The maze adjusted score is calculated using a specific formula designed to account for the possibility of guessing. It modifies the raw score by penalizing incorrect answers.
Understanding the Maze Adjusted Score
The adjusted score, often used in assessments like timed maze tasks or multiple-choice tests, provides a more accurate reflection of a student's knowledge or ability than simply counting correct answers. Its primary purpose is to compensate for random guessing, making it less advantageous to guess on items a student is unsure about.
This calculation is based on a standard Adjusted Score formula.
The Formula for Adjusted Score
Based on the provided information, the Adjusted Score is calculated using the following formula:
Adjusted Score = number of correct responses – (number of incorrect responses ÷ 2)
Components of the Formula
- Number of correct responses: This is the total count of items the student answered correctly.
- Number of incorrect responses: This is the total count of items the student answered incorrectly. Unanswered items are typically not counted as incorrect in this formula.
How the Adjustment Works
The formula applies a penalty for incorrect responses. By dividing the number of incorrect responses by two (assuming, for example, a multiple-choice format where a random guess has a 1 in 2 chance of being correct, although the divisor can vary depending on the test format and guessing probability), it effectively subtracts points for errors. This penalization discourages random guessing, as incorrect guesses reduce the overall score.
Example Calculation
Let's say a student completes a maze task or test and achieves the following results:
- Number of correct responses: 25
- Number of incorrect responses: 10
- Number of unanswered items: 5
Using the formula:
- Identify the number of correct responses: 25
- Identify the number of incorrect responses: 10
- Apply the formula:
Adjusted Score = 25 – (10 ÷ 2)
Adjusted Score = 25 – 5
Adjusted Score = 20
In this example, the student's maze adjusted score would be 20. This is lower than their raw score of 25 correct responses, reflecting the penalty for incorrect answers.
