Research Design and Statistics Quiz

What is the aim Ex post facto research design?

• determine a cause from already existing effects.

• establish cause and effect relationship

• observe and describe a phenomenon

• identify association among variables

"Effects of Type of Music to Aesthetic Performance of Ballet Dancers", what is the appropriate research design for the given title?

• Correlational

• Descriptive

• Survey Research

• Experimental

Mr. Canuc would like to know further the type of social media used between the male and female SHS students of East Pagat National High School. What is the appropriate research design to be used in his study?

• Quasi-Experimental

• Experimental

• Correlational

• Descriptive

Based on item number 3, what appropriate statistical test should Mr. Canuc used to answer his research problem?

• T-test for two dependent samples

• Spearman's rho

• Chi-square

• ANOVA

Which of the following statements is true about the conduct of experimental research?

• There is no random assignment of individuals.

• Individual subjects are randomly assigned.

• Groups are exposed to presumed cause.

• Intact groups are used.

What is the difference between quasi-experimental research and experimental research?

• Only one dependent variable is used in quasi-experimental research, while multiple dependent variables can be used in quasi-experimental research.

• Intact groups are used in experimental, while quasi-experimental randomly assigned individuals into groups.

• Participants for groups are randomly selected in experimental, but not quasi-experimental research.

• The researcher controls the intervention in the experimental group, but not quasi-experimental research.

Why would a researchers choose to use Simple Random Sampling as a sampling technique?

• To consider giving equal chance to the member of accessible population being selected as part of the study.

• To make sure that all subcategories of the population are represented in the selection of sample.

• To group the entire population into clusters since the location of the samples are widely spread.

• To systematically choose samples from a given list of individuals.

When can we consider a research sample as "best?"

• representative of population

• systematically chosen

• conveniently represented

• purposely selected

Given that your study will use stratified random sampling, wherein population of your scope is 250 with a computed sample size of 152, how many samples for each strata will you have if group 1 has 92, group 2 has 86, and group 3 has 72 population?

• Group 1 = 52, Group 2 = 54, Group 3 = 46

• Group 1 = 56, Group 2 = 45, Group 3 = 51

• Group 1 = 52, Group 2 = 52, Group 3 = 44

• Group 1 = 54, Group 2 = 56, Group 3 = 41

What type of reliability is measured by administering two tests identical in all aspects except the actual wording of items?

• Internal Consistency Reliability

• Equivalent Forms Reliability

• Test-retest reliability

• Inter-rater Reliability
