Patient satisfaction is a measure of the extent to which a patient is content with the health care which they received from their health care provider. In evaluations of health care quality , patient satisfaction is a performance indicator measured in a self-report study and a specific type of customer satisfaction metric.
The table shown on the right can be used in a two-sample t-test to estimate the sample sizes of an experimental group and a control group that are of equal size, that is, the total number of individuals in the trial is twice that of the number given, and the desired significance level is 0.05. [4]
One method of research for evidence-based practice in nursing is 'qualitative research': The word implies an entity and meanings that are not experimentally examined or measured in terms of quantity, amount, frequency, or intensity. With qualitative research, researchers learn about patient experiences through discussions and interviews.

The dominant research method is the randomised controlled trial. Qualitative research is based in the paradigm of phenomenology, grounded theory, ethnography and others, and examines the experience of those receiving or delivering the nursing care, focusing, in particular, on the meaning that it holds for the individual
For example, a review of 37 studies addressing different methods of satisfaction evaluation found that phone interview increased the response rate by 30%. [5] Additionally, mailing surveys resulted in more criticism and less satisfaction. Some speculate that this is due to the anonymity and a lack of pressure for socially acceptable responses.
In the design of experiments for estimating statistical models, optimal designs allow parameters to be estimated without bias and with minimum variance. A non-optimal design requires a greater number of experimental runs to estimate the parameters with the same precision as an optimal design. In practical terms, optimal experiments can reduce ...
The main idea of RSM is to use a sequence of designed experiments to obtain an optimal response. Box and Wilson suggest using a second-degree polynomial model to do this. They acknowledge that this model is only an approximation, but they use it because such a model is easy to estimate and apply, even when little is known about the process.
