Histograms

Number of Flowers – 1213 – 1718 – 2223 – 2728 – 32 Height (in centimeters) Flower Heights The x-axis label shows the groups of data. Above, the groups are flower heights in centimeters. Reading a Histogram: The x-axis shows the range for each group. Above, the range for each group is 5 centimeters. The y-axis label describes the scale. Above, the scale shows the number of flowers. The y-axis shows the scale. Above, the scale is 0 to 12 flowers in intervals of 2.

Interpret Histograms How many flowers have heights above 22 centimeters? How many flowers are between 13 and 22 centimeters high? How many flowers are above 17 centimeters and below 28 centimeters? How many flowers are less than 18 centimeters high? Number of Flowers – 1213 – 1718 – 2223 – 2728 – 32 Height (in centimeters) Flower Heights
