Archaeologists often find only parts of ancient human remains. For example, they may find a small finger bone, called the metacarpal bone. Is it possible to predict the height of a human from the length of his or her metacarpal bone? To investigate, a researcher measures the heights and metacarpal lengths of 200 adults. In making the scatterplot, the researcher should

A.
plot the height of the person on the horizontal axis.
B.
plot the metacarpal length on the horizontal axis.
C.
first determine if the heights of humans follow a Normal distribution.
D.
use a plotting scale that makes the overall trend roughly linear.

Is the answer B?

Yes, the answer is B. In this scenario, the researcher wants to investigate the relationship between the length of the metacarpal bone and the height of a human. To create a scatterplot, the researcher should plot the metacarpal length on the horizontal axis and the height of the person on the vertical axis. This way, they can visually examine the data and observe any potential patterns or trends between the two variables.

To make a prediction, it doesn't matter which variable is measured on the abscissa.

So B is not the correct answer?

Is the answer C?
