Which of the following is not a non-parametric factor in deciding on the specific test to apply?A:    Type of dataB:    Sample sizeC:    Number of groups

The question is asking which factor is not considered when deciding on a non-parametric test to apply. Non-parametric tests are statistical methods used when the data doesn't fit the normal distribution. They don't require the population's parameters (like mean or standard deviation) to be specified.

A: Type of data - This is a factor. Non-parametric tests can be used for different types of data, including ordinal, nominal, and interval data.

B: Sample size - This is also a factor. Non-parametric tests are often used when the sample size is small.

C: Number of groups - This is a factor as well. Different tests are used depending on whether you're comparing two groups or more than two groups.

So, all of the options listed (Type of data, Sample size, Number of groups) are factors in deciding on the specific non-parametric test to apply. Therefore, none of the options listed is the correct answer to the question as it is currently phrased.
