Decide where the middle value lies by dividing the sum of frequencies by 2.
>$$\text{Place value} = \frac{5 + 11 + 8 + 6}{2} = \frac{30}{ 2} = 15$$.
This set has an even number of elements (30), so we need to find the average of the 15th and 16th elements of the set to find the median. Then count from the top till you reach these elements.
In this case, the temperature on both the 15th and 16th day was 30°. Hence 30° is the median.
