ایک سے زیادہ انتخابی سوال کے آئٹم میں 70 درست اور 30 غلط جوابات حاصل کرنے والے طالب علم کا اسکور کیا ہوگا؟
Explanation
To apply the guessing correction formula for Multiple Choice Questions (MCQs), we need to know the number of options (N). In MCQ items with four options, there are typically 4 options to choose from.
Given:
Number of correct answers (R) = 70
Number of incorrect answers (W) = 30
Number of options (N) = 4
Using the guessing correction formula:
S=R−(W/N−1)
Substituting the values:
S=70−(30/4−1)
S=70−(30/3)
S= 70 − 10= 60
So, the score of a student getting 70 correct and 30 incorrect answers in an MCQ item with four options, by applying the guessing correction formula, will be 60. Therefore, the correct option is 60.
