To calculate the range of a set of numbers, you subtract the smallest number from the largest number.
First, we identify the smallest and largest scores from the provided points:
- Smallest score: 48
- Largest score: 90
Now, we can calculate the range:
\[ \text{Range} = \text{Largest score} - \text{Smallest score} = 90 - 48 = 42 \]
Therefore, the range of the Tigers basketball team's scores is 42.
