Median of 1, 6, 2, 5, 4, 3:
Options:
(a) 2
(b) 2.5
(c) 3
(d) 3.5
✅ Correct Answer:
(d) 3.5
Explanation:
Median is the middle value in an ordered dataset. To find it, we first arrange the numbers in ascending order:
1, 2, 3, 4, 5, 6
Since there are 6 numbers (even count), the median is the average of the 3rd and 4th numbers:
3 + 4 = 7 → 7 ÷ 2 = 3.5
Median is a measure of central tendency, indicating the midpoint of data, less affected by extreme values compared to the mean. In statistics and educational measurement, median is often used to report performance distributions when data has outliers.
10 Related Facts:
- Median divides data into two equal halves.
- For odd numbers of observations, it is the middle value.
- For even numbers, it is the average of middle two values.
- Median is resistant to outliers.
- Different from mean and mode.
- Used in educational assessment reporting.
- Helps interpret class performance.
- Measures central tendency.
- Often used in PPSC quantitative questions.
- Useful in descriptive statistics of exam scores.
