Question
Georgia and her classmates also measured their foot length. Use a pencil to find the trend line .Sketch the trend line for the scatter plot .
Hint:
A trend line is a straight line that best represents the points on a scatter plot. The trend line may go through some points but need not go through them all. The trend line is used to show the pattern of the data. This trend line may show a positive or negative trend.
We are asked to sketch the trend line for the scatter plot.
The correct answer is: We are asked to sketch the trend line for the scatter plot.
Step 1 of 1:
The data relates the height of a person to the foot length in inches. The trend line is not necessary to go through each and every point. It portrays the behavior of the data in common.
The trend line approximates the data, so the line must in middle of all the data. Ideally, half of the points will be above the line and the other half being below the line. Thus, the required line would be:
The answer can be easily found by dividing the points equally on the plane. This will help us to find the path of the line. Moreover, the trend line need not be accurate, since it gives the approximate value.
