Question

5 multiple choice 1 point hanna recorded the voltage drop across some resistors in her circuit, as shown in the table. what is the range and median of her data? resistor voltage drop (milliamps) 1 8.4 2 7.2 3 5.3 4 6.2 5 4.8 6 7.5 median: 6.2 ma range: 3.5 ma median: 6.7 ma range: 0.9 ma median: 6.7 ma range: 3.6 ma median: 7.2 ma range: 4.4 ma

Explanation:

Step1: Sort the data

$4.8, 5.3, 6.2, 7.2, 7.5, 8.4$

Step2: Calculate the median

Since there are 6 data - points (an even number), the median is the average of the 3rd and 4th ordered values. $\text{Median}=\frac{6.2 + 7.2}{2}=6.7$ mA

Step3: Calculate the range

The range is the difference between the maximum and minimum values. $\text{Range}=8.4−4.8 = 3.6$ mA

Answer:

Median: 6.7 mA
Range: 3.6 mA
