given {x,y,z} and if the first data set term is 3, what is the third term?

1. the data set range is 0 (zero)
2. the date set standard deviation is 0 (zero)

The answer given is B. However, I don't understand why 1 alone is not sufficient :shock: . Can someone explain it to me? Thank you in advance.

I would agree D should be the answer
If range is 0, then all 3 terms should be 3

I agree with the OA answer B
If the set is (3,0,-3) the range is zero, so the std dev post would be the only correct ans.

for {3,0,-3} the range is not zero of course

It is largest - smallest = 3 - (-3) = 6

if range =0 then largest = smallest= 3 .


So the answer is D

Range is the difference between the highest and the lowest terms.

in ur example, it is not zero.It is 6

Range would be 6 in your example. Agree Largest - Smallest = Range
