To apply the Friedman test to determine whether the locations of two or more populations are the same, the samples must be:

A) from matched pairs experiment
B) from normal populations
C) independent
D) larger than 20
E) from matched pairs experiment and from normal populations

Friedman Test

A technique that employs non-parametric statistical methods to discover differential treatment effects over several testing instances.

Matched Pairs Experiment

A study design where subjects are paired based on certain criteria, and each pair is treated differently to observe the effects of the treatment.

Normal Populations

Populations in which the distribution of a variable follows a normal distribution, characterized by a symmetric bell-shaped curve.

  • Acquire knowledge on the application of the Friedman test for comparative analysis among multiple groups with matched or paired samples.
  • Understand the standards for selecting suitable statistical analyses depending on the data's nature and distribution.

Final Answer :
