The ages of ten students of a group are given below. The ages have been recorded in years and months.
$8-6, 9-0, 8-4, 9-3, 7-8, 8-11, 8-7, 9-2, 7¬10, 8-8$
Determine the range?
The ages of the ten students can be written as:
8 years 6 months
9 years 0 months
8 years 4 months
9 years 3 months
7 years 8 months
8 years 11 months
8 years 7 months
9 years 2 months
7 years 10 months
8 years 8 months
From the given data,
Range $=$ Highest term $-$ Lowest term
$=$ 9 years 3 months $-$ 7 years 8 months
$=$ 1 year 7 months
