Comparing Data: Box and Dot Plots

Front

What is a box plot?

Back

A box 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 a dot plot represent?

Back

A dot plot is a simple visual display of data where each data point is represented by a dot above a number line, allowing for easy comparison of frequencies.

Front

What does it mean if data is skewed left?

Back

If data is skewed left, it means that the left tail of the distribution is longer or fatter than the right tail, indicating that most values are concentrated on the right.

Front

What does it mean if data is skewed right?

Back

If data is skewed right, it means that the right tail of the distribution is longer or fatter than the left tail, indicating that most values are concentrated on the left.

Front

What is the median in a data set?

Back

The median is the middle value of a data set when it 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 is the range of a data set?

Back

The range is the difference between the highest and lowest values in a data set, indicating the spread of the data.

Front

What is a measure of center?

Back

A measure of center is a value that represents the center or typical value of a data set, commonly calculated as the mean, median, or mode.

Front

What is a measure of variation?

Back

A measure of variation describes how spread out the values in a data set are, commonly assessed using range, variance, or standard deviation.

Front

How do you interpret a box plot?

Back

A box plot shows the median, quartiles, and potential outliers of a data set, allowing for quick visual comparison of distributions between different groups.

Front

What does it mean if two data sets have the same range?

Back

If two data sets have the same range, it means that the difference between their maximum and minimum values is the same, but it does not indicate that the data sets are identical.
