Summary

When implementing an intervention, scientists will compare a control group against a group that receives the intervention. Various statistical analyses can help demonstrate whether the groups are significantly different or similar. In this project we will be comparing two data sets by determining several statistics for each of the data sets.

Project Objectives

This project will further student understanding of the following MATLAB concepts:

$$ Using MATLAB Docs $$ usage of $.$mat files

$$ output statements $$ math and stats functions

$$ the ttest function $$ assignment statements

$$ arrays $$ colon operator

$$ multiple return values

Project Implementation

Part $1$: Importing the $.$mat Variables

The project's $.$mat file has two variables in it$,$ data and N$1.$ N$1$ is the size of the control group, and data is in a single array containing numerical data collected from both the control and the experimental groups.

Complete this step by importing the "Project$2\_$PresetVariables.mat" file for use in the remainder of your program. A second file Project$2\_$PresetVariables$\_3.$mat is provided for your testing. The expected output from the two files is shown in Part $5$ below. You should perform your own testing in addition to testing with the provided examples.
