Null Hypothesis - Yay or Nay ?

    Null Hypothesis - Yay or Nay ?

    Is this a safe barometer to use in experiments. To side with a null hypothesis or actual results? Seems off to me but in practice (very little really) it seems effective.

    Any thoughts ?

    Take a closer look at your stats (P values and degree's of power / alpha), they dictate your yay or nay.

    Definitely the null hypothesis can be useful for where you have a strong idea of what outcome you expect or if you need substantial between group differences. But like you say you can end up on the borderline of whether or not you can safely reject it. I think a combination of hypotheses and qualitative description can be perfect for more modest results or inconsistent findings. You see that alot in some of the work on dyslexia at the moment. You could also use a general research question instead if your not sure what you'll find. So long as you define it accurately its just as scientific.

    Wow, I actually feel dull now.
