Step-by-step explanation:
Total number of values =50
Range = Highest value − Lowest value
=98−8=90
Let us divide the given data into 10 classes.
∴ Length of the Class interval =
Number of class interval
Range= 100-90
=10
The frequency table of the marks obtained by 50 students in a mathematics test is as follows.
