Find the value of j from the following ,given that mode = 7
Observation :- 1,4,4,7,6,8,7,j
7
The mode is the observation with the highest frequency.
Here 4 and 7 both have a frequency of 2 so for 7 to be the mode it should occur more than twice
So if j=7
The frequency of 7 is now 3 and that makes it the mode.
