Sampling techniques describes the different ways in which a certain portion of the population can be selected to represent the entire population. Hence, the solution to the questions are ;

  • Sample
  • Parameter
  • Systematic Sampling.

A sample describes a subset of the population which is usually selected randomly to represent the population data. Hence, the first 10 and last 50 runners are the sample.

Statistical values which are obtained from the population data are called parameters. While those calculated from the sample data are called Statistic. Hence, since the measure is obtained from the population data, then it is a Parameter.

A sampling technique whereby samples are selected randomly at fixed intervals is called systematic sampling. Here, every 5th person is a fixed sampling interval. Hence, it is a systematic sampling procedure.
