Abstract:
A grade list and averaging, hand-held calculator is disclosed for use by teachers and others in quickly determining the numeric grade of a test-exam, or equal parts constituting a âwholeâ to be analyzed, and the average of past numeric grades. In the determination of the numeric grade of a test-exam, for example, the calculator allows the entry of the total number of problems on the test, and, corresponding to this total number of problems, displays first and additional lists of potential numeric percentage grades correlating to respective first and additional ranges of problems wrong within the original number of problems on a test entered into the calculator. Each of the first and additional lists are displayed simultaneously as multiple numeric grades, one after the other on the display of the calculator. In one embodiment, ten potential grades are viewed simultaneously. The teacher can quickly scroll through the list of grades and corresponding range of problems wrong, and determine the actual grade by correlating one of the range of problems wrong with its corresponding simultaneously presented numeric percentage grade in the list of grades displayed.
