Scanning & Scoring
The Testing Office provides to the University (faculty, staff, and students) the following services:
I. Scoring of objectively-scored classroom tests
Output includes the following:
- Alphabetical class listing with individual percentage scores, number of items right, wrong, omitted, and right minus 1/4 wrong.
- Item analysis with frequency of students selecting each response to an item; mean percent correct, mean percent wrong, percentage of students who responded correctly and incorrectly, point biserial correlation coefficient, and discrimination index.
- Grade distribution with mean and standard deviation, frequency and cumulative frequency of percentage scores and percentiles.
- Reliability measures with odd-even, first-half last-half, Kuder-Richardson Formula 20, and standard error of measurement.
- Graph of distribution of percentage scores.
- (Optional) Individual Student Reports which include instructor name, student name and identification number, number of items right, wrong, and omitted, listing of wrong items indicating student responses and keyed responses.
II. Summarizing Questionnaires/Surveys
Analysis of data includes frequency and percentage of each response for every item as well as a mean, standard deviation, and correlation for each item. An overall test mean and standard deviation is also listed. Information for each individual includes total score (for Likert scales), mean, and number omitted.
III. Transferring collected data from optical scanning forms to data files
Data collected on a large variety of optical scanning forms may be transferred in ASCII format to one or more of the following:
1. Attached data file to email, or
2. 3.5" floppy diskette - user must provide formatted diskette.
Information will be provided relative to the data record format.
The Testing Office utilizes both NCS Opscan 21 and 4XP scanners. Because not all types of forms are compatible with these machines, it is recommended that users confirm that forms to be used are, indeed, compatible. Two types of general purpose answer sheets which are compatible with the Testing Office hardware are available for purchase through the current GSU office vendors.
Turnaround time for the above services is normally one working day. Scan forms must be delivered to the Testing Office, Room 309, Counseling Center, during office hours (please do not use Interoffice mail service for sending forms). Office hours are 8:30 a.m. - 5:15 p.m., Monday - Friday.
Submittng Scan Forms:
1. Each submission should be placed in a large envelope with an instruction sheet taped to the outside of the envelope. Click here for a copy of the instruction sheet.
2. Each group of scan forms must have a key coded according to preferences. Examples can be obtained at the Testing Office. All scan forms should be arranged so that the tick marks are facing the same way.
3. If you wish to pick up the completed score reports yourself, please indicate that on the form and tell the person in the Testing Office to make a note of it in the log book. This will prevent confusion when Graduate Assistants pick up for an entire department.
