Question

plz help me in finding the mode

Answer 1

the maximum class frequency is 30, and the class corresponding to this frequency is 36 – 48. So, the modal class is 38 - 48.

Now use the mode formula.
$mode = l + \bigg( \frac{f_1-f_0}{2f_1-f_0-f_2} \bigg) \times h \\ \\ mode = 36+ \bigg( \frac{30 - 25}{2 \times 30 - 25 - 15} \bigg) \times 12 \\ \\ mode = 36+ \bigg( \frac{5}{20} \bigg) \times 12 \\ \\ mode = 36+3 \\ \\ mode = 39$

the maximum class frequency is 30, and the class corresponding to this

frequency is 36 – 48. So, the modal class is 38 - 48.
