find the mode of the following data height above 30 above 40 above 50 above 60 above 70 above 80 no of plants 34 30 27 19 8 2
Answers
Solution:
Class Interval Number of Plants(F1) 2 3
30-40 34 83
40-50 30 64
50-60 27
60-70 19 46
70-80 8
80- above 2 10 29
-------------------------------------------------------------------------------------------------------
Analysis table: we will put a sign(A) in front of each column having highest frequency.if two or more frequency adds up to give highest frequency,we will put same sign front of each interval.
Class interval I II III Total
30-40 A A A 3
40-50 A A 2
50-60 A 1
60-70 0
70-80 0
80-above 0
Modal class=30-40
As there is no frequency behind the modal class.
Drawn the histogram of the data given.Got the modal class. =30-40
Drawn two lines one behind from the modal class and another which is successor of modal class.
Then drawn perpendicular from their point of intersection.
So, Mode = A number between 37 and 38, may be 37. aaa .......(approx)
