Abstract:
All over the country, millions of research dollars are being spent to devise an effective way of measuring quality that could be standardized in health care, and hospitals and managed care companies are experimenting with a variety of quality tools, trying to document what they now can only perceive as improvement. Experts are divided on what works best, but all applaud and embrace the efforts. In this special report, several of them discuss their views on what works, and what doesn't work, in the exploding field of health care quality measurement.

A set of data measured using the ratio scale takes care of the ratio problem and provides complete information. Ratio scale data are like interval scale data, except they have a zero point and ratios can be calculated. For...
Testing a Claim about Standard Deviation
The hypothesis testing for the claim of population standard deviation (or variance) requires the data and samples to be random and unbiased. The population distribution also must be normal. There is no specific requirement on the sample size as the estimation is based on the chi-square distribution.
As a first step, the hypothesis (null and alternative) concerning the claim about...
