Question

A comic-strip writer churns out a different number of comic strips each day. For 16 days, the writer logged the number of comic strips written each day (sorted low to high): {1, 1, 2, 2, 2, 3, 3, 3, 3, 4, 4, 4, 5, 5, 6, 7}. What type of skew can be observed in this distribution?
positive skew


negative skew


zero skew


skew cannot be observed

Answer 1

First we need to graph the given values.

there are total 16 data so x-value can be taken as 1,2,3,...,16

given values will be assigned as y-values as shown in attached table.

Now we just graph those points to see the type of skew.

From graph we see that points are very close and almost in the shape of a line. Lines seems to be moving upward when going to the right side.

Hence correct answer will be "positive skew".
