Results
First, this section discusses whether rejection of the null hypothesis should be an all-or-none proposition. Then, it discusses how to interpret non-significant results; for example, it explains why the null hypothesis should not be accepted or should be accepted with caution. It also describes how a non-significant result can increase confidence that the null hypothesis is false.

Question 2 out of 2.
You have just given a group of 2nd graders and 1st graders a reading test. You found that the 2nd graders performed better than the 1st graders, but you calculated a 
value of.08, which was not significant at the.05 level. After getting these results, what should your thoughts be about the difference between 1st and 2nd graders on this reading test?
- You are more confident that there is a difference.
- You are less confident that there is a difference.
- You now know that the difference is actually zero.
