Comparing Metric Variables

Summary This tutorial shows how to create proper tables and means charts for multiple metric variables. If statistical assumptions are satisfied, these may be followed up by a repeated measures ANOVA. We’ll use income 2010 through income_2014 from freelancers.sav throughout this tutorial. SPSS FREQUENCIES for Inspecting Histograms We’ll first inspect the data in income_2010 through income_2014 by running basic histograms. This […]

Association between Metric Variables

Summary This tutorial will investigate the association between metric variables with nice tables and charts. As an example, we’ll use income_2010 and income_2011 from freelancers.sav. Quick Data Check Before jumping into analyses, let’s first just inspect whether both variables have plausible values. A fast way for doing so is generating a histogram by running FREQUENCIES. The syntax below does just that. […]

Association between Metric and Categorical Variable

Summary This tutorial shows how to run nice tables and graphs for investigating the association between a metric and a categorical variable. If statistical assumptions are met, these may be followed up by an ANOVA. As an example, we’ll use freelancers.sav and see whether (and how) sector_2010 is related to income_2010. Data Inspection and FILTER We’ll first inspect FREQUENCIES for sector_2010 by running the syntax below […]

Association between Metric and Dichotomous Variable

Summary This tutorial shows how to create nice tables and charts for studying the association between a dichotomous and a metric variable. If statistical assumptions are met, these may be followed up by an independent samples t test. As an example, we’ll investigate whether there’s an association between income_2010 and gender in freelancers.sav: is the average income over 2010 equal for […]

Association between Categorical Variables

This tutorial walks through running nice tables and charts for investigating the association between categorical or dichotomous variables. If statistical assumptions are met, these may be followed up by a chi-square test. As an example, we’ll see whether sector_2010 and sector_2011 in freelancers.sav are associated in any way. SPSS Quick Data Check Before doing anything else, let’s first just take a quick […]
