Question

Statistics help please?

Answer 1

@ganeshie8 i think the answer is the second picture (C) but i just wanted to get a second opinion, thanks!

Answer 2

C looks good !

Answer 3

ok thanks, i was debating between C and E because it seemed that both the first and second pictures in E had clusters but wasn't positive

Answer 4

i dont see clusters in first distribution in option E
i could be wrong though... im just guessing

Answer 5

oh ok i saw one cluster in the first distribution in E 3rd and 5th from the left

Answer 6

what is a cluster exactly ?

Answer 7

im asking as i dont seem to find a satisficatory definition online..

Answer 8

This is what my textbook says but i don't know if that really helps at all: Distributions can have several other characteristics, like gaps, clusters, and outliers. Gaps in a distribution happen where there is a significant number of values with no observations. Clusters are groups of observations at similar values.

Answer 9

Okay then we're right option C has to be the only one with clusters

we don't have clusters in first distribution in option E as it is skewed right... as there is a tail on right end and most data vales are on the left end

Answer 10

ok thanks!
