Question

The figures below display three density curves, each with three points marked on them. At which of these points on each curve do the mean and the median fall? Match your answers below for each curve.

Step 1:

Density Curve (a).

Enter the number of the term that corresponds to each choice:

Mean.

Median.

Medians divide the area into two equal halves. The mean is the balance point of the distribution. Remember from Chapter 2 what a skew (long tail) does to the mean.

Step 2:

Density Curve (b).

Enter the number of the term that corresponds to each choice:

Mean.

Median.

This is a symmetric density curve. If folded in half, it will exactly overlay itself. Where are the mean and median in symmetric distributions?

Step 3:

Density Curve (c).

Enter the number of the term that corresponds to each choice:

Mean.

Median.

Explanation / Answer

1) mean 3

median 2

2) median 2

mean 2

3)mean 2

median 1
