Quantitative Research I

What is the main goal of descriptive research design?

• To determine if variable increases or decreases as another variable increases or decreases

• To measure a cause from a pre-existing effect

• To answer questions such as who, what, where, when, and how much

• To establish an association between variables

What is the main objective of using stratified random sampling?

• Those who will possibly respond to treatment are chosen

• Every individual will be given an equal chance to be selected

• The sample is taken from an accessible population than the target population

• The sample was chosen proportionately drawn from the different categories of the population

What is the type of validity when an instrument produces results similar to those of another instrument that will be employed in the future?

• Criterion Validity

• Predictive Validity

• Face Validity

• Content Validity

When can we consider a research sample as the 'best'?

• Purposely selected

• Representative of the population

• Systematically chosen

• Conveniently represented

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 experimental research

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

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

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

What is the type of reliability when 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

What statistical technique should be used for this research question, 'Is there a significant difference between the pretest and posttest scores of learners in reading comprehension test'?

• Pearson’s r

• T-Test for independent samples

• Chi Square Test

• T-Test for two dependent samples

What research design aims to determine a cause from already existing effects?

• Correlational Research Design

• Ex Post Facto

• Quasi-Experimental Research

• Descriptive Research Design

What is the suited research design for this research title, 'The Effects of Twitter on the Communication Etiquette of Students'?

• Ex post facto

• Experimental

• Descriptive

• Correlational

What sampling technique is used when the researcher would like to consider giving an equal chance to the member of the accessible population being selected as part of the study?

• Stratified Sampling

• Systematic Sampling

• Cluster Sampling

• Simple Random Sampling
