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 'whole' 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. In the determination of the average of past numeric grades, the calculator allows the entry of the grades and computes the average of the grades. The calculator keeps a list of the grades in memory for easy editing and constantly updates the display with a new grade average as grades are added or deleted form the list. Other preferred embodiments of the calculator offer calculating, and calculating and/or clock/timer/alarm mode functions. The user can scroll up and down respective grade lists in the Grading and Averaging Modes of the invention.
