I’m trying to solve task #7 in the A/B Testing project:
This is my code:
clicks_by_experiment <- ads_clicked %>% group_by(experimental_group, ad_clicked) %>% summarize(count = n()) clicks_by_experiment
However, when I save I receive two errors:
Error in group_by(., experimental_group, ad_clicked): object 'ads_clicked' not found
Error in eval(expr, envir, enclos): object 'clicks_by_experiment' not found
Can someone help me understand what I am doing wrong?
