Subject: Re: reliability of bagrut exams
Dear Ziona,
If you cared to read what I wrote in my original note you could
possibly have saved yourself the trouble of commenting that
"this is not reliability".
In that note I referred readers to a quotation from an academic source:
http://www.georgetown.edu/departments/psychology/researchmethods/researchanddesign/validityandreliability.htm
Test/Retest Test/RetestTest/retest is the more conservative method to estimate
RELIABILITY. Simply put, the idea behind test/retest is that you should get the same score
on test 1 as you do on test 2. The three main components to this method are as follows: 1.)
implement your measurement instrument at two separate times for each subject;2). compute
the correlation between the two separate measurements; and3) assume there is no change in
the underlying condition (or trait you are trying to measure) between test 1 and test 2.
This means that if a students takes Moed A and gets 70 and then Moed B a month later and
gets 100, the meaning of these scores is that the test inNOT RELIABLE.Motti
