Answer:
0.236
Explanation:
The data is as follows:
0.264, 0.211, 0.199, 0.236, 0.283, 0.257, 0.225.
First of all,the median of a set of numbers is the number that, occurs in the middle, if the numbers are arranged in ascending or descending order of magnitude.
We now order the numbers:
0.199,0.211, 0.225, 0.236,0.257, 0.264, 0.283
The number appearing at the middle is 0.236
Hence the median is 0.236
Note:In a situation where two numbers appear in the middle, the median is calculated by finding the mean of these two numbers (i. e add the two numbers and divide by 2)
