Math Graphs

Histogram Histograms are used to display data using a horizontal or vertical rectangular bar that levels off at the appropriate level. Histograms are very similar to bar graphs except that the bars are connected and show a block of time or measurement. This bar graph shows how long children stayed in the swimming pool on a hot afternoon.

During which time period was the trail the most crowded? The least crowded? 7 P.M. – 10 P.M.; 1 P.M. – 4 P.M. Can you tell how many cyclists were on the trail at 5:00 P.M.? Explain. No; the histogram shows data for intervals of time, not individual times. On another day, 3 more cyclists were on the trail at 8 A.M., 5 fewer were on at 2:00 P.M., and 10 more were on at 5:30 P.M. How would the histogram for this day be different? The 7 A.M. – 10 A.M. bar would go up to 58; The 1 P.M. – 4 P.M. bar would go down to 20 and the 4 P.M. – 7 P.M. bar would go up to 70.

Draw your own Histogram Here is the information for your histogram. The local amusement park had visitors all day long on Saturday. From 10:00 – 12:00 100 visitors were at the park, from 12:00 – 2:00, 300 visitors were at the park, from 2:00 – 4:00 450 visitors were at the park, from 4:00 – 6:00, 350 visitors were at the park, and from 6:00 – 8:00, 200 visitors were at the park. Dont forget a title for your graph. Remember to label!
