Answer :
The sample median of the number of runs is 15.
What is a median of a sample?
Median is one of the measures of central tendency. It is the middle value of the sample. It may be both, either in ascending or in descending order.
To find the median of the sample, the first step is to arrange the data, either in the ascending order or in the descending order. Since the given data is not already arranged, we have to first arrange the data in order to find the median.
11.1, 14.5, 14.8, 15.2, 16.0, 19.7
The given data is now arranged in ascending order.
We get the central values in the sample as 14.8 and 15.2.
The median is the central value of these two figures
Average= 14.8+15.2/2= 15
Thus the median is 15.
