In a Friedman test for comparing three populations, provided that there are five blocks, the test statistic is calculated as In a Friedman test for comparing three populations, provided that there are five blocks, the test statistic is calculated as   = 6.594. Then, the most accurate statement that can be made about the p-value is that: A)  p-value < 0.01 B)  .05 < p-value < .10 C)  .025 < p-value < .05 D)  p-value > .10 E)  0.01< p-value < 0.025 = 6.594. Then, the most accurate statement that can be made about the p-value is that:

A) p-value < 0.01
B) .05 < p-value < .10
C) .025 < p-value < .05
D) p-value > .10
E) 0.01< p-value < 0.025

Friedman Test

This non-parametric approach is utilized to identify distinctions in treatments throughout multiple testing sessions.

Test Statistic

A value calculated from sample data during a hypothesis test, used to decide whether to support or reject the null hypothesis.

P-value

A statistical measure that helps determine the significance of results obtained in hypothesis testing, indicating the probability of observing the obtained results if the null hypothesis were true.

Final Answer :
C
Explanation :
With a test statistic of 6.594 and 5 blocks, we need to consult the appropriate Friedman test table for p-values (or use a statistical software). Looking at the table, we find that the p-value for a test statistic of 6.594 and 5 blocks is between 0.025 and 0.05. Therefore, the most accurate statement is that .025 < p-value < .05.
