A Box and Whisker 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 the lower quartile (Q1) represent in a Box and Whisker Plot?

Back

The lower quartile (Q1) represents the value below which 25% of the data falls.

Front

How do you find the median in a dataset?

Back

To find the median, arrange the data in ascending order and locate the middle number. If there are two middle numbers, add them together and divide by 2.

Front

What is the Interquartile Range (IQR)?

Back

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

Front

What does the whisker in a Box and Whisker Plot represent?

Back

The whiskers in a Box and Whisker Plot extend from the quartiles to the minimum and maximum values, showing the spread of the data.

Front

If a Box and Whisker Plot shows Q1 as 60 and Q3 as 75, what is the IQR?

Back

The IQR is 75 - 60 = 15.

Front

What percentage of data lies between Q1 and Q3 in a Box and Whisker Plot?

Back

50% of the data lies between Q1 and Q3.

Front

How do you determine the maximum value in a Box and Whisker Plot?

Back

The maximum value is the highest data point in the dataset.

Front

What is the significance of the median in a Box and Whisker Plot?

Back

The median divides the dataset into two equal halves, with 50% of the data below and 50% above it.

Front

What do you do if the dataset has an even number of values when finding the median?

Back
