How do we test for moderation?
a. Look at the effect of the moderator variable in a regression in which the outcome is predicted from a predictor and the proposed moderator.
b. Look at the indirect effect of a predictor on an outcome variable via the proposed moderator.
c. Look at the reduction in the direct effect of a predictor on an outcome variable when the proposed moderator is also included.
d. Look at the interaction term in a regression in which the outcome variable is predicted from a predictor, the proposed moderator and their interaction.
Homework Answers

imagine we wanted to look a predictors of popularity of famous sports people. We might hypothesize that the type of sport played would predict how popular the sports person was. Imagine we recruited 100 participants and asked them to rate out of 10(10 = They are the best sports person in the world, 0 = They are the worst sports person in the world) how much they liked 100 famous sports people from 10 different types of sports ( 10...

Question 8, 12.1.11 Question Hop Researchers were interested in the impact of a mother's style of helping her child understand social interactions on the child's social life. These researchers arranged for 43 volunteer mothers and their 3-to 5-year-old children to be videotaped in three separate sessions, where the mothers were rated for social coaching." "responsive style," and "nonsocial teaching' depending on the session activity. The researchers had all the children answer questions about how much they liked the other children,...

We have a regression equation: I) (restricted form , ) We want to do a Ramsey-Reset test and form the alternative hypothesis that the true functional form of the regression is: II) But in our econometrics class it is said that due to the inclusion of in the alternative form (unrestricted form) we say that this regression can not be estimated and its estimators can not be found. It is said that the reason behind it is multicollinearity and by...

How does fertility affect labor supply? That is, how much does a woman's labor supply fall when she has an additional child? We would like to estimate this effect using data for married women from the 1980 U.S. Census. The data set contains information on n = 254654 married women aged 21-35 with two or more children. In particular, the variable weeksworked is equal to the number of weeks a mother has worked in 1979; morekids is a dummy variable...

How to do with TI-83 Plus? In class we examined the linear relationship between shoe size and height for females. When looking at the male data, the following statistics were computed. For shoe size, the sample mean was 11 and the sample standard deviation was 1.35. For height, the sample mean was 71.5 and the sample standard deviation was 2.8. The sample correlation between shoe size and height was found to be r = 0.64. Find the regression equation for...

The z-test 10.1 Assume that a treatment does have an effect and that the treatment effect is being evaluated with a z hypothesis test. If all factors are held constant, how is the outcome of the hypothesis test influenced by sample size? To answer this question, do the following two tests and compare the results. For both tests,...
