Frequency Tables & coordinate plane

Front

What is a frequency table?

Back

A frequency table is a way to organize data that shows how often each value occurs in a dataset.

Front

What is a two-way frequency table?

Back

A two-way frequency table displays data that summarizes the relationship between two categorical variables.

Front

How do you calculate relative frequency?

Back

Relative frequency is calculated by dividing the frequency of a specific category by the total number of observations.

Front

What does the grand total represent in a frequency table?

Back

The grand total is the sum of all frequencies in the table, representing the total number of observations.

Front

What is the purpose of a coordinate plane?

Back

A coordinate plane is used to graph points, lines, and shapes using a pair of numerical coordinates.

Front

What are the axes of a coordinate plane?

Back

The axes of a coordinate plane are the horizontal axis (x-axis) and the vertical axis (y-axis).

Front

How do you plot a point on a coordinate plane?

Back

To plot a point, identify its coordinates (x, y) and move x units along the x-axis and y units along the y-axis.

Front

What is the difference between categorical and numerical data?

Back

Categorical data represents categories or groups, while numerical data represents measurable quantities.

Front

What is a mode in a dataset?

Back

The mode is the value that appears most frequently in a dataset.

Front

What is a median in a dataset?

Back

The median is the middle value when the data is arranged in ascending order.
