Question

There is a set of 100 observations with a mean of 40 and a standard deviation of 0. What is the value of the smallest observation in the set?

Answer 1

a standard deviation of 0 means that all the values are the same ...

Answer 2

in other words; none of the values deviate from the mean :)

Answer 3

so if i can figure out that one number then i have my answer?

Answer 4

Answer 5

Answer 6

Answer 7

that is caveman talk :)

if the mean of all the observations is 40; and there is no deviation among the samples ... then the lowest value has to be 40
