The sample described is a **convenience sample**. This type of sampling involves selecting individuals who are easily accessible or readily available, rather than using random sampling methods to ensure a representative group. In this case, the sports columnist is gathering opinions from people who happen to be in a bar, which may not represent the broader population of basketball fans or stakeholders.

The sample described is a **cluster sample**. In cluster sampling, the population is divided into groups (or clusters), and then entire clusters are randomly selected for inclusion in the sample. Here, the researcher randomly selects 5 local fast food restaurants (the clusters) and then surveys all school-age children at those selected restaurants. This method allows the researcher to gather information from a specific subset of the population based on the clusters chosen.
