There will be a demonstration to test the overall test of means among the five groups & test whether the amputee & hearing group is different from the crutches & wheelchair groups.

- Case Study 6.2: Preexisting preferences of fish (13:00)
- This is an analysis of case study 6.2 (Preexisting Preferences of fish). In this video, it will go over the basic outline of design. This is an experiment to test sexual selection by females. A.L. Basolo had the idea that female southern platy fish have a preference for sexual displays even in species which do not have tails designed for sexual displays. The experiment will have six pairs of males surgically given plastic sword tails but one of each of the 6 pairs were given a bright yellow tail and the other with a transparent tail.

**Chapter 7: Simple linear regression: a model for the mean **

- Case Study 7.1: The Big Bang - An observational study (12:21)
- This video will cover regression analysis using the case study 7.1 data (The Big Bang - An observational study). You will need to open this data with SPSS, data consist of resection velocity as the X variable & distance as the Y variable/ response variable. Also, it will show you how to do scatter plots for the data.

In this video, you would just work with the data which consist of variables: brain weight, body weight, gestation length, litter size. Also, consist of log transform variables: In (brain weight), In (body weight), In (litter size), & In (gestation length). Then create a scatter plot matrix to view each set of variables.

This video will give a demonstration on how to analyze the following relationships of students interactive scatter plot where we have initial height as explanatory variable & horizontal distance (punti) as the response variable. The main questions to think about is: 1. in analyzing these data, is it adequate to use a linear fit or a smoother fit through the data? 2. can you explain it with a quadratic fit or does it require a cubic fit?

- Case Study 10.02 (34:15)
- The analysis of case study 10.02 (The energy cost of echo location by bats, an observational study), the questions to keep in mind is: 1. are the energy expenditures of echo locating bats greater than the non echo locating bats for the given body weight? 2. Are those expenditures different from that the non echo locating bats different from non echo locating birds?

- This will be an analysis of case study 16.1 (Sites of short long-term memory, a controlled experiment, the book analyzes this data by doing two independent samples T test to see if there is a difference between short term memory between control and treatment groups & long term memory between control and treatment groups. Then after you see if they correlate with each other; you can do a multivariate test to find out either of those test are significant.
