Range is the difference between the highest and lowest values of the given observations.
Here,
Maximum marks obtained = 100
Minimum marks obtained = 46
∴ Range of the data = Maximum marks obtained − Minimum marks obtained = 100 − 46 = 54
Thus, the range of the data is 54.
The marks obtained by 17 students in a Mathematics test (out of 100) are given below:
91, 82, 100, 100, 96, 65, 82, 76, 79, 90, 46, 64, 72, 68, 66, 48, 49.
The range of the data is ___54____.
