Box Plot & MAD

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.

What does MAD stand for?

Back

MAD stands for Mean Absolute Deviation, which measures the average distance between each data point and the mean of the dataset.

Front

How do you calculate the Mean Absolute Deviation (MAD)?

Back

1. Find the mean of the data. 2. Subtract the mean from each data point and take the absolute value. 3. Find the average of these absolute values.

Front

What is the formula for calculating the range of a dataset?

Back

Range = Maximum value - Minimum value.

Front

What is the Interquartile Range (IQR)?

Back

The Interquartile Range (IQR) is the difference between the third quartile (Q3) and the first quartile (Q1), representing the middle 50% of the data.

Front

How do you find the upper quartile (Q3)?

Back

To find Q3, arrange the data in ascending order and find the median of the upper half of the dataset.

Front

What is the median of a dataset?

Back

The median is the middle value when the data is arranged in ascending order. If there is an even number of values, it is the average of the two middle values.

Front

What does it mean if a dataset has a high MAD?

Back

A high MAD indicates that the data points are spread out widely from the mean, showing high variability.

Front

What does it mean if a dataset has a low MAD?

Back

A low MAD indicates that the data points are close to the mean, showing low variability.

Front

How do you interpret a Box Plot?

Back

A Box Plot shows the distribution of data, highlighting the median, quartiles, and potential outliers.
