by n to get the variance.
By the way, "^" is used online to indicate an exponent, e.g., x^2 = x squared.
