What is a box plot?

Back

A box plot, also known as a whisker plot, is a standardized way of displaying the distribution of data based on a five-number summary: minimum, first quartile (Q1), median, third quartile (Q3), and maximum.

Front

What does the minimum value represent in a box plot?

Back

The minimum value in a box plot represents the smallest data point in the dataset.

Front

What does the maximum value represent in a box plot?

Back

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

Front

What are quartiles in statistics?

Back

Quartiles are values that divide a dataset into four equal parts, with each part representing 25% of the data.

Front

How do you find the median of a dataset?

Back

To find the median, arrange the data in ascending order and locate the middle value. If there is an even number of observations, the median is the average of the two middle values.

Front

What is the first quartile (Q1)?

Back

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

Front

What is the third quartile (Q3)?

Back

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

Front

What does the interquartile range (IQR) measure?

Back

The interquartile range (IQR) measures the spread of the middle 50% of the data and is calculated as Q3 - Q1.

Front

How do you identify outliers in a box plot?

Back

Outliers can be identified in a box plot as points that fall below Q1 - 1.5 * IQR or above Q3 + 1.5 * IQR.

Front

What is the purpose of a box plot?

Back

The purpose of a box plot is to provide a visual summary of the central tendency, variability, and distribution of a dataset.
