Question

Scott, living in Alabama, took voltage measurements on random days from the generator attached to him home, as well as the electricity directly coming into him home. Scott then arranged that data into a boxplot, as displayed here:

Generator Voltage Home Voltage 121 122 Voltage (volts) 123

1. How does the distribution of the home voltage compare to the distribution of the generator voltage?

2. How do the 5-number summaries compare to one another?

3. If you were the homeowner, what would be the most important observation you could make about the difference between the home voltage and the generator voltage?

Answer 1

1. Home voltage - Data is less spread compared to Generator Voltage

Generator voltage median is higher than Home Voltage.

2 All five summary that minimum,Q1,Q2,Q3 and maximum values are less than Generator five number summary.

3. Home voltage is approximately Symmetric while the data of Generator voltage is Right skewed. Including part2 answer too.
