Regression Analysis: Definition & Examples

1. Regression Analysis: Definition & Examples

Watch this video lesson to learn about regression analysis and how you can use it to help you analyze and better understand data that you receive from surveys or observations. Learn what is involved in regression analysis and what to look out for.

Simple Linear Regression: Definition, Formula & Examples

2. Simple Linear Regression: Definition, Formula & Examples

Simple linear regression is a great way to make observations and interpret data. In this lesson, you will learn to find the regression line of a set of data using a ruler and a graphing calculator.

Problem Solving Using Linear Regression: Steps & Examples

3. Problem Solving Using Linear Regression: Steps & Examples

Linear regression can be a powerful tool for predicting and interpreting information. Learn to use two common formulas for linear regression in this lesson.

Analyzing Residuals: Process & Examples

4. Analyzing Residuals: Process & Examples

Can you tell what's normal or independent and what's not? Sometimes, we need to figure this out in the world of statistics. This lesson shows you how as it explains residuals and regression assumptions in the context of linear regression analysis.

Using Regression Analysis in Business

5. Using Regression Analysis in Business

Statistical analyses and models, like regression analysis, can be extremely helpful when businesses need to forecast their financials and product demand. In this lesson, we'll learn how regression analysis can help accomplish these goals.

Multiple Regression Analysis in Business: Uses & Examples

6. Multiple Regression Analysis in Business: Uses & Examples

Regression analysis is a powerful statistical tool that can help remove variables that do not matter and select those that do. This lesson explores the use of a regression analysis to answer research questions in business.

How to Create a Multiple Regression Analysis

7. How to Create a Multiple Regression Analysis

A multiple regression analysis is a statistical method that's used to compare the effects of multiple independent variables on a single dependent variable. Care must be taken when setting up the input data, and when analyzing the individual results.

Categorical Variables in Regression Analysis

8. Categorical Variables in Regression Analysis

A categorical variable is one that takes on non-numeric values such as gender or race. In this lesson, we look at coding of categorical variables using dummy numeric variables so that this data can be used in regression analysis.
