Modified Box Plot Quiz

What is the primary difference between a standard box plot and a modified box plot?

• A modified box plot uses a different scale.

• A modified box plot identifies and marks outliers.

• A modified box plot includes a histogram.

• A modified box plot does not show quartiles.

Which of the following is NOT one of the five key data points needed for a box plot?

• Maximum

• Mode

• Median

• Minimum

How is the median determined in a data set with an even number of values?

• By averaging the two middle values

• By selecting the lowest value

• By selecting the middle value

• By selecting the highest value

What is the Interquartile Range (IQR) used for in a box plot?

• To find the mean of the data set

• To determine the range of the data set

• To identify the spread of the middle 50% of the data

• To calculate the standard deviation

How do you calculate the IQR?

• Subtract the first quartile from the third quartile

• Add the first and third quartiles

• Subtract the minimum from the maximum

• Divide the sum of all data points by the number of points

What is the purpose of multiplying the IQR by 1.5?

• To find the mean

• To adjust the quartiles

• To determine the outlier threshold

• To calculate the median

What is considered an outlier in a modified box plot?

• Any value equal to the median

• Any value equal to the maximum

• Any value within the IQR

• Any value outside the upper and lower limits

If a data point is identified as an outlier, what happens to the minimum value in a modified box plot?

• It is replaced by the next lowest non-outlier value

• It remains the same

• It is replaced by the maximum value

• It is replaced by the median

How is an outlier represented in a modified box plot?

• With a circle

• With a triangle

• With a square

• With an asterisk

Why is it called a 'modified' box plot?

• Because it adjusts for outliers

• Because it excludes the median

• Because it uses a different color scheme

• Because it includes a histogram
