The sum of 6 numbers is 348. Find their average.
Appeared in: DSSSB 13 August 2024
Explanation
- The average, or arithmetic mean, is a measure of central tendency.
- It is calculated by dividing the total sum of a set of values by the number of values in that set.
- In this case, the sum is 348 and the number of values is 6.
- The calculation is 348 ÷ 6, which equals 58.
Why Other Options Were Wrong
- Option B: This value would result from an incorrect division of 348 by 6. It is a calculation error.
- Option C: This is another calculation error. 348 divided by 6 is exactly 58.
- Option D: This value is also a result of a miscalculation.

Clinical Relevance
- Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Calculation of Arithmetic Mean (Average) as background academic context rather than a clinical decision trigger.
- Basic mathematical skills are fundamental in nursing for accurate medication dosage calculations, which is critical for patient safety.
- Nurses use averages to interpret trends in patient data, such as the average heart rate over an hour, mean arterial pressure (MAP), or average blood glucose levels over several days.
- Understanding averages is also essential for interpreting research findings and applying evidence-based practice at the bedside.
How to Approach the Question
- First, identify the key information provided in the question: the sum of the numbers (348) and the count of the numbers (6).
- Recall the formula for calculating the average (arithmetic mean): Average = Sum of values / Count of values.
- Substitute the given values into the formula: Average = 348 / 6.
- Perform the division to find the result.
- Compare your calculated result with the given options to select the correct answer.
