The video is the first of a three-part series. Here, we examine the first part of chapter 3 in the Measurement and Evaluation in Human Performance book (5th Ed.). I use the term "context" a lot in this chapter.

The objectives include terms, math, Scales of Measurement, and Summation Notation. I have all the raw material recorded for the whole chapter but felt I needed to end this at 15 or so minutes.

Answers:
Example 1:
1, 2, 2, 3, 3
(EX)^2= 121
EX^2 = 27

Example 2:
3, 1, 2, 2, 4, 5, 1, 4, 3, 5
EX= 30
EX^2= 110
(EX)^2= 900
n= 10
S^2= 2.22
