How to solve human machine interface problem...... By KATHIRESHAN R


I have doubts regarding the human machine interface of the tool. i.e.
while we are evaluating the null hypothesis we are checking the significance value in the chi-square table and come to a conclusion whether to accept or reject the hypothesis. But the problem is, the chi-square value remains same and the way we define our hypothesis plays an important role. It can clearly be explained by 2 scenarios.

Scenario 1:
Null Hypothesis: Suppose there is no relationship between males who are educated are early married.
We found the significance value to be 0.05 from the chi-square table and hence we come to a conclusion that there is a relationship between males who are educated and early marriage.

Scenario 2:
Null Hypothesis: Suppose if we define there is relationships between male who are educated are early married.
Since the significance value which we obtained from the chi-square table is not changed then it implies that there is no relationships between male who are educated are early married.

These two scenarios contradict each other.

How is this possible and how to solve the human machine interface problem?And how to overcome the assumption made by the software? Is there a better way of defining the hypothesis in the tool?
