Sampling Techniques and Experimental Design

Front

What is a Census?

Back

A Census is the examination of the entire population instead of a subgroup.

Front

What is Cluster Sampling?

Back

Cluster Sampling is a technique where the population is divided into groups (clusters) and a sample is taken from one or more of these clusters.

Front

True or False: All samples lead to a good prediction about an entire population.

Back

False

Front

What is Stratified Random Sampling?

Back

Stratified Random Sampling is a method where the population is divided into subgroups (strata) and samples are taken from each stratum.

Front

What is Convenience Sampling?

Back

Convenience Sampling is a non-probability sampling technique where samples are taken from a group that is easily accessible.

Front

What is Simple Random Sampling?

Back

Simple Random Sampling is a method where every member of the population has an equal chance of being selected.

Front

What is the purpose of Sampling Techniques?

Back

Sampling Techniques are used to select a subset of individuals from a population to estimate characteristics of the whole population.

Front

What is Bias in Sampling?

Back

Bias in Sampling refers to systematic errors that lead to an unrepresentative sample.

Front

What is the difference between a Sample and a Population?

Back

A Sample is a subset of a population, while a Population includes all members of a specified group.

Front

What is Systematic Sampling?

Back

Systematic Sampling is a method where samples are selected at regular intervals from a sorted list.
