Descriptive statistics branch in statistics deals with the representation of the data using distinct brief coefficients. These coefficients are used as either the representative of the sample or the population.

The descriptive statistics branch is divided into two sub branches:

Measure of central tendency
Measure of dispersion.

The three measures of central tendency are:

Mean (or Average)
Median
Mode.

The measures of dispersion are:

Variance
Standard deviation
Range
Kurtosis
Skewness

The education researcher computes the average number of hours student study at various local colleges.

The average of a data is the mean value which is the measure of central tendency.

Thus, the researcher is using descriptive statistical method to summarize the data.
