I want to create a scatter plot that shows the average SAT score over time in the U.S. I have a data frame (named "df") that has two variables, "averageSAT" and "year", with a single observation for each year. I use the following code to create this plot. Why would the plot generated from this be confusing? Ineed to group_by the data first There will be too many observations for a scatter plot to be informative There is no issue with this code. The generated plot will clearly present the data Year should be the horizontal axis variable and averageSAT the vertical axis variable
