PSYA01H3 Lecture Notes - Lecture 10: Standard Deviation, Descriptive Statistics, Big Bang
Document Summary
The lectures are a way to help you through understanding the content in the book. Active studying- you take notes while reading the book, or write a m/c question (which is a good method to maximize your study). You can also rely on the external links on portal to get some extra questions. Mode: what there is the most of in a sample. Slide 30: the first set in the example has values that are close together, but the second set has a wider range. : mean absolute deviation- you take each deviation point, subtract the mean from it, and. Deviation: -2, -1, 0, +1, +2 mean=0 takes an absolute value of that to see how far it deviates from the mean. That"s why there needs more mathematical concepts involved in variability. You remove the sign and just add up the deviation (now called absolute deviation) deviation mean=1. 2.
