(this is why i think ANOVAs are useless because you always end up doing the contrasts anyway, so why not just do them from the start, but that's another story, courses always teach ANOVA and you will always have to learn ANOVA). I assume that you will already know how to define variablesandvalues, howto toggle between the numerical expression and verbal descriptor of the values (i.e., you can make SPSS show responses as strongly agree/agree/disagree/strongly disagree or as 1/2/3/4), and how to key in data.

What is the most effective way to run internal consistency? COMPUTE x2 = 1.5 * x1 - 0.5 . I am very confused since I could not find an understandable answer for it: (4 - 1) * (x - 1) / (5 - 1) + 1 = 3 * (x - 1) / 4 + 1 = (3/4) * x - (3/4) + 1 = (3/4) * x + (1/4) wikiHow is a wiki, similar to Wikipedia, which means that many of our articles are co-written by multiple authors. (6/4) * x - (6/4) + 1 Data may also be combined into say two nominal categories Agree/Accept and Disagree/Reject, which allows us to carry out the; Chi-square test. This will be in numerical form (1, 2, 3, ), but you can change it to a verbal descriptor for consistency (Figure 3).
