Statistics and Graphs II

Make Bar Graphs

Henry displayed the data at the

right in a horizontal bar graph.

To make a horizontal bar graph:


Draw horizontal and vertical axes

on grid paper.

Use the data from the table to choose

an appropriate scale. (The data range

from 26 to 82. Choose intervals of 10.)

Draw and label the scale along the

horizontal axis. Start at 0 and

label equal intervals.

Label the vertical axis. List

the name of each dinosaur.

Draw horizontal bars to

represent each length.

Make the bars of equal

width.

Write a title for your graph.

To make a vertical bar graph, place the scale along the

vertical axis and the items along the horizontal axis.

Solve.Use the bar graph above.

1. What data are along the vertical 2. Which dinosaurs have lengths
   axis? the horizontal axis? between 30 and 40 feet?


2. Make a horizontal or vertical bar graph using the data
   on lengths of dinosaurs. Change the scale to represent
   20-ft intervals.

Albertosaurus 26 ft

Allosaurus 36 ft

Brachiosaurus 52 ft

Tyrannosaurus 39 ft

Ultrasaurus 82 ft
