 uni- and mutlivariate methods / univariate and multivariate analyses Explanation:Univariate and multivariate methods of statistical analysis are very commonly used in Medicine (and in many other disciplines). A univariate analysis in Medicine, for example, can help identify for a given population with a certain disease what variables predict death. These variables may include age, race, severity of the disease, blood pressure, diet, associated conditions, etc. Once these variables are identified, a multivariate analysis is run to 'adjust' for confounding factors. The univariate variables that were significantly associated with death are tested (i.e., adjusted for). Many variables from the univariate analysis may not longer be predictors of death in the multivariate analysis, that is, they are not "independent" predictors. For ex. "age" usually is an independent (multivariate) predictor of death for any disease, but blood pressure may not be an independent predictor of, say, deaths in colon cancer patients. Thus, a multivariate analysis is a very useful resource to identify the "important" variables among those first identified by the univariate analysis.

Explanation:
Univariate and multivariate methods of statistical analysis are very commonly used in Medicine (and in many other disciplines).

A univariate analysis in Medicine, for example, can help identify for a given population with a certain disease what variables predict death. These variables may include age, race, severity of the disease, blood pressure, diet, associated conditions, etc.

Once these variables are identified, a multivariate analysis is run to 'adjust' for confounding factors. The univariate variables that were significantly associated with death are tested (i.e., adjusted for). Many variables from the univariate analysis may not longer be predictors of death in the multivariate analysis, that is, they are not "independent" predictors. For ex. "age" usually is an independent (multivariate) predictor of death for any disease, but blood pressure may not be an independent predictor of, say, deaths in colon cancer patients.

Thus, a multivariate analysis is a very useful resource to identify the "important" variables among those first identified by the univariate analysis.

univariate and multvariate methods

Explanation:
This is statistical analysis terminology used in scientific studies as is the text:
"...'multivariate statistics.' The word multivariate should say it all -- these techniques look at the pattern of relationships between several variables simultaneously."
The other reference explains univariate statistics.
I hope it helps!
