Guided Project: Visualizing Earnings Based On College Majors - Scatter Plot Inferences?

What inferences were drawn from the scatter plots and how? I don’t see any inferences in the solution provided.

Thanks in advance.


Yeah I have the same question…
Also, which column determins the popularity of a major? is it by rank?
Final question, I didn’t fully understand the the (“Sample_size”) column represent…

Thanks in advance
