Answer 1

The sampling method used in this study is stratified sampling. The population is divided into distinct groups called strata, and the coach selects players from each age group to form the soccer team.

Step-by-step explanation:

The sampling method used in this study is stratified sampling.

In a stratified sample, the population is divided into distinct groups called strata. In this case, the different age groups of boys (eight to ten, eleven to twelve, and thirteen to fourteen) are the strata.

The soccer coach selects a specific number of players from each age group to form a recreational soccer team, ensuring representation from all age groups. This method allows for a more precise representation of each age group in the sample.
