This document provides an overview of t-tests, including the three main types: one sample t-test, independent samples t-test, and paired samples t-test. Examples and step-by-step instructions are given for conducting each type of t-test.
This document discusses t-tests, which are used to test hypotheses about single means or differences between two means using small sample sizes. It covers: 1. Using a one-sample t-test to test if a sample mean differs from a hypothesized population mean when the population standard deviation is unknown. 2.
Module 6. T-Test two sample test – measures the difference between means of two independent groups. T-test two sample test can be classified as:
Techniques that allow us to make inferences about a population based on data that we gather from a sample } Study results will vary from sample to sample strictly due to random chance (i.e., sampling error) } Inferential statistics allow us to determine how likely it is to obtain a set of results from a single sample } This is also known as ...
Topics include graphical and numerical descriptive measures, probability, common random variables and their distributions including the binomial and normal distributions, the Central Limit Theorem, sampling procedures, confidence intervals and hypothesis testing of one variable, and an introduction to correlation and simple linear regression.
