True False | MCQs

Explanation

The most significant advantage of true/false items is wide sampling.

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.

Explanation

True or false items cannot provide accurate criterion of evaluation because:

• They do not require thorough study to attempt.
• Chance of guessing on the part of examinees is at the highest probability.
• They generally inflate actual scores due to guessing or cheating.
