# Expert Answers

1) Given the raw Quiz Scores organize Scores, create a frequency Distribution Chart, then Calculate the ∑X, Mean (µ), Median, Mode, and N.

5 4 5 3 6 1 3 2 5 4

6 2 4 5 6 4 3 4 6 2

Show your work for calculating each M (mean, median, & mode):

2) Given the raw Quiz Scores Organize the Scores Calculate the ∑X, N, the Mean (µ), Deviation Scores (X-µ), Deviation Scores Squared (X-µ)2, the Sum of the Squares (SS), Variance (σ2 = SS/N), Standard Deviation (σ = √SS/N). Then find Variance (s2=SS/n-1) and Standard Deviation (s=√SS/n-1) if this were a sample group.
