calculating cumulative frequency

in theory (practically speaking it would never happen) if the scores were evenly distributed then and only then would the cumulative frequency be equal to the score percentage, therefore in the example given the cumulative frequency would be 60% and it is not one of the possibilities of the test... As Bruce said a graph must/should have been included as a compilation of all the scores. |

and, no, even a Normal distribution is useless unless we know the mean and standard deviation. Bruce |
