Match the List-I with List-II:

Correct option is C

The correct matching is:

• A-III (T-score): T-scores are standardized scores with a mean of 50 and a standard deviation (SD) of 10, used frequently in psychological assessments.
• B-I (Percentile): Percentiles rank scores relative to a larger group, showing the percentage of scores below a particular value.
• C-II (Z-score): Z-scores standardize the unit of measurement by expressing a score in terms of standard deviations from the mean, with a mean of 0 and SD of 1.
• D-IV (Standard score): Standard scores help compare an individual's performance with a reference group, allowing a direct comparison irrespective of different units or tests.

Information Booster:

1. T-scores are often used in psychological testing, particularly in aptitude and achievement tests.
2. Z-scores indicate how far a data point is from the mean in terms of standard deviation and are key in statistical analysis.
3. Percentiles are essential in understanding relative standing in a group, such as ranking in standardized tests.
4. Standard scores normalize scores across different tests or measures to enable fair comparisons.
