Students learn that a scatter plot is a graph in which the data
is plotted as points on a coordinate grid, and note that a "best-fit
line" can be drawn to determine the trend in the data. If the x-values
increase as the y-values increase, the scat...ter plot represents a
positive correlation. If the x-values increase as the y-values
decrease, the scatter plot represents a negative correlation. If the
data is spread out so that it is not possible to draw a "best-fit
line", there is no correlation. (02:47)[more]
