Problem Solving with Dot Plots (Math TEKs 3.8A & 3.8B)

Front

What is a dot plot?

Back

A dot plot is a simple way to display data using dots above a number line, where each dot represents one data point.

Front

How do you read a dot plot?

Back

To read a dot plot, count the number of dots above each value on the number line to see how many times that value occurs.

Front

What does each dot represent in a dot plot?

Back

Each dot represents one occurrence of a data point.

Front

How can you find the total number of items represented in a dot plot?

Back

Add up all the dots above the values to find the total number of items.

Front

What is the purpose of using a dot plot?

Back

A dot plot helps to visualize data and make it easier to see patterns, trends, and frequencies.

Front

What is the mode in a set of data?

Back

The mode is the number that appears most frequently in a data set.

Front

How do you find the mode using a dot plot?

Front

What is the range of a set of numbers?

Back

The range is the difference between the highest and lowest values in a data set.

Front

How do you calculate the range from a dot plot?

Back

Identify the highest and lowest values represented in the dot plot and subtract the lowest from the highest.

Front

What does it mean if a dot plot is symmetrical?

Back

A symmetrical dot plot has a balanced distribution of data points on either side of the center.
