Question

johns sales for his last eight shifts are shown in the table below. what is the median of those sales? sales $800.00 $1,000.00 $600.00 $1,300.00 $650.00 $1,550.00 $650.00 $600.00 a. $600.00 b. $650.00 c. $725.00 d. $950.00

Explanation:

Step1: Arrange data in ascending order

$600, 600, 650, 650, 800, 1000, 1300, 1550$

Step2: Determine position for median

Since $n = 8$ (even number of data - points), median is average of $\frac{n}{2}$ - th and $(\frac{n}{2}+1)$ - th ordered data - points. $\frac{n}{2}=\frac{8}{2}=4$ and $\frac{n}{2}+1 = 5$.

Step3: Calculate median

Median=$\frac{650 + 800}{2}=\frac{1450}{2}=725$

Answer:

C. $725.00$
