Box Plot

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 IQR stand for?

Back

IQR stands for Interquartile Range, which measures the spread of the middle 50% of a dataset.

Front

How do you calculate the IQR?

Back

To calculate the IQR, subtract the first quartile (Q1) from the third quartile (Q3): IQR = Q3 - Q1.

Front

What does a larger IQR indicate?

Back

A larger IQR indicates a greater spread in the middle 50% of the data, suggesting more variability.

Front

What does a smaller IQR indicate?

Back

A smaller IQR indicates that the middle 50% of the data points are closer together, suggesting less variability.

Front

What is the median in a Box Plot?

Back

The median is the middle value of a dataset when it is ordered from least to greatest, represented by the line inside the box of a Box Plot.

Front

What are quartiles?

Back

Quartiles are values that divide a dataset into four equal parts, with Q1 being the first quartile, Q2 the median, and Q3 the third quartile.

Front

What is the five-number summary?

Back

The five-number summary includes the minimum, Q1, median (Q2), Q3, and maximum values of a dataset.

Front

How can you identify outliers in a Box Plot?

Back

Outliers can be identified in a Box Plot as points that fall outside the range of Q1 - 1.5*IQR and Q3 + 1.5*IQR.

Front

What does the length of the box in a Box Plot represent?

Back

The length of the box represents the IQR, showing the range of the middle 50% of the data.
