Let's elaborate these simple ideas!

The Null Hypothesis (H_o)
Null = Nothing = Zero = Nada = Bupkus = Zilch

• You didn't find an effect.
• You didn't find the groups to be different.
• Your treatment doesn't seem to help anybody.
• Your variables are not related.

Statistical Things to Know:
You test your sample statistic against the value based on the Null Hypothesis sampling distribution.

Your sample statistic and Null Hypothesis sampling distribution values are close.

You conclude that they are not different; you did not find an effect in your study.
