Here is the
'using the sign test' sheet which was the first statistics homework I set.
Here is the
'choosing a statistical test' flowchart which you need to learn (for your statistics test on Tuesday 16th July).
Here is the
'significant or not significant?' sheet which we had a go at in the lesson today.
Here is the
'four more tests to do' sheet which forms part of your homework for the next Tuesday.
You also need to produce a short write-up for each of the experiments that we have done. Your write up should look like a couple of sides (handwritten) or one side typed and include the following:
- Title and date
- Aim of the investigation
- Null and alternative hypotheses (operationalised)
- Procedure – very brief outline (3-5 lines)
- Results table
- Justification of statistical test
- Level of significance chosen
- Working for test
- Explanation of level of significance reached and conclusion
The questions we have addressed in our recent lessons are:
Is it easier to locate a face in a crowd with eyes looking at you than with eyes looking to the side?
Is there a difference between the verbal reasoning skills of male and female students?
Are your judgements of how hard you have worked and your intelligence related to how well you think you have done in your exams?
Are women more likely than men to mention their own looks in a personal ad?
Here are the results for these, with calculations still to complete.
