In this task I ask students to complete the worksheet by identifying the different types of hypotheses. I illustrate each hypothesis as a fish!
- The fishes with 2 tails (are two-tailed / non-directional hypotheses). I normally pretend the fishes are busy in conversation (or kissing) so therefore are distracted and no direction!
- The fish with 1 tail is a one-tailed / directional hypothesis. I say to my students that its vision is clear so it can see where it is going.
- The fish with no tail is a null hypothesis. Unfortunately having no tail means it limits its significance and can't be of much use.
I hope this helps!
