Mode of grouped continuous data for JEE
Measures of dispersion; calculation of mean, median, mode of grouped and ungrouped data
Formula
\(\text{Mode}=l+\left(\frac{f_1-f_0}{2f_1-f_0-f_2}\right)h\)
Variables: \(l\): lower boundary of modal class, \(h\): class width, \(f_1\): frequency of modal class, \(f_0\): frequency of class preceding modal class, \(f_2\): frequency of class succeeding modal class.
Conditions: Modal class is class with maximum frequency.
Mode from grouped frequency distribution.
