Practical Research Summative Flashcards
(235 cards)
The researchers use ______________
to avoid being bias in the selection of the sample for their study.
random sampling
This is known as the selection of components of the sample that will give a representative view of the whole.
Sampling Technique
What do you call the selection of sample unbiasedly?
Probability Sampling
This refers to a sampling technique in which samples are obtained using some objective chance mechanism, thus involving randomization.
Probability Sampling
- If your population is less than ___, go away from probability sampling.
- Your sample size should be at least ____.
- 50
- 30
_____________ give all elements of the population an equal chance of being selected but using this technique may consume a lot of time and effort of the researchers.
Probability sampling techniques
What are the 5 types of probability sampling techniques used in quantitative research?
Simple Random Sampling
Systematic Random Sampling
Stratified Random Sampling
Cluster Sampling
Multi-Stage Sampling
Triple S CM
Probability Sampling Techniques. This is the basic probability sampling design in which the chance of selection is THE SAME for every member of the population.
Simple Random Sampling
Probability Sampling Techniques. It is a sampling that follows regular INTERVALS from a list.
Systematic Random Sampling
Probability Sampling Techniques. The population is divided into groups called a. __________ and then simple random sampling is applied in selecting samples from each group.
Stratified Random Sampling
a. Strata
Probability Sampling Techniques. Used when the study is spread across a geographical location. In this, the population is group into CLUSTER.
[Simple Random is used in selecting the cluster]
Cluster Sampling
Probability Sampling Techniques. This refers to the procedure as in cluster sampling which moves through a SERIES OF STAGES.
Multi-Stage Sampling
Simple Random Sampling. Ways of selecting samples:
- Utilizing a table of random number
- Using lottry techniques/fishbowl method
- Using digital random picker application
Steps in Systematic Random Sampling:
- Number participants in the population from 1 to N
- Compute for sample size (x)
- Divide population to desired sample size (N/x)
- Randomly pick a number between 1 to the value obtained in step 3.
- Start counting from the number you get in step 4 using the interval you get from step 3.
Stratified Random. How to find the group sample size using the total population and total sample size?
Multiple the percent of the group (group population/total population) to the total sample size.

B. Probability sampling is a subjective type of selecting a sample.
C. Probability sampling involves randomization in selecting a sample.
D. Probability sampling gives an unequal chance of selection for every element of the population.
C. Probability sampling involves randomization in selecting a sample.
