You supervise a YouTube channel that focuses on reviews for movies and television shows. You look at 5 different ways viewers reach your videos. You want to find out if there are better avenues for viewers to find your videos compared to others. You look at your 10 strongest videos and looked at the amount of views over the past day based on how viewers found the videos. Construct a One Way ANOVA to test if there are differences in average views for each avenue for finding videos.
