Box Plots

Front

What is a box plot?

Back

A box plot, also known as a whisker plot, is a graphical representation of a dataset that displays its minimum, first quartile (Q1), median, third quartile (Q3), 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. It divides the dataset into two equal halves.

Front

How do you find the upper quartile (Q3)?

Back

The upper quartile (Q3) is the median of the upper half of the dataset, which includes all values above the median.

Front

What is the lower quartile (Q1)?

Back

The lower quartile (Q1) is the median of the lower half of the dataset, which includes all values below the median.

Front

What is the interquartile range (IQR)?

Back

The interquartile range (IQR) is the difference between the upper quartile (Q3) and the lower quartile (Q1). It measures the spread of the middle 50% of the data.

Front

How do you calculate the interquartile range?

Back

IQR = Q3 - Q1.

Front

What does a box plot visually represent?

Back

A box plot visually represents the distribution of a dataset, highlighting its central tendency, variability, and potential outliers.

Front

What is the significance of the whiskers in a box plot?

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 does it mean if a box plot is skewed?

Back

If a box plot is skewed, it indicates that the data is not symmetrically distributed, with a longer tail on one side.

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.
