this table shows the area in inches of four rectangular scraps of fabric. what is the median of the sizes of the four scraps of fabric? scrap area (in²) a 84 b 72 c 80 d 84
Answer
Explanation:
Step1: Arrange data in ascending order
72, 80, 84, 84
Step2: Find the median for even - numbered data
Since there are 4 data points, the median is the average of the 2nd and 3rd ordered values. Median=$\frac{80 + 84}{2}$
Step3: Calculate the average
$\frac{80+84}{2}=\frac{164}{2}=82$
Answer:
82 in²
