• the spread between the smallest and the largest numbers in a range of numbers
1.
Work in groups of three or four. To the nearest centimetre, measure and record the height of each member of your group.
2.
Record the results for the entire class on the board. Include the height and gender of each student.
3.
Decide on an interval , and then organize the data into groups. You may wish to use 10 cm as the interval for the height of students in your class. Round the shortest height down to the nearest 10 cm.
For example, if the shortest height is 122 cm, start the first interval at 120 cm. Develop a frequency table using the model below.
Interval
120 to 129 cm
130 to 139 cm

How does the type of graph you used affect the amount and the type of information it displays?
b) List advantages and disadvantages of the type of graph you used.
5. a)
6.
Separate the data into two categories. For example, you might compare boys and girls.
