Question

Hii friends

plz tell me

what is the formula of mode and median

Answer 1

Here is your answer ⤵ ⤵⤵⤵⤵⤵

Formula for ,

Mode = l+ F1-F0/2F1-F0-F2 x h

l = lower limit of the modal class.
f1 = frequency of the modal class.
f0= frequency of the class preceding the modal class.
f2 = frequency of the class succeeding the modal class.
h = size of the modal class.

Median -

l+{n/2-cf/f} x h

l = lower limit of the median class.
n = no of observation.
f = frequency of the median class.
cf = Cumulative frequency of the median class.




HOPE IT HELPS YOU ☺☺ !!!

Answer 2

Mean Add all the data elements and divide the sum by number of data elements. What you get is Mean.

Median Arrange all the data elements in ascending order. The data element placed exactly at the mid point is Median.

A problem may come if the number of data elements is even. In that case, take the average of the two middle values. That becomes Median.

Mode is the most frequently occurring data element in the data set.

Note that a data set may not necessarily have a Mode. If each data element is occurring only once, there will be no Mode.

On the other hand, if two or three data elements are repeating themselves, the same number of times; there will be two or three Modes.

hope it helps
