To solve the questions based on the provided information about communication technology and the data in TABLE 1, we will follow the steps outlined below. However, since the actual data from TABLE 1 is not provided, I will guide you on how to approach each question based on typical data analysis methods.

### 1.1 Explain why some data in the table is categorical.

**Explanation:**
Categorical data refers to data that can be divided into specific categories or groups that do not have a numerical value. In the context of TABLE 1, the data that describes types of communication (e.g., cellphone, Internet, social networks) is categorical because it classifies the population based on the means of communication they use rather than measuring a quantity. For example, the categories might include "high usage," "medium usage," and "low usage," which do not represent numerical values but rather qualitative distinctions.

### 1.2 Write down the modal percentage usage for cellphone communication.

**Approach:**
To find the modal percentage usage for cellphone communication, you would look for the percentage that appears most frequently in the data for cellphone usage across the different regions. If the data were available, you would identify the highest frequency percentage.

### 1.3 Calculate the median percentage usage for Internet communication.

**Approach:**
To calculate the median percentage usage for Internet communication:
1. List all the percentages for Internet usage in ascending order.
2. If there is an odd number of values, the median is the middle value. If there is an even number of values, the median is the average of the two middle values.

### 1.4 Write down the total percentage of Internet usage in America.

**Approach:**
To find the total percentage of Internet usage in America, you would look at the specific data point for America in TABLE 1 and note the percentage listed for Internet usage.

### 1.5 Determine the total percentage of the world population living in all of the regions.

**Approach:**
To determine the total percentage of the world population living in all regions, you would sum the percentages of the population for each of the 12 regions listed in TABLE 1. The total should ideally equal 100% if all regions are accounted for.

### 1.6 Write down the global region that shows the greatest difference between the percentage usage of Internet communication and the percentage usage of cellphone communication.

**Approach:**
To find the region with the greatest difference:
1. Calculate the difference between the percentage of Internet communication and cellphone communication for each region.
2. Identify the region with the largest difference.

### Conclusion
To answer these questions accurately, you would need to refer to the specific data in TABLE 1. If you can provide the data from TABLE 1, I can assist you further with the calculations and specific answers.
To answer these questions, refer to the data in TABLE 1.
