Front

What is a dot plot?

Back

A dot plot is a statistical chart that consists of data points plotted on a simple scale, where each dot represents one data point.

Front

How do you find the number of data points in a specific range on a dot plot?

Back

Count the number of dots that fall within the specified range on the plot.

What is a bar graph?

Back

A bar graph is a visual representation of data using bars of different heights or lengths to show the frequency or value of different categories.

How do you calculate the total points earned from correct answers in a quiz?

Back

Multiply the number of correct answers by the points each answer is worth.

Front

What is a stem-and-leaf plot?

Back

A stem-and-leaf plot is a method of displaying quantitative data in a graphical format, similar to a histogram, where each data point is split into a 'stem' (the leading digit) and a 'leaf' (the trailing digit).

Front

How do you determine the range of a data set?

Back

The range is calculated by subtracting the smallest value from the largest value in the data set.

Front

What is a dot plot used for?

Back

A dot plot is used to display the frequency of data points in a small data set, making it easy to see patterns and trends.

Front

What does the height of a bar in a bar graph represent?

Back

The height of a bar represents the frequency or value of the category it represents.

Front

How can you compare two sets of data using a bar graph?

Back

You can compare two sets of data by placing their bars side by side for each category, allowing for easy visual comparison.

Front

What is the purpose of a stem-and-leaf plot?

Back

The purpose of a stem-and-leaf plot is to organize and display data while preserving the original data values.
