Question

I have a question about Interpreting the Shape of Data Distributions

PLEASE HELP

1.)
a20,000
b25,000
c30,000
d40,000

2.)
a A negative skew
b A positive skew
c Symmetry
d Uniformity throughout

Answer 1

1. b 25,000
2. c Symmetry

Explanation:

The first thing you notice about this distribution is its symmetry. The left side of the centerline is a mirror image of the right side of the centerline. That centerline is between the middle two bars, at price = 25000.

1. Since the distribution is symmetric, the center of it is its mean, $25,000.

2. Because of the symmetry, there is no skew in either direction. The bell-shape is not the shape of a uniform distribution (which is flat across the top). The appropriate descriptor is that the distribution exhibits symmetry.
