Analyzing Shopping App Sales Data
The question asks us to find the average number of clothes sold by a shopping app over three specific years: 2019, 2020, and 2021. To do this, we need to extract the sales figures for clothes from the provided table and then calculate the average.
Sales Data Overview
Let's look at the data presented in the table:
| Products | 2019 | 2020 | 2021 |
|---|---|---|---|
| Cloth | 824 | 476 | 500 |
| Electronics | 750 | 820 | 450 |
| Makeup | 660 | 810 | 510 |
| Footwear | 470 | 390 | 790 |
We are interested in the sales data for 'Cloth' across the three years.
- Clothes sold in 2019: 824
- Clothes sold in 2020: 476
- Clothes sold in 2021: 500
Calculating the Average Number of Clothes Sold
The average of a set of numbers is found by summing all the numbers in the set and then dividing by the count of numbers in the set. In this case, the numbers are the sales figures for clothes in the three years, and the count is 3 (for the years 2019, 2020, and 2021).
The formula for the average is:
$$ \text{Average} = \frac{\text{Sum of values}}{\text{Number of values}} $$
First, let's find the total number of clothes sold over the three years:
$$ \text{Total Clothes Sold} = \text{Sales in 2019} + \text{Sales in 2020} + \text{Sales in 2021} $$
$$ \text{Total Clothes Sold} = 824 + 476 + 500 $$
$$ \text{Total Clothes Sold} = 1300 + 500 $$
$$ \text{Total Clothes Sold} = 1800 $$
Now, we calculate the average number of clothes sold by dividing the total sales by the number of years (3):
$$ \text{Average Clothes Sold} = \frac{\text{Total Clothes Sold}}{\text{Number of Years}} $$
$$ \text{Average Clothes Sold} = \frac{1800}{3} $$
$$ \text{Average Clothes Sold} = 600 $$
The average number of clothes sold by the shopping app in all three years is 600.
Revision Table: Key Concepts
| Concept | Definition | How it applies here |
|---|---|---|
| Average | The sum of a set of values divided by the number of values. | Used to find the typical sales figure over the three years. |
| Sales Data | Numerical information about the quantity of products sold over a period. | The table provides the sales data for different products and years. |
| Summation | Adding a series of numbers together to find a total. | Used to find the total number of clothes sold across the three years. |
Additional Information: Analyzing Sales Trends
Analyzing sales data like this helps businesses understand performance over time. While the average gives a central value, looking at individual year data (824, 476, 500) shows fluctuations. Sales were high in 2019, dropped significantly in 2020, and then recovered somewhat in 2021. Understanding these trends can help the shopping app make informed decisions about inventory, marketing, or strategy.
Calculating averages is a fundamental skill used in many areas, including finance, statistics, and everyday problem-solving.
