In sampling, the share of the population described by a statistic is called the what?

The share of the population described by a statistic is called a proportion. A proportion measures the part of the whole that has a particular attribute, computed as the number with the attribute divided by the total population. It ranges from 0 to 1 (or 0% to 100% when shown as a percent). In sampling, the estimate of the population proportion is denoted p-hat and is calculated as the count with the attribute in the sample divided by the sample size. A percentage is just the same idea expressed as a percent, a fraction is another way to write the same idea, and a ratio could compare parts to each other rather than to the whole—so it isn’t the standard term for the share of the population.
