Statistics: Median

| Mean Temperature (C°) | Number of Days | |-----------------------|----------------| | 29 | 5 | | 30 | 11 | | 31 | 8 | | 32 | 6 | The table displays the mean daily temperatures in the Tokharian desert for thirty days in a certain month. What is the median temperature in that particular month?

Incorrect. [[snippet]] This is a trap option.
Correct. [[snippet]] 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.
