What is attrition?
Type of definition regarding how a construct/variable will be measured in the context of a particular study.
What is operational?
The only general study design that allows researchers to evaluate whether there is a cause-and-effect relationship between two variables.
What is an experimental design?
The term that describes extreme scores that are much higher or lower than other scores in a dataset.
What are outliers?
Academic papers that present one or more new research studies conducted by the authors.
What are primary (empirical) sources?
A sampling technique in which researchers only recruit participants from their own community or via word-of-mouth.
What is convenience sampling?
Level of measurement that has equal space between each value on the scale but does not have an absolute zero.
What is interval?
A group of people growing up in the same time period.
What is a cohort?
The statistical measure of the direction and magnitude of the relationship between two variables.
What is Pearson's Correlation Coefficient (r)?
Extraneous variables that vary along with the main variables of interest in a study.
What are confounds?
Type of research in which members of a community play an active role in the design, analysis, and interpretation of the study findings.
What is community-based participatory research (CBPR)?
Type of reliability that allows researchers to determine the degree of consistency across the items on a questionnaire/survey.
What is internal consistency?
The four key requirements for a study to be considered an experiment.
What is 1) at least 1 experimental & 1 control group, 2) at least 1 IV, 3) at least 1 DV, and 4) random assignment?
Term that represents when the effect of one independent variable is dependent on the level of another independent variable.
What is an interaction?
Process in qualitative research that includes identifying and labelling relevant parts of the data to identify key themes.
What is thematic coding?
A sampling technique in which researchers intentionally recruit a certain participant demographic (e.g., gender, race/ethnicity) at a higher percentage than the general population.
What is oversampling?
Type of measurement validity that assesses the extent to which a measure covers the entire scope of the construct.
What is content validity?
Type of group assignment in which all participants complete all study conditions in a randomized order.
What is within-subjects?
Appropriate statistical test for a study with one nominal-level IV (with three groups) and one interval-level DV.
What is a one-way ANOVA?
Assessments that are intended to help track a participant's progress throughout the duration of an intervention.
What are formative assessments/evaluations?
The words that make up the WEIRD acronym.
What is Western, Educated, Industrialized, Rich, and Democratic?
Brain imaging technique that measures brain activity via blood flow while the participant is completing a task.
What is functional magnetic resonance imaging (fMRI)?
An advanced developmental design that allows researchers to compare performance of participants from the same age group at different time points.
What is time-lag?
Group of statistical tests that use the median as the measure of central tendency.
What are non-parametric tests?
One example of a post-hoc test that is used for interpreting the results of an ANOVA.
What is Fisher's LSD, Tukey's HSD, and/or Bonferroni?
