Linear regression is one of the essential tools in statistical analysis. In this course, we'll walk through stepbystep how to conduct many important analyses using SPSS.
Although you will learn the basics of what these statistics are, we'll avoid complicated mathematical discussions and go right to what you need to know to conduct these analyses.
Linear regression is basically a tool that allows you to test relationships between many variables at the same time, control for variables' effects, and create simple statistical models that allow you to make predictions.
In this course, we'll cover the following key topics:
You'll not only learn how to conduct these analyses, we'll also go over how to interpret the statistical results and how to graph the results using SPSS and a special Excel template I've created for you.
As a bonus, we also learn how to use a new free addon to SPSS called "PROCESS," which simplifies a lot of the steps in doing interaction analysis in regression.
This course is meant to get you started in analyzing data using linear regression in SPSS. Whether you have data of your own that need to understand or you just want to know more about statistical data analysis, you'll get a running head start with this simple, easytofollow course.
I do linear regression analysis all the time in SPSS to conduct research in psychology, so I've become familiar with the steps it takes to pull off these analyses. I'm confident you will be able to, too!

Section 1: Introduction  

Lecture 1  03:17  
In this quick introductory video, I'll give you a quick preview of what's to come in the rest of this course. 

Lecture 2  Article  
Before we move forward, you'll find the sample data file in this lesson. 

Lecture 3  04:03  
In this video, we'll walk through the example data file that we'll be using in this course. You can download this file in the supplementary resources in the next lecture. 

Section 2: Correlations  
Lecture 4  04:07  
We introduce the concept of the correlation coefficient as a simple way of considering the relationships between two variables. 

Lecture 5  02:23  
Let's quickly walk stepbystep through the process of running a correlation analysis in SPSS. 

Section 3: Simple Linear Regression  
Lecture 6  06:58  
In this video, I'll expand on what a regression analysis is and why it offers more than a simple correlation. We'll cover what the regression equation is and how you could use it to make predictions from a sample dataset. 

Lecture 7  04:10  
Let's quickly walk stepbystep through the process of running a simple regression analysis in SPSS. 

Lecture 8  02:33  
In order to visualize the results of your regression analysis, you might be interested in graphing your results. This lesson will walk you through one simple way to do that in SPSS. 

Section 4: Multiple Regression Analysis  
Lecture 9  06:53  
Usually, we turn to regression analysis because we want to deal with multiple predictors at the same time. This is the kind of analysis you'd run to control for other variables. 

Lecture 10  03:21  
Let's quickly walk stepbystep through the process of running a multiple regression analysis in SPSS. 

Lecture 11  05:45  
I thought this would be a good place to stop for a moment and discuss the idea that regression analysis is all about creating a statistical model for your data. With that comes the need to assess the quality of your model, and we'll go through a few key indices of model fit. 

Section 5: Hierarchical Multiple Regression Analysis  
Lecture 12  04:32  
Hierarchical regression models are essentially multiple regression models broken into several steps. This offers a few key advantages, which we'll look at in this video. 

Section 6: Interactions in Regression Models  
Lecture 13  02:43  
We'll now turn to cases when you want to look at the effect of one variable that depends on the effect of another. By using an interaction analysis, you can test these hypotheses. 

Lecture 14  03:47  
Let's quickly walk stepbystep through the process of running an interaction analysis in SPSS. 

Lecture 15  Article  
See this lesson for instructions on downloading the handy Excel graphing template. 

Lecture 16  07:57  
See the supplementary resources for this lesson to download the Excel file I use in this video. It will help you easily graph an interaction. 

Section 7: Interactions Made Simple with PROCESS  
Lecture 17  01:33  
To make things easier, you can use a special addon for SPSS: "PROCESS." This is a free addon, and in this video, you'll see where you can download the materials. 

Lecture 18  03:16  
Once you've downloaded and unzipped the PROCESS files from the previous lesson, you'll need to install it in SPSS. This video shows you how. 

Lecture 19  03:37  
Now that PROCESS is installed in SPSS, let's use it to do an interaction analysis between two continuous variables. 

Lecture 20  07:16  
Time to make sense of the SPSS output! In this lesson, I'll walk you through what all of the output means. 

Lecture 21  05:19  
You can use the same Excel file from a previous lesson to graph the interaction that PROCESS supplies you with. 

Section 8: Interactions with Categorical Variables  
Lecture 22  04:37  
Until this point, we've only considered the role of continuous variables in our regression analyses. You may want to include categorical variables in your model, though. In this lesson, I'll show you how to analyze an interaction between a continuous and a categorical variable using PROCESS in SPSS. 

Lecture 23  03:48  
Once you have the output from your interaction analysis, graphing it isn't much different from the other times we've graphed an interaction. 

Section 9: Conclusion  
Lecture 24 
Conclusion & Farewell

00:53 
I am a social psychologist. My expertise is in the domain of attitudes and persuasion, but I have extensive experience with all corners of the social psychology world. The research in this field is so interesting that I can't help but want to share it! I look forward to the chance to share the world of social psychology with you.
