Discuss the following statement: Multivariate analyses can be run on any data set, as long as the sample size is adequate.
Homework Answers
Analysis can be performed on the sample of any size, but the sensitivity (or precision) of the results depends on the sample size severely. Hence, the "minimal sample size" depends upon what precision is enough for your particular problem, i.e. the magnitude of differences that you want to prove to be statistically significant.
The sample size for multivariate analysis should be at least 10 times the number of independent variables.
