Sampling Methods
Math ⇒ Statistics and Probability
Sampling Methods starts at 9 and continues till grade 12.
QuestionsToday has an evolving set of questions to continuously challenge students so that their knowledge grows in Sampling Methods.
How you perform is determined by your score and the time you take.
When you play a quiz, your answers are evaluated in concept instead of actual words and definitions used.
See sample questions for grade 9
Describe one disadvantage of convenience sampling.
Describe the main steps in conducting a simple random sample.
Explain the difference between population and sample in statistics.
Explain why a sample is used instead of a population in many studies.
A city is divided into 10 districts. A researcher randomly selects 2 districts and surveys all residents in those districts. What sampling method is this? (1) Cluster sampling (2) Stratified sampling (3) Systematic sampling (4) Convenience sampling
A population consists of 500 students. If a sample of 50 is selected using simple random sampling, what is the probability that any one student is chosen?
A population has 1000 people. If you select every 10th person from a list, how many people will be in your sample?
A researcher divides a population into regions and randomly selects some regions to survey everyone in those regions. What is this method called? (1) Stratified sampling (2) Cluster sampling (3) Systematic sampling (4) Convenience sampling

Fill in the blank: A ________ is a subset of a population selected for analysis.
Fill in the blank: In ________ sampling, every member of the population does not have a known chance of being selected.
Fill in the blank: In ________ sampling, the population is divided into groups, and a whole group is randomly selected for study.
Fill in the blank: In ________ sampling, the researcher uses their own judgment to select the sample.
True or False: A sample should always be larger than the population.
True or False: Cluster sampling is more effective when the population is spread over a large area.
True or False: Convenience sampling is a type of probability sampling.
True or False: In cluster sampling, only some members of the selected clusters are surveyed.
