What is a box and whisker plot?

Back

A box and whisker plot is a graphical representation of data that shows the distribution through five summary statistics: minimum, first quartile (Q1), median, third quartile (Q3), and maximum.

Front

What does the lower quartile (Q1) represent in a box and whisker plot?

Back

The lower quartile (Q1) represents the median of the lower half of the data set, indicating that 25% of the data points fall below this value.

Front

How do 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 in a data set?

Back

The median is the middle value when the data set is ordered from least to greatest. If there is an even number of observations, the median is the average of the two middle numbers.

Front

What does it mean if a dot plot is skewed to the right?

Back

If a dot plot is skewed to the right, it means that the tail on the right side of the distribution is longer or fatter than the left side, indicating that there are a few higher values.

Front

How do you find the median of two data sets?

Back

To find the median of two data sets, combine the data points from both sets, order them from least to greatest, and then find the middle value.

Front

What is the significance of the maximum value in a box and whisker plot?

Back

The maximum value in a box and whisker plot represents the highest data point in the data set.

Front

What is a dot plot?

Back

A dot plot is a simple statistical chart that consists of dots plotted above a number line, where each dot represents a data point.

Front

How can you identify the range of a data set?

Back

The range of a data set is calculated by subtracting the minimum value from the maximum value.

Front

What does it mean for a data set to be bimodal?

Back

A bimodal data set has two modes, meaning there are two values that appear most frequently.
