D514 Analytical Methods of
Healthcare Leaders Pre-Test Terms
Time-series
Looks at equally spaced points in time; usually to compare DATA.
Cross-sectional
A specific point in time and/or a specific disease process in a geographic area.
Randomized control trial
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
Numerical Data
What is a characteristic of qualitative research methods?
Introduces subjectivity to data collection
Clinical trial
A scientifically controlled study of the safety and effectiveness of a therapeutic
agent
Case study
Non-participant (observational) observation is when researchers investigate one
person, one group, or one institution in depth.
In Professional Journals
Cohort study
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
uses many different data sources (qualitative and quantitative) to develop 1
conclusion with more evidence and power.
Applies analysis to a problem
Literature review
informational and reading about the research may help you to make decisions
Longitudinal study
Same as cohort (people are studied over a long period of time)
Analysis of variance (
ANOVA: compare means between independent variables with similar variance and
normality of distribution.
COMPARE MULTIPLE groups
Pearson correlation coefficient
Test for a relationship between two quantitative variables that are interval or ratio
data types.
Ex. Blood pressure and age
Mann-Whitney U test
Compares 2 samples from the same population to see if they are equal or not.
++ sometimes used for comparing the effectiveness of two treatments in clinical
trials.
Bayesian approach
An advanced mathematical procedure that applies probabilities to statistical
problems.
Helps people to update their beliefs
Regression analysis
