  3. WASON CARD SORT LEARNING OUTCOMES BY THE END OF THE SESSION, YOU SHOULD BE ABLE TO: Use SPSS to test the first experimental hypothesis of the Wason card sorting experiment and produce a related graph. Use SPSS to test the second experimental hypothesis of the Wason card sorting experiment and produce a related graph. Use the graphs to interpret your chi-square findings. Make a start on writing up your RESULTSandDISCUSSION sections for your lab report.

  4. WASON CARD SORT METHOD RECAP DESIGN Half of the people in the room did the concrete first, half did the abstract. ABSTRACT CONCRETE CONCRETE ABSTRACT then then Research Questions Base your hypotheses on the following research questions: Q1: Is performance better on some versions of the Wason card sorting task than others the first time it is performed? ABSTRACT CONCRETE CONCRETE ABSTRACT then then Q2: Is performance on the abstract task affected if it follows a concrete scenario? ABSTRACT CONCRETE CONCRETE ABSTRACT then then

  5. WASON CARD SORT RESULTS The third column shows whether the individual got their first problem right or wrong. The first column shows subject number. And yes, there are 180. 1 = RIGHT 2 = WRONG The second column shows which type of problem each individual solved first. The fourth column shows whether the individual got the abstract problem right or wrong. 1 = ABSTRACT 2 = CONCRETE 1 = RIGHT 2 = WRONG

  6. WASON CARD SORT RESULTS Let’s make the data look a little more meaningful by changing the numeric values into textual values. Go to variable view and select values. For first_problem, CORRECT1 and CORRECTA, associate the values (e.g., 1, 2) with the appropriate value labels (e.g., abstract, concrete; wrong, right). first_problem 1 = ABSTRACT 2 = CONCRETE CORRECT1 1 = RIGHT 2 = WRONG CORRECTA 1 = RIGHT 2 = WRONG

  7. WASON CARD SORT RESULTS Q1: Is performance better on some versions of the Wason card sorting task than others the first time it is performed? CONCRETE (1st) vs. ABSTRACT (1st) If we are interested in comparing categorises of responses, then the chi-square test is appropriate. In SPSS, the chi-square test is hidden away underneath descriptive statistics > crosstabs. Let’s go there now.

  8. WASON CARD SORT RESULTS Q1: Is performance better on some versions of the Wason card sorting task than others the first time it is performed? CONCRETE (1st) vs. ABSTRACT (1st) In order to build a chi-square table, we need to put our various categories into rows and columns. Let’s put first_pr as a row and CORRECT1 as a column. This will show us the frequency distributions. Under statistics, we also need to make sure the chi-square test is performed, so tick that. Under cells, also make sure that both observed and expected are clicked.

  9. WASON CARD SORT RESULTS Q1: Is performance better on some versions of the Wason card sorting task than others the first time it is performed? CONCRETE (1st) vs. ABSTRACT (1st) The second table (after case processing summary) confirms our 180 observations and displays the frequency distribution of right and wrong responses for the two kinds of Wason card sort test. The third table provides us with the chi-square value, which may be reported as: χ2 (1) = 19.74, p < .001

  10. WASON CARD SORT RESULTS Q1: Is performance better on some versions of the Wason card sorting task than others the first time it is performed? Chi-square value Significance level Degrees of freedom χ2 (1) = 19.74, p < .001

  11. WASON CARD SORT RESULTS Q1: Is performance better on some versions of the Wason card sorting task than others the first time it is performed? You will need to graphically represent your results, too Don’t forget to give your Figure a number and a title When you refer to the Figure in the main text, make sure you give the exact descriptive statistics Note: no error bars, because this is categorical data

  12. WASON CARD SORT RESULTS Q2: Is performance on the abstract task affected if it follows a concrete scenario? ABSTRACT (1st) vs. ABSTRACT (2nd) If we are interested in comparing categorises of responses, then the chi-square test is appropriate. In SPSS, the chi-square test is hidden away underneath descriptive statistics > crosstabs. Let’s go there now.

  13. WASON CARD SORT RESULTS Q2: Is performance on the abstract task affected if it follows a concrete scenario? ABSTRACT (1st) vs. ABSTRACT (2nd) In order to build a chi-square table, we need to put our various categories into rows and columns. Let’s put first_pr as a row and CORRECTA as a column. This will show us the frequency distributions. Under statistics, we also need to make sure the chi-square test is performed, so tick that. Under cells, also make sure that both observed and expected are clicked.

  14. WASON CARD SORT RESULTS Q2: Is performance on the abstract task affected if it follows a concrete scenario? ABSTRACT (1st) vs. ABSTRACT (2nd) The second table (after case processing summary) confirms our 180 observations and displays the frequency distribution of right and wrong responses for the two kinds of Wason card sort test. The third table provides us with the chi-square value, which may be reported as: χ2 (1) = 0.53, p = .47

  15. WASON CARD SORT RESULTS Q2: Is performance on the abstract task affected if it follows a concrete scenario? Once again, you will need to graphically represent your results Don’t forget to give your Figure a number and a title When you refer to the Figure in the main text, make sure you give the exact descriptive statistics Note: no error bars, because this is categorical data If you have trouble, refer back to the Excel graph-making guides on Graham’s webpage, or ask a tutor for help

  16. WASON CARD SORT DISCUSSION GET TOGETHER IN GROUPS OF THREE OR FOUR AND REFLECT ON TODAY’S EXPERIENCE USING THE FOLLOWING QUESTIONS Why have I done this particular statistical test? What do the data actually tell me with respect to my experimental hypotheses? What implications do the data have for the studies outlined in the intro?

  17. SAMPLING DISTRIBUTIONS LEARNING OUTCOMES BY THE END OF THE SESSION, YOU SHOULD BE ABLE TO: Use SPSS to test the first experimental hypothesis of the Wason card sorting experiment and produce a related graph. Use SPSS to test the second experimental hypothesis of the Wason card sorting experiment and produce a related graph. Use the graphs to interpret your chi-square findings. Make a start on writing up your RESULTSandDISCUSSION sections for your lab report.
