1. How can you use a scatter plot to describe the relationship between two data sets 2. A student claims that if y-values are not increasing as x-values increase, then the data must show a negative association. Explain the error the student made.

2. In a scatter plot that shows a positive association, describe how y-values change as x-values increases.

1. Use graph paper to create a scatter plot. Draw the x- and y- axes, ensure they intersect and label the origin. Ensure that the x- and y- axes also have correct titles. Next, plot each data point within the graph. Any trends between the plotted data sets should now be evident.

the correct answer is b) histograms can be used to exhibit the shape of distributions. this is because histograms count the frequency of each possible answer, so one is able to see which results are more common and which are less common.
