the data below shows the hours students studied per month for two classes:\nclass a:\nfind the median of class a. provide an answer accurate to the nearest tenth.
Answer
Explanation:
Step1: Count data - points
There are 4 + 3+ 1+ 4+ 2 = 14 data - points for Class A.
Step2: Determine position of median
Since (n = 14) (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{14}{2}=7) and (\frac{n}{2}+1 = 8).
Step3: Order data and find median
Ordering the data from the dot - plot: 0, 0, 0, 0, 4, 4, 4, 6, 8, 8, 8, 8, 10, 10. The 7th value is 4 and the 8th value is 6. The median is (\frac{4 + 6}{2}=5).
