Answer
## Step1: Arranging the data set in ascending order, we get: 3.40, 15.28## Step2: Since there are only two numbers, the median is the average of these two numbers. ###
## Step3: The mean is also the average of these two numbers. ###
After performing the calculations, we find that the median and mean of the data set are both 9.34.
Explanation
## Step1: First, we need to arrange the data set in ascending order. ## Step2: To find the median, we need to locate the middle number. If the data set has an odd number of observations, the middle one is the median. If there is an even number of observations, the median is the average of the two middle numbers.## Step3: To find the mean, we add up all the numbers and then divide by the number of numbers.
