 STA2023 Elementary Statistics
 If you change the way you look at things, the things you look at change. Max Plank Any fool can know. The point is to understand. Albert Einstein STA2023 Statistics Lectures are limited to main concepts and solving examples. Most of the time, we will be solving problems in class. In every class.  The use of a graphing calculator is strongly recommended: Casio 9750, TI 84 or similar. Taken from the "Insider s guide to teaching with the Triola Statistics Series" by Mario Triola, author of the textbook: The author s personal preference is to require that each student have a TI 83 plus or TI 84 plus calculator, and each student also do several software projects using Statdisk.

Normal dist on Casio9750GII Central Limit Theorem: Regardless of the population distribution model, as the sample size increases, the sample mean tends to be normally distributed around the population mean. T-Distribution: The t distribution, also known as Student t-distribution, is a probability distribution that is used to estimate population parameters when the sample size is small and when the population variance is unknown. 02/18, 02/20: Confidence intervals or intervals estimate: Estimating a Population proportion and a Population mean.
