Answer
Explanation:
Step1: Count data - points
There are 3 points at 0, 1 point at 1, 5 points at 2, 4 points at 3, 1 point at 4, and 6 points at 5. The total number of data - points is (3 + 1+5 + 4+1 + 6=20).
Step2: Find the median position
Since (n = 20) (an even - numbered data set), the median position is (\frac{n}{2}=10) and (\frac{n}{2}+1 = 11).
Step3: Order and find the middle values
Ordering the data by the number of assignments, we list out the values based on the frequency. The 10th and 11th values fall within the group of 2.
