Terminology in Grouped Mode Formula

Terminology in Grouped Mode Formula

$$Z=l+\left(\frac{f_1-f_0}{2f_1-f_0-f_2}\right)h$$

where:

$$l$$ = lower boundary of modal class

$$f_1$$ = frequency of modal class

$$f_0$$ = frequency of class preceding modal class

$$f_2$$ = frequency of class succeeding modal class

$$h$$ = class width

Usage

- Used to correctly substitute values in the grouped-data mode formula.
