The two ways of representing the data—dot plots and a scatter plot—differ in the following ways:

1. Dot Plots:

   • The dot plots show the individual distributions of hours slept and test scores separately.
   • They allow you to see how frequently each value appears in the dataset but do not show the relationship between the two variables.

2. Scatter Plot:

   • The scatter plot displays the relationship between the two variables (hours slept and test scores) in a single graph.
   • Each point represents a student, making it possible to see trends, such as whether more sleep leads to higher test scores.

In summary, dot plots focus on individual distributions, while a scatter plot shows the correlation between the two variables.

Tip:

If you want to analyze the relationship more precisely, you can calculate the correlation coefficient (r-value) to measure the strength and direction of the relationship! 🚀
