WGU D514 ANALYTICAL METHODS OF
HEALTHCARE LEADERS PRE-TEST TERMS
QUESTIONS & ANSWERS!!
Time-series Answer - Looks at equally spaced points in time; usually to
compare DATA.
Cross-sectional Answer - A specific point in time and/or a specific disease
process in a geographic area.
Pretest-posttest Answer -
Randomized control trial Answer - 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 Answer - Numerical Data
What is a characteristic of qualitative research methods? Answer - Introduces
subjectivity to data collection
Clinical trial Answer - A scientifically controlled study of the safety and
effectiveness of a therapeutic agent
Case study Answer - Non-participant (observational) observation is when
researchers investigate one person, one group, or one institution in depth.
, In Professional Journals
Cohort study Answer - 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 Answer - uses many different data sources (qualitative and
quantitative) to develop 1 conclusion with more evidence and power.
Applies analysis to a problem
Literature review Answer - informational and reading about the research may
help you to make decisions
Longitudinal study Answer - Same as cohort (people are studied over a long
period of time)
Answer -
Analysis of variance ( Answer - ANOVA: compare means between independent
variables with similar variance and normality of distribution.
COMPARE MULTIPLE groups
Pearson correlation coefficient Answer - Test for a relationship between two
quantitative variables that are interval or ratio data types.
