The score of a student getting 70 correct and 30 incorrect in True/False item by applying guessing correction formula will be?
درست/غلط آئٹم میں 70 درست اور 30 غلط حاصل کرنے والے طالب علم کا اندازہ درست کرنے کے فارمولے کو لاگو کر کے اسکور کیا ہوگا؟
Explanation
To apply the guessing correction formula for True/False items, we need to know the number of options (N). In True/False items, there are typically 2 options (True or False).
Given:
Number of correct answers (R) = 70
Number of incorrect answers (W) = 30
Number of options (N) = 2
Using the guessing correction formula:
S=R−(W/N−1)
Substituting the values:
S=70−(30/2−1)
S= 70 − 30= 40
So, the score of a student getting 70 correct and 30 incorrect in a True/False item, by applying the guessing correction formula, will be 40. Therefore, the correct option is 40.
