Dot Plots and Box Plots

Front

What is a dot plot?

Back

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

Front

What is a box plot?

Back

A box plot, or box-and-whisker plot, is a graphical representation of data that shows the distribution through five summary statistics: minimum, first quartile, median, third quartile, and maximum.

How do you find the range of a data set?

Back

The range is found by subtracting the lowest value from the highest value in the data set.

Front

What does the mean represent in a data set?

Back

The mean is the average of a data set, calculated by adding all the numbers together and dividing by the total count of numbers.

Front

What is the median in a data set?

Back

The median is the middle value when the data points are arranged in order. If there is an even number of data points, the median is the average of the two middle numbers.

Front

What is the mode of a data set?

Back

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

Front

How do you interpret a dot plot?

Back

A dot plot is interpreted by counting the number of dots above each value, which indicates the frequency of that value in the data set.

Front

What information does a box plot provide?

Back

A box plot provides information about the central tendency, variability, and distribution of a data set, including outliers.

Front

What is an outlier in a data set?

Back

An outlier is a data point that is significantly different from the other data points in the set, often lying outside the range of the other values.

Front

How can you identify the highest score in a box plot?

Back

The highest score in a box plot is represented by the maximum value, which is the rightmost point of the whisker.
