Question 45
As regards the difference between the first and the last level of participants’ heart rate, Figure 11.12c tells you that…
the difference between level 1 and 7 is not significant (p = .678);
the difference between level 1 and 7 is not significant, but you do not know the value of p;
you need to run another test using a different contrast to find out;
the difference between level 1 and 7 must be significant as well: that between the first and the second is, and from the second onwards we do not see significant differences.
