Explain how to draw a trend line for a scatterplot using the divide-center of data method.

Before you can draw a trend line in your data, you should have a given data at hand. And then draw the trend line or line of best fit.

1. Plot your data in a graphing paper or excel.
2. Make sure that your plotted data has a solid mark to indicate the points in the graph.
3. Divide your data points by labeling x at the center, at the farthest part of your line (left or right diagonally).
4. If you feel that the data are now finely divided, then construct a line base on the x marks you're placing
5. Then you will notice how far or near your date points are by simply looking at the points near the constructed line that you created.
