On Demand: Running Regressions and ANCOVAs in SPSS GLM

 



The No-Tears Guide to Running Regressions and ANCOVAs in SPSS

 


 

Confusing.
Terrible.
Frustrating.

These are just a few of the adjectives researchers use to describe the process of trying to run linear regressions and ANCOVAs in SPSS. And it’s true – the vocabulary and menu options that SPSS uses for these processes are NOT user-friendly.

But… you don’t have to be frustrated and confused. You don’t have to waste time, trying to figure out how to get SPSS to do what you want it to do. You CAN master SPSS for Regressions and ANCOVAS.

Reduce frustration…
Reduce errors…
Increase your confidence with…

 

Running Regressions and ANCOVAs
in SPSS


A 3-Hour Online Tutorial

 

 

 


“[This course] is one of the easiest and most friendly ways of explaining regression to non-statisticians that I have ever followed. Very useful.”

Karen Grace-MartinI’m Karen Grace Martin, your tutorial instructor for Running Regressions and ANCOVAs in SPSS.

My goal is that by the end of the tutorial, you will understand the ins and outs of SPSS’s General Linear Model and Linear Regression procedures. You’ll have a much better understanding of how SPSS handles linear models, as well as the defaults and when to change them, and which options are appropriate for which analyses.

In this three-hour online tutorial, you’ll improve your understanding of Regression and ANCOVA and how they fit into the overall General Linear Model framework.

 


 

Who Is This Tutorial For?

 

This tutorial is for you if:

  • You’ve used SPSS’s General Linear Model procedure and are confused by all the options. You wish you really understood what they mean, whether or not you should use them, and why.
  • You run all your regression models in the Linear Regression procedure, but spend hours creating dummy variables or interaction terms. You’ve heard that General Linear Model can do this for you, but you don’t understand the difference.
  • You’re working on, or will soon begin, analyses for a research project that involves linear regression, ANOVA, or ANCOVA. (You’ll learn how to do it before you even start, and save hours, or even days of time).
  • You’re an experienced SPSS user, but you would love to go back and really understand what everything means.
  • You’re pretty comfortable with SPSS menus, but haven’t used Syntax much and would love to learn how the menus correspond to the Syntax.

 

 


 

How Does It Work?

 

This course is a 3-hour online tutorial.

The tutorial and accompanying materials are already available for you to access on your private tutorial website. Log in at any time from any internet-enabled computer, phone, or tablet… all from your own home or office.

In the tutorial videos, the instructor will present concepts and explain the meaning of the statistical models , then demonstrate how to translate those models to SPSS. We will go step-by-step through all the various buttons, menus, and options of SPSS to make sure you GET IT.

 


 

As a participant in the Running Regressions and ANCOVAs in SPSS tutorial, you’ll have access to a participant-only website, your tutorial “hub.” That’s where you’ll access all tutorial resources and material, including:

  • A set of streaming training videos.

    Watch (and re-watch) these videos on YOUR schedule, as many times as you like, at the speed you desire.

    These videos explain the concepts and steps as well as step-by-step demonstrations in SPSS.

  • Supplemental PDF handouts.

    You’ll have access to the presentation slides, handy checklists, and worksheets to help you set up your next power calculation. You can download, print out, and take notes as you follow along.

  • Data files from actual research studies.

    So you can see how to deal with the challenges inherent in real data.

  • Exercises to practice what you’ve learned.

    With answers to check your work.

  • A place to submit written questions.

    Got a question as you’re reviewing the video recording or your notes? Just submit a question in the tutorial website. We’ll answer it right there.

  • Bonus videos.

    To enhance your understanding of linear models, we’ve included the following bonus video webinars:

Dummy Coding and Effect Coding in Regression Models (60-minute video presentation)
Getting Started with SPSS Syntax (60-minute video presentation)
Correlated Predictors in Regression Models: Detecting Multicollinearity (60-minute video presentation)

You’ll have access to this site and all the related materials and resources for ONE FULL YEAR. That means you can re-watch sessions and ask additional questions any time during that 12-month period.

Often, our students report they understand the material at a deeper level on a second or third pass. This stuff is not always easy. You’ll learn more every time, so take advantage of it!

What’s Covered in the Tutorial?

 

The tutorial material is broken into three modules, which are available immediately via the tutorial website.

Module 1: Univariate GLM Overview

The 5 boxes:

  • Dependent Variable
  • Fixed Factors
  • Random Factors
  • Covariates
  • WLS Weight
  • What you put into each one, when, and the defaults and language in SPSS

The Options Button:

  • Which of the 10 Display options are relevant to which GLM analyses.
  • The definition, meaning and situations to use each option.

The Model Button:

  • The defaults in SPSS for interaction terms, how and when to override them, and how the order in which you build terms affects the meaning of the output.
  • Type I and Type III Sums of Squares–what they are, what they mean, and when to use each one.

The Save Button:

  • Saving Predicted Values, Residuals, and Diagnostics to test assumptions
  • Syntax: Using Syntax is usually more efficient than the menus, has more options, and gives you an audit trail of what you’ve done. We will talk about how to use the Paste button to create syntax, then how to modify it, and the basic logical structure of the Univariate GLM syntax.

Module 2: Linear Regression Demonstration

I’ll demonstrate a multiple regression analysis with a dummy-coded categorical predictor first without, then with, an interaction. You’ll see how the choices you need to make and the output changes by including the dummy variable and the interaction.

We will go through the 5 boxes, the Options, Model, and Save in the specific context of a Linear Regression model.

We’ll specifically run this example in both the Linear Regression and General Linear Model procedures to see the differences in options, defaults, and possible output.

Module 3: Analysis of Variance and Analysis of Covariance Demonstration

We’ll run an ANOVA with two categorical factors and a continuous covariate. You’ll see how adding the covariate requires different options and output to interpret, and the similarities and differences between this analysis and the multiple regression.

This module will specifically cover sections of the SPSS GLM that are only relevant for ANOVAs and ANCOVAs:

  • Estimated Marginal Means–what they are, what they mean, and when you need them
  • The Plots Button: Profile Plots–how to do them, why to do them, and what they mean
  • The Post-Hoc Button:
    — How and when to perform a post-hoc test
    — How to read the results and what they mean
    — Which Post-hoc tests you should never use, and when to use Tukey, Bonferroni, and Dunnett
  • The Contrasts Button: Definitions for each of the Contrasts, changing the reference group, and seeing how to do and interpret a Simple Contrast

About Your Instructor

 

I’m Karen Grace-Martin, your instructor.

As president and founder of The Analysis Factor, I’ve been supporting researchers like you through their statistical planning, analysis, and interpretation since 1997.

With masters degrees in both applied statistics and social psychology, I’ve been honored over the past 15 years to work with everyone from undergrad honors students to Cornell professors, and from non-profit evaluators to corporate data analysts.

After seeing so many smart people get nervous, uncertain, and downright phobic about analyzing their data, I made it my mission to remove the barrier between research and statistical analysis.

I want to banish the “stats speak” that makes eyes glaze over, and instead explain statistical terminology in plain English.

My goal is to help you improve your statistical literacy so you can bring your important research results into the light with confidence.
