Descriptive statistics involves analyzing and summarizing data, such as calculating measures of central tendency (such as the mean, in this case) and measures of variability. Calculating the average value of 5 sample measurements is an example of descriptive statistics. Hypothesis testing involves making inferences about a population based on sample data, regression analysis involves analyzing the relationship between variables, and design of experiments involves planning and conducting controlled experiments to test hypotheses.
