## How to Find the Median ### Method 1. Sort the numbers from smallest to largest 2. The median is the middle number For 3 values, the median equals the sum minus the minimum minus the maximum: **Median = a + b + c - min(a,b,c) - max(a,b,c)**
计算示例
Find the median of 7, 3, and 12.
- 01Sort the values: 3, 7, 12
- 02The middle value is 7
- 03Alternatively: 7 + 3 + 12 - min(3,7,12) - max(3,7,12) = 22 - 3 - 12 = 7
常见问题
What is the median?
The median is the middle value when numbers are arranged in order. For an odd count, it is the exact middle number. For an even count, it is the average of the two middle numbers.
When is the median better than the mean?
The median is more robust to outliers. For example, incomes of [30k, 35k, 40k, 45k, 1M] have a mean of $230k but a median of $40k, which better represents the typical value.
