    Average height of european men is now 180 cm, 1870 it was 169. Thus, what do you think could be the null hypothesis?

    Of course, someone could write and post a thesis here.

    Alternatively, eatmanian could do a simpel google search for:
    null hypothesis
    (as I did. And I found lots of explanations.) and write something himself and then ask here if he has got it correct. One often learns something when trying to formulate it in words and math.

    Re: Example Research Questionthe null hypothesis


    You can make your null whatever you want but typically the are related to no differences between group regardless of direction, Ho: mean of group 1 = mean of group 2;


    Still waiting to see what you come up with?
