Analyze Line Plots & Dot Plots

Front

What is a line plot?

Back

A line plot is a graph that shows the frequency of data along a number line, using X's or dots to represent each data point.

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 find the range of a data set?

Back

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

Front

What does the mean represent in a data set?

Back

The mean is the average of a set of numbers, calculated by adding all the values together and dividing by the number of values.

Front

How can you determine the mode of a data set?

Back

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

Front

What is the median of a data set?

Back

The median is the middle value when the data set is ordered from least to greatest.

Front

How do you interpret a dot plot?

Back

To interpret a dot plot, count the number of dots above each value to understand the frequency of each data point.

Front

What is the purpose of using line plots and dot plots?

Back

Line plots and dot plots help visualize data, making it easier to see patterns, trends, and frequencies.

Front

How do you calculate the total number of data points from a dot plot?

Back

Count the total number of dots in the dot plot to find the total number of data points.

Front

What does it mean if a line plot has a peak?

Back

A peak in a line plot indicates the value with the highest frequency, showing where most data points are concentrated.
