4/22 -- LAMC High School: Samples & Sampling Distributions: how do we get data to tell us about populations? -- Prof. Johanna Hardin (Pomona College)
In this session we will explore different ways of sampling from populations. How is it done poorly, and how can we do it well? We'll talk about recent polls that give us some ideas for predicting the upcoming presidential election.
Additionally, we'll talk about sampling distributions -- a sampling distribution tells us what to expect for our sample under certain constraints. Information from the sampling distribution allows us to test a research claim or to come up with specific methodology. We will use examples to illustrate the ideas.
