Tiktok Track Trends

Preregistration of analyses

Analysis #1

We will analyze the relationship between song duration and popularity of TikTok tracks to understand how the duration impacts popularity. We will conduct a linear regression and look at the R-squared of the correlation, and model it using a scatter plot. We predict that the song duration of popular songs will be around 3 minutes long– as shorter songs have the struggle of creating popular sound snippets within a more confined time, and longer songs tend to bore listeners and lose their interest.

Analysis #2

After our exploratory analysis, we want to further visualize the song danceability of TikTok tracks by comparing songs through side-by-side boxplots from before and after the COVID-19 pandemic. Specifically, we will conduct a hypothesis test to determine if there is a significant difference between the mean value of danceability pre-covid and post-covid. We will be separating our data by release date of the Tiktok tracks from before March 2020 and after March 2020. We are curious about these two variables because of our own experiences during the pandemic – a feeling of restlessness and boredom during quarantine could’ve encouraged people on TikTok to create dance trends as an outlet.
