Question

what is the median? 1,2,3,4 3 2 2 and 3 2.5

Explanation:

Step1: Check number of data - points

There are 4 data - points (even number).

Step2: Arrange in ascending order

The data is already in ascending order: 1, 2, 3, 4.

Step3: Find middle positions

For an even - numbered data set of size $n = 4$, the middle positions are $\frac{n}{2}=2$ and $\frac{n}{2}+1 = 3$.

Step4: Calculate median

The values at these positions are 2 and 3. Median=$\frac{2 + 3}{2}=2.5$.

Answer:

2.5
