Ch 55: Linear Regression & Correlation
About This Chapter
Linear Regression & Correlation - Chapter Summary
The resources in this chapter ensure you're able to boost your knowledge of linear regression and correlation in a manner that works best for you. Review lessons at your leisure to study the processes, formulas, steps and definitions associated with these concepts. Once you've completed this chapter, you will be prepared for the following:
- Describing the process of creating and interpreting scatterplots
- Defining and providing the formula for simple linear regression
- Explaining how to use linear regression to solve problems
- Sharing how to interpret the slope and intercept of a linear model
- Demonstrating how to interpret correlations in research results
Watch videos or review full transcripts to grasp the information covered in the lessons. Timelines are available below the videos to skip to key topics if you need to revisit concepts. Before, during or after reviewing each lesson, test your knowledge by taking a self-assessment quiz. Further gauge your comprehension by taking the broader chapter exam.
1. Creating & Interpreting Scatterplots: Process & Examples
Scatterplots are a great visual representation of two sets of data. In this lesson, you will learn how to interpret bivariate data to create scatterplots and understand the relationship between the two variables.
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.
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.
4. Interpreting the Slope & Intercept of a Linear Model
You've probably seen slope and intercept in algebra. These concepts can also be used to predict and understand information in statistics. Take a look at this lesson!
5. How to Interpret Correlations in Research Results
Perhaps the most common statistic you'll see from psychology is a correlation. Do you know how to correctly interpret correlations when you see them? This lesson covers everything you need to know.
