Question

which step comes last when using the divide - center method to find the trend line on a scatterplot?
approximate the center of the cluster located on the left side of the line, and repeat for the right side of the line.
connect the two centers to produce the trend line.
disregard all outliers.
draw a vertical line so that each side has the same number of data points.

Explanation:

Step1: Understand the divide - center method steps

The divide - center method for finding a trend line on a scatterplot has the following general steps:

1. First, disregard all outliers (to focus on the main data cluster).
2. Then, draw a vertical line so that each side has the same number of data points (dividing the data).
3. Next, approximate the center of the cluster on the left side of the line and do the same for the right side (finding representative points for each half).
4. Finally, connect the two centers to produce the trend line.

Answer:

Connect the two centers to produce the trend line.
