which line is the best model for the data in the scatter plot?
Answer
Explanation:
Step1: Recall best - fit line concept
The best - fit line for a scatter - plot is the line that minimizes the sum of the squared vertical distances between the data points and the line.
Step2: Visually assess the lines
Visually, the line that passes as close as possible to most of the data points is the best model. A good best - fit line should have data points evenly distributed above and below it.
Step3: Analyze the options
By looking at the scatter - plots, we need to find the line that has the least overall deviation from the data points.
Answer:
Without specific labels for the lines in the scatter - plots, it's not possible to give a definite answer. But in general, choose the line that has data points evenly scattered around it with the least overall distance from the points.
