Find the median of the data. 21, 15, 6, 25, 18, 13, 20, 9, 8, 12.

Answer:

Arranging in ascending order: 6, 8, 9, 12, 13, 15, 18, 20, 21, 25 Since number of observations is even, the median is given by finding the average or mean of the two middle most observations: So, median =\[\frac{13+15\text{ }}{2}=\frac{28}{2}\text{=14}\]
