Question

when a trend line is drawn on a scatterplot, there are 4 points above the trend line. about how many points should be below the trend line?
○ 0
○ 2
○ 4
○ 8

Explanation:

Step1: Understand the trend line purpose

A trend line in a scatterplot is drawn to show the general direction of the data. It should be balanced, meaning the number of points above and below (excluding those on the line) should be approximately equal for a good fit.

Step2: Apply the balance concept

Given there are 4 points above the trend line, for the trend line to represent the data's trend well, the number of points below should be about the same as above. So it should be around 4.

Answer:

4 (corresponding to the option "4")
