CLASSROOM TEST ANALYSIS

• CLASSROOM TEST ANALYSIS
• This program analyzes data consisting of one or more test scores. It can weight items differentially

The TOTAL output consists of three parts: A summary of statistics, a test frequency distribution, and a listing of students' scores. Any or all three parts of the output may be printed. The first part consists of a summary of the following test statistics: The number of items on the test, the mean, median, standard deviation, Kuder-Richardson reliability 21 (KR-21), standard error of measurement, the possible and obtained low and high scores, and the number of scores.

The second part of the TOTAL output displays a test frequency distribution. The raw scores are ordered from high to low, with the corresponding standard score, percentile rank, percentage of people in the total group tested who received the given score, the frequency, and the cumulative frequency. The accompanying histogram portrays the frequency of the scores at each score value.

The third part of the TOTAL output is a listing of the students, sorted alphabetically or by student number. The raw score, standard score, and percentile rank for each test, and optionally for the summed raw and/or standard scores, is presented for each student. If grades are based on an examination score distribution, the summed raw score distribution, or the summed standard score distribution, or determined by assigning a certain proportion of the class different letter grades, then the assigned grades can print out in the listing of individual scores. However, this method of assigning grades is not recommended.
