Modal class = 4000 – 5000,
l = 4000,
class width (h) = 1000,
fm = 18, f1 = 4 and f2 = 9
Formula
Mode Formula:
Mode = l+ [(fm-f1)/(2fm-f1-f2)]×h
Substitute the values in the given formula
Mode = 4000+((18-4)/(36-4-9))×1000
Mode = 4000+(14000/23) = 4000+608.695
Mode = 4608.695
Mode = 4608.7 (approximately)
Answer
So, the mode of the given data is 4608.7 runs
