Not necessarily.
For instance, one can calculate a so-called 't' statistic as a way of testing an hypothesis about one or two population means. Notice that in this case the statistic does not describe a population characteristic.
a summary measure that is computed to describe a characteristic of an entire population is called:
this is false... a parameter is a measure of a mean or mode, a measurable characteristic of a sample is called a statistic.

A statistic is a summary measure of some characteristic of a population. If you were to take repeated samples from the population you would not get the same statistic each time - it would vary. And the set of values you would get is its sampling distribution.

In general when you take a sample of values of a random variable you will find that those values lie around some central value that is characteristic of the total population for the random variable. A measure of central tendancy (such as a sample mean, sample mode or sample median) is a statistic which is intended to estimate the central value of the population using the values in the sample in some way.
which measure best describes the data set
The test statistic is a measure of how close the sample proportion is to the null value.
The amplitude of a wave describes the greatest distance a wave vibrates from its resting position. It is the measure of the height or intensity of the wave.
A numerical value used as a summary measure for a population of data is called a statistic. It helps to describe or understand the data more easily by providing a single value that represents the entire dataset.
