Answer:
The answer is scatterplot.
Step-by-step explanation:
We can say that there is a correlation between two variables when the values of one variable is associated with the values of the other variable.
So, when determining whether there is a correlation between two variables, one should use a scatterplot to explore the data visually.
Scatter plots are just like line graphs but are much more efficient in showing how much one variable is affected by another variable.
