You don't need to know the formulae cold but it will be a good idea to just understand the concepts and move on. Is there anywhere in the LOS where it was stated that you should calculate the chi-square stuff? It is more like demonstrate or discuss, if my memory serves me right.
If in doubt, use the LOS as a guide to study. |
