Aschool sells boxes of cookies each year for a charity fund. the data set shows the number of boxes the 10 families living on willow avenue buy, on average, every year.
{2, 3, 2, 2, 0, 5, 2, 1, 1, 3}
does this data have negative, positive, or zero skew?

This data set has zero skew as it is symmetric.

We know that the symmetry exist in a data when the mean, median and mode of the data is same.

i.e. we are given a set of data as:

              {2, 3, 2, 2, 0, 5, 2, 1, 1, 3}

    0  1   1   2   2   2   2   3   3   5

Hence, the value that occur in the middle is: 2

Hence, we have Median=2

              Hence, Mean=2.1

Here 2 occurs most number of times i.e. 4 times and hence we have:

                   Mode=2

Now, as the Mean, Median and Mode of the data are approximately same.

      Hence, we get the data is symmetric and hence has a zero skew.

exactly you go it
