Question

explain the concepts of frequency . class limits and mid value of frequency distribution​

Answer 1

Answer:

Mid -value: It is the average of the lower limit and the upper limit of a class.Example:

Mid—value

Lower limit of the first class is 0 and the upper limit is 10. Therefore, mid-value of the first class is 0+10 / 2 i.e., 5. Similarly; other mid—values have been worked out

Answer 2

Explanation:

In a frequency distribution series, we make use of various class intervals to represent the range of values of the data under consideration. The class intervals are framed according to the lowest and maximum value of the given data. Also, these class intervals have an upper and lower value.
