What is a graph?

  1. A diagram showing the relationship between two or more variables.

  2. A mathematical equation that describes a relationship between two or more variables.

  3. A table of data showing the values of two or more variables.

  4. A chart that shows the distribution of data.


Correct Option: A
Explanation:

A graph is a visual representation of the relationship between two or more variables. It is used to show how the variables are related to each other and to identify trends or patterns in the data.

What are the two main types of graphs?

  1. Line graphs and bar graphs.

  2. Scatter plots and histograms.

  3. Pie charts and Venn diagrams.

  4. Flowcharts and organizational charts.


Correct Option: A
Explanation:

The two main types of graphs are line graphs and bar graphs. Line graphs are used to show how a variable changes over time, while bar graphs are used to compare different categories of data.

What is a line graph?

  1. A graph that shows the relationship between two variables using a line.

  2. A graph that shows the distribution of data using a line.

  3. A graph that shows the relationship between two variables using a bar.

  4. A graph that shows the distribution of data using a bar.


Correct Option: A
Explanation:

A line graph is a graph that shows the relationship between two variables using a line. The line is plotted on a coordinate plane, with the independent variable on the x-axis and the dependent variable on the y-axis.

What is a bar graph?

  1. A graph that shows the relationship between two variables using a bar.

  2. A graph that shows the distribution of data using a bar.

  3. A graph that shows the relationship between two variables using a line.

  4. A graph that shows the distribution of data using a line.


Correct Option: A
Explanation:

A bar graph is a graph that shows the relationship between two variables using a bar. The bars are plotted on a coordinate plane, with the independent variable on the x-axis and the dependent variable on the y-axis.

What is a scatter plot?

  1. A graph that shows the relationship between two variables using a line.

  2. A graph that shows the distribution of data using a line.

  3. A graph that shows the relationship between two variables using a bar.

  4. A graph that shows the distribution of data using a bar.


Correct Option: A
Explanation:

A scatter plot is a graph that shows the relationship between two variables using a line. The line is plotted on a coordinate plane, with the independent variable on the x-axis and the dependent variable on the y-axis.

What is a histogram?

  1. A graph that shows the distribution of data using a bar.

  2. A graph that shows the relationship between two variables using a bar.

  3. A graph that shows the distribution of data using a line.

  4. A graph that shows the relationship between two variables using a line.


Correct Option: A
Explanation:

A histogram is a graph that shows the distribution of data using a bar. The bars are plotted on a coordinate plane, with the independent variable on the x-axis and the frequency of the data on the y-axis.

What is a pie chart?

  1. A graph that shows the distribution of data using a circle.

  2. A graph that shows the relationship between two variables using a circle.

  3. A graph that shows the distribution of data using a bar.

  4. A graph that shows the relationship between two variables using a bar.


Correct Option: A
Explanation:

A pie chart is a graph that shows the distribution of data using a circle. The circle is divided into sectors, with each sector representing a category of data. The size of each sector is proportional to the frequency of the data in that category.

What is a Venn diagram?

  1. A graph that shows the relationship between two or more sets using circles.

  2. A graph that shows the distribution of data using a circle.

  3. A graph that shows the relationship between two or more sets using a bar.

  4. A graph that shows the distribution of data using a bar.


Correct Option: A
Explanation:

A Venn diagram is a graph that shows the relationship between two or more sets using circles. The circles are drawn on a coordinate plane, and the sets are represented by the areas inside the circles. The intersection of the circles represents the elements that are common to both sets.

What is a flowchart?

  1. A diagram that shows the steps in a process.

  2. A graph that shows the relationship between two or more variables.

  3. A graph that shows the distribution of data.

  4. A graph that shows the relationship between two or more sets.


Correct Option: A
Explanation:

A flowchart is a diagram that shows the steps in a process. It is used to visualize the flow of data or control in a system.

What is an organizational chart?

  1. A diagram that shows the structure of an organization.

  2. A graph that shows the relationship between two or more variables.

  3. A graph that shows the distribution of data.

  4. A graph that shows the relationship between two or more sets.


Correct Option: A
Explanation:

An organizational chart is a diagram that shows the structure of an organization. It is used to show the relationships between different positions and departments within the organization.
