What is the Five Number Summary?

Back

The Five Number Summary consists of five key statistics that summarize a dataset: Minimum, First Quartile (Q1), Median (Q2), Third Quartile (Q3), and Maximum.

Front

What does the Minimum represent in a dataset?

Back

The Minimum is the smallest value in a dataset.

Front

What is the Median in a dataset?

Back

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

Front

What are Quartiles?

Back

Quartiles are values that divide a dataset into four equal parts. Q1 is the first quartile (25th percentile), Q2 is the median (50th percentile), and Q3 is the third quartile (75th percentile).

Front

How do you find the First Quartile (Q1)?

Back

To find Q1, arrange the data in ascending order and find the median of the lower half of the dataset.

Front

How do you find the Third 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 Upper Quartile (Q3) for the dataset: 136, 150, 119, 150, 125, 143?

Back

Q3 is 150.

Front

What is the Minimum value for the dataset: 2, 3, 6, 6, 8, 10, 12?

Back

The Minimum value is 2.

Front

What is the Median for the dataset: 23, 34, 27, 7, 30, 26, 28, 31, 34?

Back

The Median is 28.

Front

What is the definition of Range in statistics?

Back

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