![]() ![]() First, we introduce the example we have used in this guide. The purpose of this guide is to show you how to create a simple scatterplot using SPSS Statistics. A simple scatterplot could also be used to determine if there is a linear relationship between the distance women can run in 30 minutes and their VO 2max, which is a measure of fitness (i.e., your dependent variable would be "distance run" and your independent variable would be "VO 2max"). Note: If you are analysing your data using an ANCOVA (analysis of covariance) or two-way ANOVA, for example, you will need to consider a grouped scatterplot instead (N.B., if you need help creating a grouped scatterplot using SPSS Statistics, we show you how in our enhanced content).įor example, a simple scatterplot could be used to determine if there is a linear relationship between lawyers' salaries and the number of years they have practiced law (i.e., your dependent variable would be "salary" and your independent variable would be "years practicing law"). ![]() For example, determining whether a relationship is linear (or not) is an important assumption if you are analysing your data using Pearson's product-moment correlation, Spearman's rank-order correlation, simple linear regression, multiple regression, amongst other statistical tests. ![]() A Simple Scatterplot using SPSS Statistics IntroductionĪ simple scatterplot can be used to (a) determine whether a relationship is linear, (b) detect outliers and (c) graphically present a relationship between two continuous variables. ![]()
