Dot Plots

Front

What is a dot plot?

Back

A dot plot is a statistical chart that consists of dots plotted above a number line, representing the frequency of data points.

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 mode represent in a data set?

Back

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

Front

How do you determine the median of a data set?

Back

To find the median, arrange the data in numerical order and identify the middle value. If there is an even number of values, average the two middle values.

Front

What is the purpose of a dot plot?

Back

Dot plots are used to visualize the distribution of data points and to identify patterns, trends, and outliers.

Front

How can you identify the mode from a dot plot?

Back

The mode can be identified by locating the value with the highest number of dots above it on the dot plot.

Front

What is the difference between mean and median?

Back

The mean is the average of all values, while the median is the middle value when the data is ordered.

Front

How do you interpret the frequency of scores in a dot plot?

Back

The frequency of scores is indicated by the number of dots above each score on the plot, showing how many times each score occurred.

Front

What does it mean if a dot plot has multiple modes?

Back

If a dot plot has multiple modes, it is called multimodal, indicating that there are several values that appear with the highest frequency.

Front

How can you use a dot plot to compare two data sets?

Back

You can overlay two dot plots on the same number line to visually compare the frequency and distribution of scores between the two data sets.
