BartlettвЂ™s test of sphericity was significant (.32. 74 and therefore suggests the sample is adequate for Factor Analysis. The Kaiser-Meyer-Olkin measure of sampling adequacy is. Kaiser-Meyer-Olkin measure of sampling adequacy We must now look at the KMO measure of sampling adequacy and BartlettвЂ™s test of sphericity ( Table 3).

This reflects the overall measurement of вЂњOverall satisfaction with life,вЂќ where the higher the score, the more positive the person feels about overall satisfaction.ДЇigure 1 below shows how to recode the variable on SPSS. Therefore, if someone originally answered a score of 10 for anxiety, this will be inputted as 0, so that when Factor Analysis is conducted, it measures all variables as high scores reflecting positive answers. All we have to do in this case is reverse code, so that 10 will equal 0. Therefore, it is up to us to ensure that the coding of each statement is consistent. However, when running Factor Analysis, the software does not know happiness and anxiety elicit different emotions. This is further reflected with a mean anxiety score of 2.8 on a scale of 0вЂ“10. The measures of central tendency displayed in Table 2 indicate that the sample is quite positive in terms of happiness with a mean score of 7.6 in a scale of 0вЂ“10. Overall, how satisfied are you with the balance between time spent on paid job and the time spent on other aspects of life? Overall, how satisfied are you with your work situation? Overall, how satisfied are you with your mental health? Overall, how satisfied are you with your physical health? Overall, how anxious did you feel yesterday? Overall, how happy did you feel yesterday? Table 1: List of Items for Factor Analysis. We must therefore recode this variable to ensure that high score indicates a positive response. This is because all variables except Variable 2 are positively worded. However, the scoring system does not reflect it. Looking at the six statements in Table 1 below, it is evident that one statement has been negatively worded.
