Interpreting Box Plots

Front

What is a box plot?

Back

A box plot is a graphical representation of a dataset that shows its minimum, first quartile (Q1), median, third quartile (Q3), and maximum values.

Front

What does the maximum value in a box plot represent?

Back

The maximum value in a box plot represents the highest data point in the dataset.

Front

What is the lower quartile (Q1) in a box plot?

Back

The lower quartile (Q1) is the median of the lower half of the dataset, representing the 25th percentile.

Front

What does the median represent in a box plot?

Back

The median is the middle value of the dataset when it is ordered, dividing the dataset into two equal halves.

Front

What is the upper quartile (Q3) in a box plot?

Back

The upper quartile (Q3) is the median of the upper half of the dataset, representing the 75th percentile.

Front

How do you calculate the interquartile range (IQR)?

Back

The interquartile range (IQR) is calculated by subtracting Q1 from Q3 (IQR = Q3 - Q1).

Front

What does the whisker in a box plot represent?

Back

The whiskers in a box plot extend from the quartiles to the minimum and maximum values, showing the range of the data.

Front

What percentage of data falls between Q1 and Q3 in a box plot?

Back

50% of the data falls between Q1 and Q3 in a box plot.

Front

What does a box plot tell you about the distribution of data?

Back

A box plot provides insights into the central tendency, variability, and skewness of the data distribution.

Front

How can you identify outliers in a box plot?

Back

Outliers in a box plot are typically represented as individual points that fall outside the whiskers.
