Given the limited number of items that can be included on a test or inventory, test developers must often make difficult decisions regarding the proportion of items that can be used to assess each dimension of a construct. For each of the following multidimensional tests, determine the proportion of items you would choose to assess each of the specified dimensions. For each test, ensure the total proportion of items sums to 100% across dimensions. Justify your determination for each test.
