This tutorial uses a subset of real data collected by the Enduring Love project. This research sought to establish the factors that affect the longevity of people's relationships, and investigated how enduring relationships are experienced by couples at different generational points in their life course. The data was collected using a questionnaire, which included a measure of how happy participants were with their relationship/partner. In this example we are only interested in one aspect of this project: whether people in different age groups experience their relationships differently.

Age : The Age column represents our independent variable. Codes have been used to tell SPSS which condition each of the participants belonged to. In this case:

1 = Young adults (under 35 years of age) 2 = Middle-aged adults (aged 35-55) 3 = Older adults (aged over 55)

Happiness_Score : This column displays each participant's happiness score. As part of this study, participants filled out a questionnaire which included a measure of how happy participants were with their relationship/partner. Their score on this measure is our DV and ranges from 1 to 5, with higher scores representing greater happiness with their partner and relationship.

Does age have an effect on perceived happiness in relationships? Run a complete ANOVA and give a full APA write-up of the results.

The data can be retried using this code chunk:
