Designs
A design in which the same participants are measured at one point in time.
What is a cross-sectional design?
Sampling method where every member of the population has an equal chance of being selected.
What is simple random sampling?
A question that suggests a preferred answer to participants.
What is a leading question?
A statistical test used to compare means of two groups.
What is a t-test?
The consistency of a measure across items.
What is internal consistency?
A design that follows participants over months or years.
What is a longitudinal design?
Sampling method commonly used in qualitative research based on specific characteristics.
What is purposive sampling?
An example of a nominal variable.
What is gender category, race/ethnicity label, or yes/no response?
A technique used to predict an outcome from one or more predictors.
What is regression analysis?
When a measure accurately reflects the construct it intends to measure.
What is construct validity?
A design where participants serve as their own control group.
What is a within-subjects design?
When participants recruit other participants.
What is snowball sampling?
A numerical scale where zero does NOT represent the absence of the construct
What is an interval scale?
A qualitative method that identifies patterns across transcripts.
What is thematic analysis?
A type of reliability tested by administering a measure twice.
What is test–retest reliability?
When researchers manipulate an independent variable and measure its effect on a dependent variable.
What is an experiment?
Sampling that aims to capture all variation relevant to the research question.
What is maximum variation sampling?
The type of variable that researchers manipulate.
What is an independent variable?
An analysis that tests relationships among latent variables.
What is structural equation modeling (SEM)?
When the relationship between two variables is due to a third variable
What is a confound?
A design that combines quantitative and qualitative data.
What is a mixed-methods design?
A sampling error that occurs when certain groups are systematically underrepresented.
What is sampling bias?
A latent variable measured by multiple scale items.
What is a construct?
A type of modeling used to examine how constructs change over time.
What is latent growth curve modeling?
The extent to which results can be generalized beyond the sample.
What is external validity?
