Question

Students at one middle school are called to lunch by their grade level. To determine whether all students at the school liked to eat hamburgers, hotdogs, or pizza for lunch, the lunchroom manager surveyed the first 30 students that were in the lunchroom. What type of sample is this? Please Help

Answer 1

The sample used by the lunchroom manager is a convenience sample.

Step-by-step explanation:

The type of sample that the lunchroom manager used is called a convenience sample. A convenience sample is a non-probability sampling technique where the researcher selects participants based on their easy accessibility and proximity to the researcher. In this case, the lunchroom manager surveyed the first 30 students who were in the lunchroom without using any specific criteria or random selection.

Answer 2

Cluster Sample

Step-by-step explanation:

According to ThoughtCo., "A cluster sample involves using a simple random sample of evident groups that the population contains." Since only the first students that enter the cafeteria are surveyed, not all grade levels are included. Since most schools do lunch by grade, only a certain grade would get to have a say, so there could be some bias.

(Edit: Looking back on this it might could be a convenience sample but it depends on what the answer choices are)
