Question

The class intervals for a continuous
variable are 0 - 249, 250 - 499, 500
749,750 - 999, 1000 - 1249. What is
the mid value of the second class?
O 374
O 249
O 374.5
O 375.5​

Answer 1

ANSWER

Class width is the number of points in the class interval.

class width = upper limit − lower limit

The limits are not continuous, hence they are taken as average of upper limit of preceding class and lower limit of succeeding class.

Upper limit for second class =

2

200+201

=200.5

Lower limit for second class =

2

100+101

=100.5

Class width =200.5−100.5=100
