Consider the variable, type of birth control practiced (
e.
g., an iud, condoms, none, etc). which measure of variability is best suited to describe variation in the distribution of this variable?

ian gonna lie that is way to much

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have

answer4 to the second power is 16

and 4 to the third power is 64,
