Question

in a study, the sample is chosen by pulling 50 names from a hat

what is the sampling method?

• simple random
• stratified
• convenience
• none of these

Explanation:

⚡ Using what you learned: Sampling Methods

Step 1: Analyze the selection process

The study selects a sample of \( 50 \) names by pulling them directly from a hat.

Step 2: Match with sampling definitions

• Simple Random Sampling: Every member of the population has an equal chance of being selected, and every possible sample of size \( n \) has an equal chance of selection (like drawing names from a well-mixed hat).
• Stratified Sampling: The population is divided into subgroups (strata), and random samples are taken from each subgroup.
• Convenience Sampling: Selection is based on ease of access rather than random selection.

Drawing names out of a hat is a classic physical demonstration of a Simple Random sampling method.

Answer:

Simple Random
