• Regression Analysis. This is a statistical technique used for working out the relationship between two (or more) variables.
• Analysis of Variance (ANOVA) Test.
• Conjoint Analysis.

Can parametric statistical tests be used to Analyse questionnaire data?

With proper consideration of research question and framing of questionnaire, one can also use parametric tests which by any means are more robust than non-parametric tests for analysis provided sample size is large enough to make distribution normal as per central limit theorem.

What do you need to know about statistical testing?

All you have to do is pick the right test for your particular lab experiment or field study. The statistical test that you select will depend upon your experimental design, especially the sorts of Groups (Control and/or Experimental), Variables (Independent and Response), and Treatment Levels that you are working with.

When to use Fisher’s exact test for statistical analysis?

Again we find that there is no statistically significant relationship between the variables (chi-square with two degrees of freedom = 4.577, p = 0.101). The Fisher’s exact test is used when you want to conduct a chi-square test but one or more of your cells has an expected frequency of five or less.

When do you need a nonparametric statistical test?

If your data do not meet the assumptions of normality or homogeneity of variance, you may be able to perform a nonparametric statistical test, which allows you to make comparisons without any assumptions about the data distribution.

How to choose the right statistical test for a table?

You can see the page Choosing the Correct Statistical Test for a table that shows an overview of when each test is appropriate to use.
