WGU D514 Analytical Methods of
Healthcare Leaders Pre-Test Terms
Fully solved
Time-series - ANS ✔✔Looks at equally spaced points in time; usually to compare DATA.
Cross-sectional - ANS ✔✔A specific point in time and/or a specific disease process in a
geographic area.
Pretest-posttest - ANS ✔✔
Randomized control trial - ANS ✔✔people are allocated at random (by chance) to receive one of
several clinical interventions. One of the interventions is the "control", which may be standard
practice, a placebo, or no intervention at all.
quantitative research - ANS ✔✔Numerical Data
What is a characteristic of qualitative research methods? - ANS ✔✔Introduces subjectivity to
data collection
Clinical trial - ANS ✔✔A scientifically controlled study of the safety and effectiveness of a
therapeutic agent
Case study - ANS ✔✔Non-participant (observational) observation is when researchers
investigate one person, one group, or one institution in depth.
In Professional Journals
, Cohort study - ANS ✔✔medical research used to investigate the causes of disease, establishing
links between risk factors and health outcomes
CARRIED OUT OVER FUTURE periods of time
Meta-analysis - ANS ✔✔uses many different data sources (qualitative and quantitative) to
develop 1 conclusion with more evidence and power.
Applies analysis to a problem
Literature review - ANS ✔✔informational and reading about the research may help you to make
decisions
Longitudinal study - ANS ✔✔Same as cohort (people are studied over a long period of time)
Analysis of variance ( - ANS ✔✔ANOVA: compare means between independent variables with
similar variance and normality of distribution.
COMPARE MULTIPLE groups
Pearson correlation coefficient - ANS ✔✔Test for a relationship between two quantitative
variables that are interval or ratio data types.
Ex. Blood pressure and age
Mann-Whitney U test - ANS ✔✔Compares 2 samples from the same population to see if they
are equal or not.
