What else can I help you with?
Is parametric test stronger than nonparametric test?
If the distribution is parametric then yes.
Convert nonparametric to parametric data?
log 10 or square root your non parametric values
What is the difference between parametric and non parametric?
Nonparametric tests are sometimes called distribution free statistics because they do not require that the data fit a normal distribution. Nonparametric tests require less restrictive assumptions about the data than parametric restrictions. We can perform the analysis of categorical and rank data using nonparametric tests.
What nonparametric test does not have comparable parametric test?
A classic would be the Kolmogorov-Smirnov test.
What are the three differences between parametric and non-parametric statistics?
1. A nonparametric statistic has no inference 2. A nonparametric statistic has no standard error 3. A nonparametric statistic is an element in a base population (universe of possibilities) where every possible event in the population is known and can be characterized * * * * * That is utter rubbish and a totally irresponsible answer. In parametric statistics, the variable of interest is distributed according to some distribution that is determined by a small number of parameters. In non-parametric statistics there is no underlying parametric distribution. With non-parametric data you can compare between two (or more) possible distributions (goodness-of-fit), test for correlation between variables. Some test, such as the Student's t, chi-square are applicable for parametric as well as non-parametric statistics. I have, therefore, no idea where the previous answerer got his/her information from!

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 is the difference between parametric and nonparametric statistical tests in Health care?
Parametric tests draw conclusions based on the data that are drawn from populations that have certain distributions. Non-parametric tests draw fewer conclusions about the data set. The majority of elementary statistical methods are parametric because they generally have larger statistical outcomes. However, if the necessary conclusions cannot be drawn about a data set, non-parametric tests are then used.
What are the advantages and disadvantages of nonparametric statistics compared to the parametric statistics?
Non-Parametric statistics are statistics where it is not assumed that the population fits any parametrized distributions. Non-Parametric statistics are typically applied to populations that take on a ranked order (such as movie reviews receiving one to four stars).

Why are nonparametric tests not the first choice in statistical procedures?
There are several reasons, including the following, in no particular order:I suspect that many or most people learn the parametric alternatives first, or learn mainly the parameteric alternatives.When the correct conditions hold, the parametric alternatives provide the best power.In some situations, such as the more complicated ANOVA and related methods, there are no nonparametric alternatives.Often data that do not appear to satisfy the requirements for parametric procedures can be transformed so that they do, more or less.Parametric procedures have been shown to be robust in the face of departures from the assumptions on which they were based, in many cases.

What is the difference between parametric and nonparametric statistical tests?
Parametric are the usual tests you learn about. Non-parametric tests are used when something is very "wrong" with your data--usually that they are very non-normally distributed, or N is very small. There are a variety of ways of approaching non-parametric statistics; often they involve either rank-ordering the data, or "Monte-Carlo" random sampling or exhaustive sampling from the data set. The whole idea with non-parametrics is that since you can't assume that the usual distribution holds (e.g., the X² distribution for the X² test, normal distribution for t-test, etc.), you use the calculated statistic but apply a new test to it based only on the data set itself.
Chi square is used in nonparametric hypothesis test?
Yes, Chis squared test are among the most common nonparametric statistics tests.
The data you are comparing is both parametric for one set and non-parametric for another Is there anything that can test this?
Parametric for one set?! Yeah
