What representation would best display the data in the table?

The data is grouped by [tex]\(\square\)[/tex] so it would be best displayed in a [tex]\(\square\)[/tex].



Answer :

To determine the best way to display the data in the table, let's consider what kind of data we have and how it is organized.

The table presented shows the number of cell phones in millions for different countries. Here's a recap of the data:

- Russia: 230 million
- India: 750 million
- US: 290 million
- China: 650 million

The data consists of countries and their corresponding number of cell phones. This type of data involves categories (countries) and numerical values (number of cell phones), and it is grouped by a certain criterion.

When data is grouped by categories and we want to compare these categories based on their numerical values, a bar graph is often the best choice. This is because a bar graph clearly shows the comparisons between the different categories by using rectangular bars whose lengths are proportional to the values they represent.

### Step-by-Step Reasoning:

1. Identify the categories: The countries (Russia, India, US, China) are the categorical variables.
2. Identify the numerical values: The number of cell phones (in millions) for each country is the numerical variable.
3. Grouping criterion: The data in the table is grouped by countries.
4. Choose the best representation for comparison: A bar graph is suitable for comparing the values across different categories (countries in this case).

Therefore, the best way to display this data is by using a bar graph.

### Conclusion:
The data is grouped by country so it would be best displayed in a bar graph.
