Answer:
The correct statement is C.
Step-by-step explanation:
A boxplot, also known as a box and whisker plot is a method to demonstrate the distribution of a data-set based on the following 5 number summary,
1. Minimum (shown towards the left of the chart)
2. First Quartile (shown by the left-most line of the box)
3. Median (or the second quartile) (shown as a line in the center of the box)
4. Third Quartile (shown by the right-most line of the box)
5. Maximum (shown towards the right of the chart).
From the provided box plot it can be concluded that:
- Minimum = 3
- First Quartile = 6
- Median = 9
- Third Quartile = 12
- Maximum = 15
The median is a quantity in statistics that points out where the mid-value of a data set is. Half of the data is less than the median and half is more than the median.
The median is 9, i.e. half of the data is less than 9 and half is more than 9.
The correct statement is C.
