Differentiate between class limits and true class limits.Give examples
Lets go through the following example to understand about class limits and true class limits.
The class marks of a distribution are 47, 52, 57, 62, 67, 72.
Since the class marks are uniformly spread.
Therefore the class size is the difference between any two consecutive class marks.
the lower limit of the first class=
the upper limit of the first class=
Therefore the first class interval=49.5-44.5=5
Similarly we can find the class limits of all the class marks given.
|class marks||class limits|
So the true class limits are same as the class limits
