An expert reviews a sample of 10 scientific articles (n=10) and records the following number of errors in each article: 0, 4, 2, 8, 2, 3, 1, 0, 5 and 7. Compute the SS, the variance, and the standard deviation for this sample computational formula.

A social psychologist records the age (in years) that a sample of eight participants first experienced peer pressure. The recorded ages for the participants are 14, 20, 17, 16, 12, 16, 15, and 16. Compute the SS, the variance, and the standard deviation for this sample computational formula.
