Given below are two statements, one labelled as Assertion (A) and the other labelled as Reason (R). Read the statements and choose the correct answer using the code given below.

Assertion (A): Standard score facilitates comparison of athlete’s performance in two different events having separate units.

Reason (R): The standard score indicates as to how many standard deviations a score is above or below the mean.

 Key Points

Assertion (A): Standard score facilitates comparison of athlete's performance in two different events having separate units.

• This statement asserts that the use of standard scores enables the comparison of an athlete's performance in two different events, even if those events have separate units of measurement.
• The standard score provides a standardized metric that allows for meaningful comparisons across different units.

Reason (R): The standard score indicates as to how many standard deviations a score is above or below the mean.

• This reason explains the concept of a standard score.
• It states that a standard score represents the number of standard deviations a score is either above or below the mean.
• In other words, it measures how much a particular score deviates from the average performance, expressed in terms of standard deviations.

Correct answer: Both (A) and (R) are true, and (R) is the correct explanation of (A).

According to the given options, the correct answer is that both the assertion (A) and the reason (R) are true, and the reason (R) provides the correct explanation for the assertion (A).

This means that the standard score indeed allows for the comparison of an athlete's performance in different events with separate units, and the reason explains that the standard score represents the number of standard deviations a score is above or below the mean.
