Sampling Design

+ Info

Deeba needs to conduct a survey for an English Teacher Association. She takes the list of all the members and calls every 15th name on the list. This best illustrates _________

systematic random sampling

stratified random sampling

simple random sampling

1/10

1/10

Systematic sampling involves selection of every nth (i.e., 15th) individual in a population to be in the sample.

Right answer (C):

next

+ Info

select an arbitrary number from the table of random numbers

identify the population

list all members of the population

2/10

In simple random sampling, after a researcher has determined the desired sample size he/she must _____________

2/10

After a researcher has decided to use simple random sampling as his/her sampling design, he/she must do the following steps:1) Make a list of all samples from a population2) Assign a sequential number to each sample. This will be the sampling frame (the list from which a researcher draws his/her simple random sample).3) Figure out what the sample size is going to be. 4) Use a random number generator to select the sample, using the sampling frame (population size) from Step 2 and the sample size from Step 3. For example, if a researcher's sample size is 500 and the population is 5000, generate 500 random numbers between 1 and 5000.

properties

biases

demographics

3/10

3/10

Cluster sampling

Purposive sampling

Convenience sampling

A researcher is conducting a reading intervention study that involves only low achieving students of two schools. The intervention is delivered by the teacher to the entire classes, not the researcher. Which sampling technique is appropriate?

4/10

In a case in which the issue undertudies only involves a specific group of students i.e. low achieving students in reading from two schools, random sampling might not be suitable. Thus, purposive sampling is more appropriate especially if the researcher is using a case study to explore the effectiveness of reading intervention program.

Right answer (B):

+ Info

A researcher uses an ethnographic study that concerns the transitions that refugees students face as they attend mainstream schools. The researcher is particularly interested in the potential differences in the challenges for male and female students face. Which sampling technique is appropriate?

Expert sampling

Theoretical sampling

Homogeneous sampling

5/10

5/10

Homogeneous sampling is a purposive sampling technique that involves selection a homogeneous sample whose units (e.g., people) share the same (or very similar) characteristics or traits

Cluster sampling

Quota sampling

Deviant case sampling

6/10

Which of the following is NOT a type of non-probability sampling?

6/10

Random sampling or known as probability sampling has four types: 1) Simple random sampling, 2) Stratified random sampling (or sometimes, it is referred to as stratified sampling), 3) Systematic random sampling (or sometimes, it is referred to as systematic sampling) and 4) Cluster random sampling (or sometimes, it is referred to as cluster sampling)

Right answer (C):

Which sampling technique can help a researcher to overcome the problem of not having an accessible sampling frame?

+ Info

Multi-stage cluster sampling

Snowball sampling

Quota sampling

7/10

7/10

Snowball sampling can help the researcher to overcome the problem of not having an accessible sampling frame

Right answer (B):

+ Info

Stratified sampling

Multi-stage cluster sampling

Simple random sampling

8/10

When the population is widely dispersed geographically and you have limited time and money available for travelling, which is the best option of random sampling that you can use?

8/10

It is helpful to use a multi-stage cluster sample when the population is widely dispersed geographically and you have limited time and money available for travelling as well as you want to use a probability sample in order to generalise the results.

Right answer (B):

+ Info

When people are readily available, volunteer, or are easily recruited to the sample, this is called __________

convenience sampling

quota sampling

snowball sampling

Convenience sample is a type of non-probability sampling method where the sample is taken from a group of people easy to contact or to reach

Right answer (C):
