Percentage Change in Sales Analysis
Very Hard Data Analysis Interpretation Of Data
A data scientist is analyzing the sales performance of three different product categories (A, B, and C) over two quarters (Q1 and Q2) in the following table:
| Product Category | Q1 Sales | Q2 Sales |
|---|---|---|
| A | $40,000 | $50,000 |
| B | $30,000 | $60,000 |
| C | $50,000 | $40,000 |
Using this data, the data scientist calculates the percentage change in sales for each product from Q1 to Q2.
The percentage change in sales from one quarter to another is calculated using the formula:
Percentage Change = $$ rac{( ext{New Value} - ext{Old Value})}{ ext{Old Value}} imes 100$$
Based on this calculation, determine the relationships between the sales performance of the different categories across the two quarters.
