Equivalent Forms |
If you wanted to evaluate the reliability of a critical thinking assessment in philosophy, you might create a large set of items that all pertain to critical thinking and then randomly split the questions up into two sets (forms A and B), which would represent the equivalent forms. One group of students gets form "A" first, then "B". Another group takes the "B" form of the test first, then the "A" version. The scores on both are then correlated, producing a correlation or reliability coefficient.
