Engagement Activity: Probability and Samples - The Distributionof Sample Means
Samples are variable. If you take two (or three) separate samples from the same population, the samples will be different from one another because they will contain different individuals, attributes, and sample means. As a result, using different samples to predict population parameters will result in different estimates of those parameters.
For example, the following image shows a population of 100 people. The population has been stratified for ethnicity and gender based on data from the US Census Bureau 2010 for the United States.

5. Interpretation of a chi-square test for goodness of fit Suppose you are reading a study conducted in the year 2000 about welfare recipients in the United States. The study consisted of a random sample of 199 welfare recipients, and provides summary statistics about various demographic characteristics of the sample, indluding household size broken down into five categories (one, two, three, four, and five or more persons in the household). You wonder if welfare recipients tend to live in different-...
6. Engagement Activity: The t Test for Two Related Samples
6. Engagement Activity: The t Test for Two Related Samples In the last chapter, you were introduced to Professor Ken Bonanno's Statistical Methods in Psychology class, where students are asked to complete a research study as a part of the semester-long course. Many of his students' research questions could be asked using the independent-measures t test, but there are other approaches, which will be explored in this chapter. Click the following topics to see some sample questions asked by Professor Bonanno's students....
