Chapter 15: Two-Factor Analysis of Variance
1. a. In analysis of variance, an independent variable (or a quasi-independent variable) is
called
a factor.
b. The values of a factor that are used to create the different groups or treatment conditions
are cal
Chapter 16: Correlation
1. A positive correlation indicates that X and Y change in the same direction: As X increases, Y
also increases. A negative correlation indicates that X and Y tend to change in opposite
directions: As X increases, Y decreases.

Towards a new vision by Collins
Main points of the article are:
Our lives are framed by multiple systems of oppression
We need to understand these as not mutually exclusive categories for
analysis but as intersecting, parallel and dialectical
They can be
Chapter 18: Chi-Square Tests
1. Nonparametric tests make few if any assumptions about the populations from which the data
are obtained. For example, the populations do not need to form normal distributions, nor is it
required that different populations in
Chapter 19: The Binomial Test
1. H0: p(home team win) = .50 (no preference). The critical boundaries are z = 1.96. With
X = 42, = 32, and = 4, we obtain z = 2.50. Reject H0 and conclude that there is a significant
difference. Home teams win significantly
Chapter 14: Repeated-Measures and Two-Factor ANOVA
1. For an independent measures design, the variability within treatments is the appropriate
error term. For repeated measures, however, you must subtract out variability due to individual
differences from
Chapter 13: Introduction to Analysis of Variance
1. When there is no treatment effect, the numerator and the denominator of the F-ratio are
both measuring the same sources of variability (random, unsystematic differences from
sampling error). In this case

1.
2. The best fitting line is determined by the error between the predicted Y values on the line and
the actual Y values in the data. The regression equation is determined by the line with the
smallest total squared

Statistics is the science of planning studies and experiments, obtaining data, and then organizing,
