Research Terms Flashcards
systemic investigations that include inductive, in-depth, studies of how individuals, groups and organizations or communities; focuses on the why and how of decision making to better understand human bx
Qualitative Research
factor that can be varied/manipulated in an experiment
Independent variable
degree to which an instrument measures the characteristic being investigated
construct validity
systematic investigations that include descriptive/inferential statistical analysis
Quantitative Research
experimental research with a control and experimental group, but w/o random assignment
Quasi-Experimental Research
in social research, the concept concerned w/the extent to which a procedure is able to measure the quality it is intended to measure
Validity
phenomenon/ reaction to be tested or measured when a new stimulus, condition, or treatment is introduced
dependent variable
extent to which study findings can be generalized beyond the sample used in the study
external validty
questionnaire or other data-gathering instrument administered to a subject just before a period of inquiry that provides a baseline for comparison w/the end results
pretest
research conducted under carefully controlled conditions, in which the subjects being investigated are randomly selected and systematically compared w/control groups, w/treatment variables being introduced to the experimental group but bot the control group, and the use of stats analysis to determined if significant different occur btwn the groups obeserved
experimental study
a research procedure often used in clinical situations to evaluate the effectiveness of an intervention; the bx of an individual pt is used as a comparison and a control
single-subject design
degree to which different people give similar scores for the same observations; refers to the consistency of a measure
inter-rater reliability
middle score
median
repeated testing of the same phenomenon or group of subjects over an extended period
longitudinal study
extent to which the effects detected in a study are truly caused by the treatment or exposure in the study sample, rather than being due to other biasing effects of extraneous variables
internal validity
type of study design used to explore or gain insights into a phenomenon
exploratory study
value that occurs most frequently
mode
use of change procedures in psychology experiments to ensure that each participant has the same opportunity to be assigned to any given group
random assignment
process of searching published work to find out what is known about a research topic
lit review
average value/measure of central tendency
mean
a mutual relation; a pattern of variation btwn 2 phenomena in which change in one is associated w/change in the other
correlation
in research, a collection of subjects who are matched and compared w/a control group in all relevant respects, except that they’re also subject to a specific variable being tested
experimental group
statement that no relationship exists btwn study variables
null hypothesis
a procedure for testing and validating a questionnaire or other instrument by. administering it to a small group of respondents from the intended test population; the procedure helps determine whether thetest items possess the desired qualities of measurement and the ability to discriminate against other probs beforethe instrument is put to widespread use
pilot study
questionnaire or other data-gathering instrument administered to a subject at the endo f a specific period of inquiry
posttest
