WASON CARD SORT 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.
