Question

# The following is the formula for finding the mode of grouped data. State what p  and q are. Mode=p+q−f0(q−f0)+(q−f2)×h

A
p = l, lower limit of modal class; q=f1, frequency of modal class
B
p = l, middle value of modal class; q=f1, frequency of modal class
C
p = l, size of class interval; q=f1, frequency of modal class
D
p = l, slope; q=f1, frequency of lower class

Solution

## The correct option is A p = l, lower limit of modal class; q=f1, frequency of modal classThe formula for mode is given by, Mode=l+f1−f0(f1−f0)+(f1−f2)×h,where, l = lower limit of modal class h = size of class interval f1 = frequency of modal class f0 = frequency of class preceding modal class f2 = frequency of class succeeding modal class So, p = l = lower limit of modal class And, q = f1 = frequency of modal class.
