What is a box plot?

Back

A box plot is a graphical representation of a dataset that displays the median, quartiles, and potential outliers.

Front

What does the median represent in a dataset?

Back

The median is the middle value that separates the higher half from the lower half of a dataset.

Front

How do you find the interquartile range (IQR)?

Back

IQR is calculated as the difference between the third quartile (Q3) and the first quartile (Q1): IQR = Q3 - Q1.

Front

What does the first quartile (Q1) represent?

Back

Q1 is the median of the lower half of the dataset, representing the 25th percentile.

Front

What does the third quartile (Q3) represent?

Back

Q3 is the median of the upper half of the dataset, representing the 75th percentile.

Front

What is the purpose of a box plot?

Back

Box plots are used to visualize the distribution of data, identify outliers, and compare different datasets.

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 can you identify outliers in a box plot?

Back

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

Front

What is the range of a dataset?

Back

The range is the difference between the maximum and minimum values in a dataset.

Front

If the median of a dataset is 62, what does this indicate?

Back

This indicates that half of the data values are below 62 and half are above 62.
