Answer
Explanation:
Step1: Count data - points
There are 2 + 2+1 + 4+1 + 2=12 data - points.
Step2: Determine median position
Since (n = 12) (an even number), the median is the average of the (\frac{n}{2})th and ((\frac{n}{2}+ 1))th ordered data - points. (\frac{n}{2}=\frac{12}{2}=6) and (\frac{n}{2}+1 = 7).
Step3: Order data and find median
Ordering the data by the number of letters: 4, 4, 6, 6, 7, 8, 8, 8, 8, 9, 10, 10. The 6th value is 8 and the 7th value is 8. The median is (\frac{8 + 8}{2}=8).
Answer:
8
