Questions & Answers

Q: What are the four commodities involved in the billing analysis?

The four commodities in the billing analysis are landline phone, electricity, laundry, and mobile phone. These bills are tracked for three individuals—Ravi, Dev, and Manu—across five months, allowing for comparative analysis and budgeting insights through a Tableau visualization.

Q: How do you calculate the total bill paid by Dev in June?

To find Dev's total bill in June, sum all individual bill amounts for the commodities: landline (123), electricity (150), laundry (324), and mobile phone (134). Adding these amounts together results in a total of 731 rupees, which is identified as option C in the analysis.

Q: What formula is used to determine the average electricity bill paid by Manu?

The average is calculated using the formula: average = sum of observations / number of observations. For Manu’s electricity bills over five months (315, 135, 98, 116, and 131), the total is 795, which is then divided by 5 to yield an average of 159 rupees, indicating option C as the correct answer.

Q: What is the significance of identifying second highest and lowest bills?

Identifying the second highest mobile phone bill and the lowest electricity bill is crucial for understanding spending trends. This analysis helps to highlight areas where costs can be reduced or managed better, showcasing the importance of careful observation over complicated calculations in data analysis.
