Final Answer :
True
Explanation :
The Friedman test is used to determine whether two or more groups differ, while the sign test is used to compare two paired samples. However, both tests can be used to draw conclusions about the statistical significance of observed differences between groups. Therefore, the conclusion drawn from the Friedman test will generally be the same as that produced from the sign test.
