Modified Box Plot Help + Simple Standard Deviation
so i have 3 box plot diagrams given to me:
and i have to answer a few questions on it, without knowing what the actual raw data is:
1) Which one of the 3 distributions is most likely to have a mean that is greater than the median?
(my guess is C because the Interquartile Range is the biggest amongst the 3)
2) Which one has the smallest maximumn?
(my guess is A because B has outliers and C looks alot bigger)
3) Which one has the smallest value of Q3?
(my guess is A)
i just want someone to confirm if i'm right on these, thanks.
for Standard Deviation:
Consider a sample of 3 observations, with a standard deviation of s =2. If the smallest two observations are 10 and 12, what is the value of the third observation?
is 14 right? because it says 10 and 12 are the lesser of the 3 observations
