If anyone could be bothered helping me out with 4 definitions relating to psychology/statistics I would be so, so very grateful. I have searched and searched google and cannot find definitions for the following- Rule of assignment, Permissible transformations, Permissible arithmetic operations, Permissible statistics. I have a very vague idea of what they mean but would LOVE to have some working definitions.
