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 12
A population consists of 1000 students. If you select every 10th student from a list, what sampling method are you using?
A researcher uses a random number generator to select 50 names from a list of 500 employees. What type of sampling is this?
A researcher wants to ensure that both males and females are equally represented in a sample of 200 students. Which sampling method should be used?
A researcher wants to study the eating habits of students in a school. She divides the students by grade and randomly selects 10 students from each grade. What sampling method is she using?

Which of the following is a disadvantage of non-probability sampling?
(1) It is time-consuming
(2) It may not represent the population well
(3) It is always more accurate
(4) It requires a sampling frame
Which of the following is a key advantage of stratified sampling?
(1) It is always easier to implement
(2) It guarantees equal sample sizes from each group
(3) It increases the precision of estimates by reducing sampling error
(4) It does not require knowledge of population characteristics
Which of the following is a limitation of cluster sampling?
(1) It is always more accurate than other methods
(2) It can increase sampling error if clusters are not homogeneous
(3) It requires a complete list of the population
(4) It is never used in large populations
Which of the following is a probability sampling method?
(1) Convenience sampling
(2) Judgmental sampling
(3) Simple random sampling
(4) Quota sampling
Fill in the blank: In ________ sampling, every member of the population has an equal chance of being selected.
Fill in the blank: In ________ sampling, the researcher selects participants who are easiest to reach.
Fill in the blank: In ________ sampling, the researcher uses their own judgment to select participants who are most useful or representative.
Fill in the blank: In ________ sampling, the sample is built by asking initial participants to refer others to the study.
True or False: Convenience sampling is a type of probability sampling.
True or False: In cluster sampling, all individuals within selected clusters are usually included in the sample.
True or False: In quota sampling, the researcher ensures that the sample reflects certain characteristics of the population.
True or False: In stratified sampling, the population is divided into subgroups based on a specific characteristic.
