This understanding will guide the selection of the most appropriate graph type and ensure that the visualization accurately represents the data.

B. Discuss the types of data suitable for a graph with 2 variables
• Numeric data: Graphs with 2 numerical variables, such as age and income, can be effectively represented using scatter plots or line graphs.

• Categorical data: When one variable is categorical, such as gender or city, and the other is numerical, bar graphs or pie charts can be used to visualize the relationship.

• Time series data: If one of the variables represents time, line graphs are the most suitable for visualizing the relationship between the two variables over time.

## Choosing the right graph type

When visualizing data in Excel, it's important to select the right graph type to effectively communicate the relationship between two variables. Let's compare and contrast different graph types to understand their strengths and weaknesses.

A. Compare and contrast different graph types
• ### Scatter plot

A scatter plot is used to display the relationship between two continuous variables. It is ideal for identifying patterns or trends in the data and determining if there is a correlation between the variables.

• ### Line graph

A line graph is also used to show the relationship between two variables over time or to demonstrate trends. It is particularly effective for displaying changes or trends in the data over a continuous period.

B. Explain which graph type is best for visualizing 2 variable data

When visualizing 2 variable data in Excel, the best graph type to use largely depends on the nature of the data and the insights you want to convey. If you want to show the relationship between two continuous variables and identify any potential correlation, a scatter plot would be the most suitable option. On the other hand, if you want to demonstrate changes or trends in the data over time, a line graph would be more appropriate. It's important to consider the specific characteristics of your data and the message you want to convey when choosing the right graph type.

## Data input and formatting

When creating a graph in Excel with 2 variables, it is crucial to input the data correctly and format it appropriately to ensure that the graph accurately represents the relationship between the variables.

A. Guide on how to input the data into Excel for creating the graph

1. Open a new Excel spreadsheet and enter the data for the two variables in separate columns.

2. Ensure that the data is organized in a clear and logical manner, with the independent variable (e.g., time, temperature) in one column and the dependent variable (e.g., sales, profit) in the other.

3. Double-check the accuracy of the data input to avoid any discrepancies in the graph.

B. Discuss the formatting options available in Excel to enhance the graph

Excel offers a range of formatting options to customize the appearance of your graph and make it more visually appealing and easy to interpret.

### 1. Chart styles and layouts

Explore the various chart styles and layouts available in Excel to find the most suitable option for displaying your data. Consider factors such as color schemes, fonts, and data labels to enhance the overall presentation of the graph.

### 2. Axis labels and titles

Adding descriptive and informative axis labels and a clear title to your graph can help provide context and understanding of the relationship between the two variables. Make use of Excel's formatting tools to customize the appearance of the labels and title to complement the graph.

### 3. Data markers and lines

Utilize data markers and lines to highlight specific data points or trends within the graph. Excel allows you to customize the appearance and style of these markers and lines to effectively convey the relationship between the variables.

By following these guidelines for data input and formatting in Excel, you can create a visually appealing and informative graph that effectively represents the relationship between two variables.
