Quantitative and/or Qualitative?
Types of Designs and Approaches
Data Analysis
100
In a statistical analysis, this is the primary outcome measure of interest.
What is the dependent variable?
100
In this type of research, unstructured interviews may be used to understand the primary thoughts and concerns of a particular population
What is qualitative research?
100
This study design randomly assigns participants into an experimental group or a control group. As the study is conducted, the only expected difference between the control and experimental groups is the outcome variable being studied.
What is a randomized controlled trial?
100
Many health interventions are interested in the change in health after the onset of a new program. This analysis would be used to test whether health post-intervention is better than health pre-intervention.
What is a (paired/dependent) t-test? (Also acceptable, "What is a repeated measures ANOVA?")
200
This variable's name literally refers to a variable that varies with another variable, and it is often statistically controlled for during certain analyses.
What is a covariate?
200
This type of research focuses on empirical observations that can be measured.
What is quantitative research?
200
This design shares similarities with the traditional experimental design or randomized controlled trial, but it specifically lacks the element of random assignment to groups.
What is a quasi-experimental design?
200
This analysis would be used to compare the GPAs of male and female students.
What is a One-Way ANOVA? (Also accepted, "What is an indepedent-samples/unpaired t-test?")
300
In a regression analysis, this type of variable can be used to find an estimated value for the outcome variable.
What is a predictor?
300
This type of research utilizes statistical analysis.
What is quantitative research?
300
This design aims to depict the participants accurately, without influencing them in any way.
What is a descriptive design?
300
This analysis should be used to examine differences in two categorical variables, such as how diabetes diagnosis differs between Whites and African Americans.
What is a chi-square test?
400
This type of categorical variable only has two categories or levels.
What is a dichotomous variable?
400
This type of research, which follows one individual, is often associated with qualitative research, but may still utilize quantitative evidence.
What is a case study?
400
This design involves one or more samples who are followed prospectively, and are subsequently evaluated regarding a disease or outcome to determine which initial participants' risk factors are associated with it.
What is a cohort design?
400
Researchers frequently use this analysis in the interaction between two categorical variables--for example, to test whether the effect of a treatment/control group is different for people with the blood type O+ versus O-
What is a factorial ANOVA? (Also accepted, two-way ANOVA/ 2 x 2 ANOVA)
500
This type of variable is not purposefully manipulated, but may systematically affect the outcome of an experiment.
What is a confound?
500
This type of research refers to a combination of qualitative and quantitative data gathering.
What is mixed-methods research?
500
This partnership approach to research equitably involves, for example, community members, organizational representatives, and researchers in all aspects of the research process and in which all partners contribute expertise and share decision making and ownership.
What is community base participatory research (CBPR)?
500
This method is used to compare different groups, while controlling for the effect on a different variable. For example, to compare males and females on risk of hypertension, while controlling for BMI.
What is ANCOVA?
