Exploring Random Sampling Methods

The video tutorial covers four random sampling methods: simple random sampling, stratified random sampling, cluster random sampling, and systematic random sampling. Each method is explained with steps and examples, highlighting their unique characteristics and applications in data collection. Simple random sampling ensures unbiased selection, stratified sampling divides the population into homogeneous groups, cluster sampling involves selecting entire heterogeneous groups, and systematic sampling uses a fixed interval for selection.

Which of the following is NOT one of the four random sampling methods discussed?

• Stratified Random Sample

• Convenience Sample

• Simple Random Sample

• Cluster Random Sample

What is the main advantage of using a Simple Random Sample (SRS)?

• It is the most cost-effective method

• It ensures each individual has an equal chance of being selected

• It always provides the most accurate results

• It is the easiest method to perform

Which of the following is a step in performing Stratified Random Sampling?

• Using a system to survey people

• Grouping subjects based on the same characteristics

• Numbering the groups from 1 through N

• Surveying every participant in a selected group

In the hotel example for Stratified Random Sampling, why is each floor considered a different stratum?

• Because each floor has different types of guests

• Because each floor has different amenities

• Because each floor has a different view of the city

• Because each floor has a different number of rooms
