उत्तर
Given data; 16, 15, 16, 16, 8, 15, 17
Arranging the given data in ascending order, we have 8, 15, 15, 16, 16, 16, 17
a. As per the given data, 16 is the mode of data, since it has highest frequency, i.e. 3
Now, if 15 is added to the given data, mode will get changed to 15 and 16, whereas if any other number, i.e. 8, 16 or 17 is added, mode will remain same.
b. Atleast two 15’s should be added to change the mode to 15. On adding two 15’s the frequency of 15 will be maximum, i.e. 4.
c. We will have to add atleast three 17’s to change the mode to 17. On adding three 17’s, the frequency of 17 will be maximum, i.e. 4.
