3. BY THE END OF THE SESSION, YOU SHOULD BE ABLE TO:
WASON CARD SORT
LEARNING OUTCOMES
BY THE END OF THE SESSION, YOU SHOULD BE ABLE TO:
Understand the way in which the practical reports will be marked and what you have to do to do well!
Learn to calculate chi-squares by hand (these hand calculations are a critical skill for the exam).
Tackle an additional problem sheet which should help you more fully understand the principles behind non-parametric tests.
Clarify any additional problems that you may have regarding this lab report with your friendly neighbourhood demonstrators.

YOUR CHOICE
YOU HAVE THE REST OF THE SESSION TO FOCUS ON WHAT YOU THINK YOU NEED TO IMPROVE YOUR UNDERSTANDING
LAB REPORT
CHI-SQUARE BY HAND
NONPARAMETRICS
Make sure you are happy with your interpretation of the SPSS output in relation to the two experimental hypothesis and make sure you know what needs to go into your lab report to get the best marks.
Try working through the second experimental hypothesis on the ‘wasonbyhand.doc’ handout and compare your hand results with the results you obtained from SPSS.
Download ‘problem4’ and start to work through the questions related to lots of different nonparametric tests. The answers will be made available in a couple of weeks time.
