Research Design Flashcards
Focus on explaining and understanding experiences and perspectives.
Qualitative Research
Focus on quantifying and measuring phenomena.
Quantitative Research
Use of non-numerical data, such as words, images, and observations.
Qualitative Research
Use of numerical data, such as statistics and surveys.
Quantitative Research
Usually uses larger sample sizes.
Quantitative Research
Usually uses small sample sizes.
Qualitative Research
Typically emphasizes in-depth exploration and interpretation.
Qualitative Research
Data analysis involves interpretation and narrative analysis.
Qualitative Research
Typically emphasizes precision and objectivity.
Quantitative Research
The researcher does not have this level of control and must rely on observations and measurements of naturally occurring variables.
Non-experimental research
Data analysis involves statistical analysis and hypothesis testing
Quantitative Research
Results are presented numerically and statistically.
Quantitative Research
The researcher has complete control over the independent variable and can manipulate it to test the hypothesis.
Experimental research
Results are presented descriptively.
Qualitative Research
A type of Quantitative Design that attempts to determine the extent of a relationship between two or more variables using statistical data
Correlational research
A type of Quantitative Design that attempts to establish cause effect relationships among the variables.
Causal - Comparative / Quasi Experimental research
Is the group that receives the variable being tested in an experiment.
Experimental group
A type of Quantitative Design that uses the scientific method to establish the cause-effect relationship among a group of variables that make up a study
Experimental research / True experimentation
A type of Quantitative Design that seeks to describe the current status of an identified variable.
Descriptive research
Is the group in an experiment that does not receive the variable you are testing.
Control group
The treatments are assigned completely at random so that each experimental unit has the same chance of receiving any one treatment.
Completely Randomized Design (CRD)
A key principle of Research Design that ensures that what should be measured is being measured. It also increases the range of application of the results to a wider range of other similar conditions.
Validity
Defined by an experiment whose treatment combinations are assigned randomly to the experimental units within a block.
Randomized Complete Block Design (RCBD)
A key principle of Research Design that refers to the degree to which the design can detect differences between treatments.
