How is the power of a statistical test defined?
The power of a statistical test is defined as being a probability that a test will product a result that is significantly different. It can be defined as equaling the probability of rejecting the null hypothesis.
Is there a statistical test to assess the difference between two ratios. I have numbers which are ratios and want to test whether there is a statistical difference between them?
You can use the z test for two proportions. The link below will do this test for you.
What statistical test do you use for nominal by ordinal data?
Kruskal-Wallis H test.
What is t Test?
t-test is the statistical test used to find the difference of mean between two groups
In the statistical approach data is collected and used to test what?
To test a prediction based on one of two hypotheses.

What is the power of a statistic?
The power of a statistical test is the probability that the test will reject the null hypothesis when it is, in fact, false. Please see the link.
Is the chi square analysis a statistical test?
It can be, but it is also a statistical distribution in its own right - on which the test is based.
Is the Chi Square test related to statistics?
Yes. It is a statistical test.

What are examples of parametric and nonparametric statistical tests?
Parametric statistical tests assume that your data are normally distributed (follow a classic bell-shaped curve). An example of a parametric statistical test is the Student's t-test.Non-parametric tests make no such assumption. An example of a non-parametric statistical test is the Sign Test.
What variables affect power?
Variables that affect power in a statistical test include the sample size (larger sample sizes increase power), the effect size (larger effect sizes increase power), the significance level (higher significance levels increase power), and the variability in the data (less variability can increase power). Additionally, the chosen statistical test and the presence of confounding variables can also impact the power of a study.
What are the importance ot statistical quality control in weight variation test of capsule?
Unfortunately,there is no importance ot statistical quality control in weight variation test of capsule.
What statistical test do you use for nominal by ordinal data?
Kruskal-Wallis H test.
What has the author Jacob Cohen written?
Jacob Cohen has written: 'Statistical power analysis for the behavioral sciences' -- subject(s): Probabilities, Social sciences, Statistical methods, Statistical power analysis
What is t Test?
t-test is the statistical test used to find the difference of mean between two groups
How do you choose the most appropriate statistical procedure?
To choose the appropriate statistical test, the following four question must be answered; What are your dependent and independent variables? What is scale of measurement of the variables? How many groups/samples are there in the study? Have I have met the assumptions of the statistical test?
