Question

Which is a positively skewed distribution

Answer 1

Option C is the answer.

Explanation:

We will try to understand the behavior of each graph given in options.

A). In this graph bars show the symmetry on both the sides of the highest bar. Therefore, the graph represents a symmetric graph.

B). In this graph most of the points have been plotted on the left side of the maximum data value and has a long tale on the left side. Therefore the graph is negatively skewed graph.

C). In this graph most of the points have been plotted on the right side of the maximum valued data. Hence it has a tale on the right side. Therefore, The given graph is positively skewed.

D). This graph has the equal tails on each side of the maximum value. Therefore represents a symmetric graph.

Option C is the correct option.

Answer 2

Choice C

Explanation:

A and B represent symmetric distributions, that is most data values lie in the middle and the both tails are equally longer.

C represents a positively skewed distribution, most of the data values lie to the left with a few points skewing the shape of the distribution to the right.
