Box Plots

Front

What is a box plot?

Back

A box plot is a graphical representation of a dataset that displays its minimum, first quartile, median, third quartile, and maximum.

Front

What does the median represent in a dataset?

Back

The median is the middle value of a dataset when it is ordered from least to greatest.

Front

How do you find the first quartile (Q1) in a dataset?

Back

The first quartile (Q1) is the median of the lower half of the dataset.

Front

What is the maximum value in a box plot?

Back

The maximum value is the highest data point in the dataset represented in the box plot.

Front

What percentage of data lies between the first and third quartiles?

Back

50% of the data lies between the first quartile (Q1) and the third quartile (Q3).

Front

How do you calculate the median of a dataset with an even number of values?

Back

To find the median of an even number of values, average the two middle numbers.

Front

What is the interquartile range (IQR)?

Back

The interquartile range (IQR) is the difference between the third quartile (Q3) and the first quartile (Q1), representing the middle 50% of the data.

Front

What does a box plot indicate about the spread of data?

Back

A box plot shows the spread of data by displaying the range, quartiles, and any potential outliers.

Front

What is an outlier in a dataset?

Back

An outlier is a data point that is significantly different from the other data points in the dataset.

Front

How can you identify outliers using a box plot?

Back

Outliers can be identified in a box plot as points that fall outside the whiskers, which typically extend 1.5 times the IQR from the quartiles.
