AGRC1023 Lecture Notes - Lecture 12: Khan Academy, Null Hypothesis, Working Hypothesis
Document Summary
Comparing many means (one way anova, lsd testing of means) o o o. How many factors answer is always 1. That single factor has multiple levels, but only one factor in this course. Least significance testing of means anova says: it"s significant , but doesn"t tell us what difference need to find out what specifically is not the same: lsd. Examining the relationship between 2 continuous measurements (linear regression) o o o. We can group, put things in boxes to determine. Here, we"re looking at two continuous measurements, so not putting in different boxes we have two scales, not totally separated any more. Always put assumptions on a4 taking in hardest to remember. Working hypothesis: i think if we do x, y will happen. Null hypothesis is always quite simple o o. Stated null hypothesis examples: u1 = 0, b = 0, u1 = u2.
