Observe the data and answer the questions that follow:
16, 15, 16, 16, 8, 15, 17
A. Which data value can be put in the data so that the mode remains the same?
B. At least how many and which value(s) must be put in to change the mode to 15?
C. What is the least number of data values that must be put in to change the mode to 17? Name them.
Answer :
(A) Mode = the term which is repeated maximum in data
The given data is
16, 15, 16, 16, 8, 15, 17
As the mode is 16 ∵ (it is repeated 6 times in data)
∴ Adding 16 to data mode will remain the same
(B) as 15 is 2 times in the data
we need to add 15 in data 2 times
So that 15 become most repeated term(4 times)
(C) As 17 is only 1 times in data
We need to add 3 more !7 in the data to make mode of the data to be 17
