Graphical Representation

A frequency table shows:

• the distribution of data values

• the relationship between two variables

• the average of a data set

• the range of a data set

A line graph is used to:

• show trends over time

• compare different categories

• display parts of a whole

• illustrate a process

A bar chart represents:

• a) Numerical data using bars

• b) A type of line graph

• c) A circular statistical graphic

• d) A method to display text data

The purpose of a pie chart is to:

• show trends over time

• compare quantities

• display parts of a whole

• illustrate relationships between variables

A scatter diagram represents:

• a relationship between two variables

• a distribution of a single variable

• a sequence of events over time

• a comparison of multiple categories

A histogram is used for:

• Displaying the distribution of data

• Calculating the mean of data

• Finding the median of data

• Sorting data in ascending order

When constructing tables, charts, graphs, and distribution curves, you should include:

• Titles and labels

• Random data

• Unrelated images

• Personal opinions
