Questions: A facilities supervisor at a sports stadium wants to rate the condition of the seats at the stadium. Which of the following best describes a convenience sample of seats? The supervisor uses a computer program to draw 56 seats at random and selects these seats. Every set of 56 seats is equally likely to be drawn by the computer program. All of the seats in the VIP section are easily accessible. So, the supervisor selects the 56 seats in this section. The supervisor forms groups of 8 seats based on the sections the seats are in. Then, she selects all of the seats in 7 randomly chosen groups.

Solution

Solution Steps

Step 1: Understanding Stratified Sampling

Stratified sampling involves dividing the students into strata based on numbers of classes. Each stratum is then sampled randomly, ensuring that the sample size is proportional to the stratum's size in the population or as specified by the study design.

Step 2: Implementation

This would require identifying distinct groups within the students based on numbers of classes and then performing random sampling within each group to select a total of 25 members.

Final Answer:

The sampling method best described by the given scenario is ^Stratified Sampling^.

Step 1: Understanding Convenience Sampling

Convenience sampling selects members of the seats at the stadium that are easiest to access. This method does not ensure randomness and is subject to bias, making it not representative of the entire seats at the stadium.

Step 2: Implementation

This method would involve selecting 56 members from the seats at the stadium based on ease of access, without attempting to randomize the selection process.

Final Answer:

The sampling method best described by the given scenario is ^Convenience Sampling^.

Step 1: Understanding Cluster Sampling

Cluster sampling involves dividing the seats into clusters based on sections and then randomly selecting entire clusters. All members of the chosen clusters are included in the sample.

Step 2: Implementation

This would involve identifying clusters within the seats based on sections and then randomly selecting clusters until the sample includes 56 members.

Final Answer:

The sampling method best described by the given scenario is ^Cluster Sampling^.
