Question

the class marks of classes in a distribution are 104,114,124,134,144,154,164.find class size and upper limit of first class​

Answer 1

Answer:

Class size =10

As class size is the difference between upper limit and lower limit

EX : 114−104

Class size = 10

Class limit : the lowest and highest marks which are included in a class are called lower class limit and upper class limits of the class.

Ex : 104−114

lower class limit is 104 and upper class limit = 114

Hence, this is the answer.
