What is the definition of single random sampling?

• A method where all individuals have an equal chance of being selected

• A method that only selects individuals from a specific group

• A method that guarantees a representative sample

• A method that uses biased selection

Multiple Choice

What are the advantages of single random sampling?

• High representation

• Complex technique

• Time-consuming

• Requires a list of units

Multiple Choice

A teacher wants to know the average time spent doing homework by the students in her class of 20 girls and 5 boys.

She picks the student in every 5th seat.

• Simple Random

• Systematic

• voluntary response

• convenience

Multiple Choice

What are the advantages of systematic sampling?

• Quick and easy to implement

• Sample is representative and diverse

• No need to know the exact number of the population

• All of the above

Multiple Choice

What is the purpose of stratified random sampling as described in the image?

• To divide the population into distinct groups

• To select a sample randomly from the entire population

• To ensure representation from each subgroup

• To eliminate bias in sampling

Multiple Choice

What are the four steps involved in stratified random sampling as illustrated in the image?

• Population

• Strata

• Random Selection

• Sample

Multiple Choice

What are the advantages of stratified random sampling?

• High representation for each stratum

• Easier data collection

• Lower cost compared to simple random sampling

• More accurate results

Multiple Choice

What is the process of selecting random clusters in cluster sampling?

• Choosing individuals randomly

• Selecting entire clusters randomly

• Sampling from a single cluster

• Using systematic sampling

Multiple Choice

What are the steps involved in cluster sampling?

• Define the population

• Cluster the population

• Randomly select clusters

• Collect data from clusters
