    One Tailed test




    For a positive one tailed test, if the obtained value falls to the left of the critical value, do you retain the null or is there an error?

    How is this different from your previous question?

    Well, I believe you would reject the null since it is to the left of the critical value. My previous question wasnt about the null, but rather values. Want to make sure I have this down

    since the value is outside, there would be no relationship the the hypothesis, right?

    You would not have evidence to reject the null hypothesis. This doesn't mean that the null is true or that there is high probability that the null is true - just that you don't have evidence that the null is false.

    Re: One Tailed test

    So would there be an error in the data or an error in the calculations? My instincts says both, but I know that cant be true!

    OK, so do not reject the null, or retain the null is correct, light bulb! Thanks again!

    Just because you fail to reject the null definitely not mean you have an error in the data. It's possible to have errors in your data but just failing to reject the null doesn't mean that there are errors.
