AA histogram
BThe pie chart
CScatter plot
DThe box plot
Answer & Solution
Correct answer: C. Scatter plot
1. Before fitting anything, you look at the two variables together.
2. Before taking up the discussion of linear regression and correlation, we need to examine a way to display the relation between two variables x and y.
3. That display is the scatter plot.
4. Box plots, histograms and pie charts each show one variable at a time.
