Calculate the median from the following values 1.9,1.9, 1.9, 2.1, 2.4, 2.5, 2.5, 2.9 –
**Core Concept**
When calculating the median, we need to arrange the data in ascending order and find the middle value. If there are an even number of values, the median is the average of the two middle values.
**Why the Correct Answer is Right**
To find the median, we first arrange the given values in ascending order: 1.9, 1.9, 1.9, 2.1, 2.4, 2.5, 2.5, 2.9. Since there are 8 values (an even number), the median will be the average of the two middle values, which are the 4th and 5th values: 2.1 and 2.4. To calculate the median, we find the average of these two values: (2.1 + 2.4) / 2 = 2.25.

**Clinical Pearl / High-Yield Fact**
When calculating the median, make sure to arrange the data in ascending order and find the middle value(s). If there are an even number of values, the median is the average of the two middle values.
