Quantitative Research 1
What type of variable is manipulated or controlled by the researcher in an experiment?
This type of assessment compares an individual's performance against a predetermined standard.
Criterion-referenced assessment
This threat to internal validity occurs when participants drop out of a study.
What is attrition threat?
This measure of variability describes the spread of data around the mean
What is standard deviation?
Researchers observe and interact with participants in their natural environment to understand their behaviors and experiences.
What is ethnography?
Variables that can influence the outcome of an experiment but are not the focus of the study are known as what type of variables?
This epidemiological measure represents the number of new cases of a condition in a population during a specific time period
What is incidence?
This threat to internal validity occurs when changes are due to the passage of time rather than experimental manipulation.
What is history threat?
This statistical test is used to determine if there is a significant difference between the means of two normally distributed independent groups
What is "independent t-test"
Involves gathering data through open-ended, semi-structured, or unstructured interviews to explore participants' perspectives and experiences.
What is a phenomenological study?
This type of non-experimental research involves observing and describing phenomena without manipulating variables.
What is descriptive research?
What type of reliability refers to the consistency of scores when different observers assess the same individuals
What is inter-rater reliability
This threat refers to the tendency of individuals to change their behavior simply because they are being observed or studied.
What is the Hawthorne effect?
This test is used to compare the means of three or more groups to determine if there are statistically significant differences between them.
This trustworthiness method uses triangulation and member checking
What is credibility?
This type of experimental design involves the manipulation of more than one independent variable.
What is a factorial design?
This type of validity evaluates whether scores on a measurement instrument are related to measures of different constructs
What is divergent validity?
This type of study design follows a group of individuals over time, recording their exposures and subsequent outcomes.
What is prospective cohort study?
This type of regression analysis is the dependent variable categorical, typically representing binary outcomes like success/failure or yes/no.
What is logistic regression?
This trustworthiness method uses an audit trail and multiple coders
What is dependability
This type of non-experimental design looks at relationships between conditions but does not manipulate any variables.
What is correlational research?
This testing measure assesses the proportion of true positives correctly identified by a test among individuals who actually have the condition.
What is sensitivity?
This type of prognostic study design is observational, retrospective, and cross-sectional.
What is case control study?
This statistical test is used to determine if there is a significant association between frequencies of two categorical variables
What is Chi-Square Test?
This trustworthiness method uses reflexive journaling and saturation
What is confirmability?
