Do It Yourself!: Building a Histogram
Histogram Demo
Table 1.11 in the text lists the number of quarts of milk purchased by 25 households for a given week. Construct a histogram of these data by clicking in the appropriate column in the applet below for each count. For example, for the first value of 0, click in the 0 column. For the next value of 3, click in the 3 column, and so on. As you move the cursor across the applet, a light gray box will show you where the next click will add a box to the histogram.Quarts of Milk Purchased
