Psychological testing

Thanks for your efforts to add to the article. Some of your sentence structure is very difficult to follow. For example, "It is important that differences between the chance of people having an item correct only depends on differences between those people on the construct that is measured". The phrase "differences between the chance of people having an item correct" is especially problematic. I think I get the general idea of what you mean by the last half of the sentence, but the first part, frankly, is incomprehensible. Please take that as an effort to improve the article, not a personal attack. I'm an expert on testing (but, of course, credentials mean nothing on Wikipedia), but I really find the sentence very difficult to understand.

Also, I haven't taken the time yet to look at the source from SPA, but some of the phrasing sounds very familiar. Is it a direct quote? Maybe my memory is faulty. Thanks. Cresix (talk) 23:42, 1 December 2010 (UTC)

Hi. I think it may well be better if you discuss the changes you want to make on the talkpage first as you seem to be removing established information and replacing it with some material which is hard to understand. I am also adding some handy links below in a "welcome" template. Cheers. Fainites ^barleyscribs 00:15, 2 December 2010 (UTC)

Hi. Sorry if I misunderstood. I thought I was just changing the stuff about the red card. By the way - don't forget to put four of these things ~ called tildas after your posts on talkpages.

More concerns

Please give these issues some thought. I'm not asking for immediate changes, but I am concerned that the article has some misleading (if not inaccurate) information:

1. "psychological tests ask for a respondent's maximum performance whereas a questionnaire asks for the respondent's typical performance": Not all psych tests ask for maximum performance, only those that measure areas related to ability. For example, personality tests do not ask for "maximum performance"; how does one provide maximum performance on the MMPI-2? As another example, interest inventories do not seek information about performance.
2. "It is important that people that are equal on the measured construct also have an equal probability of answering the test items correctly": Here again, this statement addresses only tests related to abilities. The problematic word here is "correctly". We don't typically think of giving "correct" responses to personality tests, unless you consider nonpathological responses "correct", but I don't think that's what you're referring to.
3. The mathematics/soccer example is difficult to understand, especially for someone who is not familiar with soccer. The phrase "how much players" also is awkward. You might want to find a completely different example.
