<em>Sample Answer: </em><em>To draw a trend line with the divide-center method, first exclude any outliers. Draw a vertical line to divide the data cluster into two groups with approximately the same number of points. Find the center of each group and connect those centers to form the trend line.</em>
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.
