What is the power of a statistical test?
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 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 is a statistical problem?
The statistical problem helps to describe the whole issue of descriptive and inferential statistics. The main aspects of the statistical problems are the population should be clearly defined and also objectives.
What statistical test do you use for nominal by ordinal data?
Kruskal-Wallis H test.
What is t Test?

It can be, but it is also a statistical distribution in its own right - on which the test is based.

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.
Why were metropolitan statistical areas defined?
Metropolitan statistical areas were defined by the U.S. Office of Management and Budget to provide a consistent definition of metropolitan areas for statistical data collection and analysis. These areas help in understanding population trends, economic activities, and urban development patterns in a standardized way across the country.
