Types of Graphs

What is a Box Plot?

• A graphical representation of data using bars to show frequency.

• A standardized way of displaying the distribution of data based on a five-number summary: minimum, first quartile, median, third quartile, and maximum.

• A type of chart that shows the relationship between two variables.

• A method for calculating the average of a dataset.

How do you determine the most popular item from a graph?

• By identifying the lowest bar or point on the graph

• By identifying the highest bar or point on the graph, which indicates the greatest quantity or frequency.

• By averaging the values of all items on the graph

• By selecting the item with the most colors represented in the graph.

What is the purpose of a graph?

• To visually represent data to make it easier to understand, analyze, and interpret information.

• To create artistic representations of data without any specific purpose.

• To store data in a database for future reference.

• To replace written reports and eliminate the need for data analysis.

What does the Y-axis represent in a graph?

• The horizontal axis representing the independent variable.

• The vertical axis representing the dependent variable.

• The axis that shows the scale of the graph.

• The axis that represents time.

What is the difference between categorical and numerical data?

• Categorical data represents quantities or measurements, while numerical data represents categories or groups.

• Categorical data represents categories or groups, while numerical data represents quantities or measurements.

• Categorical data is always numerical, while numerical data is always categorical.

• There is no difference between categorical and numerical data.

What is a Bar Graph?

• A Bar Graph is a visual representation of data using bars of different heights or lengths to compare quantities across categories.

• A Bar Graph is a type of chart that displays data in a circular format.

• A Bar Graph is a method of organizing data in alphabetical order.

• A Bar Graph is a statistical tool used to calculate averages.

How can graphs help in making decisions?

• Graphs provide a visual summary of data, allowing for quick comparisons and insights into trends.

• Graphs are only useful for aesthetic purposes and do not aid in decision-making.

• Graphs can only show historical data and are not useful for future predictions.

• Graphs complicate the decision-making process by adding unnecessary information.

What is the significance of the scale on a graph?

• The scale on a graph indicates the range of values represented and helps in accurately interpreting the data.

• The scale on a graph is used to measure the height of the graph only.

• The scale on a graph determines the color of the graph lines.

• The scale on a graph is irrelevant to the data being presented.

What is a Histogram?

• A type of pie chart that shows the percentage of categories.

• A type of bar graph that represents the frequency distribution of numerical data, where the bars touch each other to indicate continuous data.

• A line graph that displays data points over time.

• A scatter plot that shows the relationship between two variables.

What does the X-axis represent in a graph?

• The vertical axis representing the dependent variable.

• The horizontal axis representing the independent variable.

• The axis that shows the scale of the graph.

• The axis that represents the average value of the data.
