Quantitative Research Flashcards
What is the EXPERIMENTAL method of research?
scientifically acceptable, future predictions, most prestigious and sophisticated due to expense, cause and effect variables
What are the different pre-experimental method types?
- one-shot case study
- one group pretest-posttest
- static group comparison
- true control group pretest-posttest
What is the PRE-EXPERIMENTAL method?
groups are kept under observation after implementing factors of cause and effect
What is the purpose of the pre-experimental method?
to understand whether further investigation is necessary
What is the symbol for the independent variable/treatment?
x
What is the symbol for the dependent variable/measurement?
o
What happens in the one-shot case study method?
single group is exposed to experimental treatment, measurement afterwards
Can you describe the one group pretest-posttest method?
used by behavioral researchers to determine the effect of the independent variable on the dependent variable, measurement before and after
What happens in a static group comparison?
one group receives treatment and the other doesn’t, posttest scores used for comparison
What is the true control group pretest-posttest method?
similar to static, ensures both groups exhibit equal characteristics
What are examples of experimental research?
effects of a teacher’s lecture on quiz results, online discussion versus class discussion
