Question

The Standard percentile value taken for fixing the variability of human characteristics is

• A. 80superscript{th} percentile
• B. 85superscript{th} percentile
• C. 90superscript{th} percentile
• D. 95superscript{th} percentile

Hint:

- The 5superscript{th} percentile is often used for minimum design considerations. - The 50superscript{th} percentile represents the median or average. - The 95superscript{th} percentile is preferred for ensuring broad accommodation in ergonomic designs.

Answer 1

The Correct Option is D

Step 1: Standard percentiles are used in anthropometric data analysis to account for variability in human characteristics such as height, weight, and reach. Step 2: The 95superscript{th} percentile is commonly used in ergonomic design to accommodate most of the population while ensuring inclusivity. Step 3: This means that 95\% of the population falls within the given range, making it a widely accepted standard for safety, usability, and comfort. Thus, the correct answer is (D) 95superscript{th} percentile.
