Two-way Anova

A two-way anova is used when you want to compare multiple groups across multiple independent variables. To make our dataset suitable for a two-way anova, we have added a new variable called "continent". This variable indicates whether the song was produced in North America or in Europe. Note that this variable has been simulated and was not available in the original datset.

Before we continue with our analysis, let's first get our hypotheses right. Choose the most appropriate null hypothesis for a two-way Anova knowing that our independent variables are genre and continent.

Possible answers

Average song duration is the same across all genres but different for each continent
