Description

Want to ace the AP Statistics exam and also do well in your class? Maybe you are taking an elementary or introductory statistics course in college and need the extra help. We'll help you do it with 90 lessons, including several hours of illustrated lecture video, several worked-out example questions, and a complete understanding of the graphing calculator and its statistical capabilities.

Each lesson also comes with a downloadable word document of course notes to help you learn the material as you watch the video lessons.

In this lesson we discuss inference procedures for categorical data. We begin with Chi Square Goodness of Fit tests. Actual data is compared to expected data. Both Chi Square Tests for Independence and Homogeneity are then discussed. We look at two way tables for both tests and find expected counts. The Chi Square Test Statistic is studied as well as the conditions for Chi Square Inference. Examples of Hypothesis Tests are given.

In this lesson, we look at linear regression inference with the construction of both confidence intervals and hypothesis tests. The conditions for inference are addressed. We look at the standard error component and summarized statistical values found in tables. Regression concepts are revisted.

Welcome!

I am excited to impart knowledge for your entry level statistics and AP statistics courses.

I am a graduate of the University of Nebraska where I earned my bachelors degree in Mathematics and Actuarial Science. I furthered my education in Texas and earned my Masters of Science degree in Statistics from the University of Houston Clear Lake.

My first career began in Galveston, Texas where I worked as an actuary for American National Insurance Company from January 1985 – August 1992. After eight years in the actuarial profession I decided to turn my efforts toward teaching. I taught the next eight years at two different public schools in the Houston area. After eight years of instruction, I switched my career path back to the actuarial field. I moved to Omaha, Nebraska for two years and worked with Central States Health and Life Company as a valuation actuary. My family and I returned to Texas where I continued the actuarial profession, once again, for American National Insurance Company in Galveston for the next three years. I currently teach AP Statistics and college math courses for a school in the Houston area.

I am excited to bring the classroom to you. I have always had a passion to teach and enjoy it very much. I hope you find the videos both educational and helpful!
Sincerely,

Jerry Linch
