How to Create a Scatter Plot: 1. Plot each point on the graph, using the values as coordinate points. 2. Draw a line through the points, which shows the general directions of the points. The line should go as much through the middle of all the points as is possible. This is called the line of best fit.

How to create a box-and-whisker plot: To draw a box-and-whisker plot you need five pieces of information, called the five-number summary: the smallest value, the lower quartile (LQ), the median, the upper quartile (U0) and the largest value. An outlier is a value that is much smaller or much larger than the other values. An outlier is a point less than the LQ-1.5x 1QR or greater than the UQ+1.5xIQR.
