Math 217 Final Project
Introduction Background Health care and how it should be delivered are perennial topics in the political life of the United States. In discussing this topic, there are a great deal of anecdotal examples thrown around in support of or in opposition to our current system, a government-provided health insurance system, or a state-provided (universa...

Lab for Weeks 11 and 12, Math 217
Introduction to linear regression Batter up The movie Moneyball focuses on the “quest for the secret of success in baseball”. It follows a low-budget team, the Oakland Athletics, who believed that underused statistics, such as a player’s ability to get on base, better predict the ability to score runs than typical statistics like home runs...

Lab on Confidence Intervals
Foundations for statistical inference - Confidence intervals Sampling from Ames, Iowa If you have access to data on an entire population, say the size of every house in Ames, Iowa, it’s straight forward to answer questions like, “How big is the typical house in Ames?” and “How much variation is there in sizes of houses?”. If you have a...

Lab 5 Math 217
Foundations for statistical inference - Sampling distributions In this lab, we will investigate the ways in which the statistics from a random sample of data can serve as point estimates for population parameters. We’re interested in formulating a sampling distribution of our estimate in order to learn about the properties of the estimate, such...

Inference for numerical data North Carolina births In 2004, the state of North Carolina released a large data set containing information on births recorded in this state. This data set is useful to researchers studying the relation between habits and practices of expectant mothers and the birth of their children. We will work with a random sampl...

Lab on Inference for Categorical Variables
Inference for categorical data In August of 2012, news outlets ranging from the Washington Post to the Huffington Post ran a story about the rise of atheism in America. The source for the story was a poll that asked people, “Irrespective of whether you attend a place of worship or not, would you say you are a religious person, not a religious p...

Multiple Linear Regression
Multiple Linear Regression Grading the Professor Many college courses conclude by giving students the opportunity to evaluate the course and the instructor anonymously. However, the use of these student evaluations as an indicator of course quality and teaching effectiveness is often criticized because these measures may reflect the influence of...
