Modified Box Plot Quiz

What is a modified box plot?

• A plot that only shows the median

• A box and whisker plot that includes outliers

• A plot that excludes the maximum value

• A plot that only shows quartiles

Which of the following is NOT needed to create a modified box plot?

• Maximum value

• Quartiles

• Mean value

• Minimum value

Why is it important to order data from least to greatest when creating a box plot?

• To simplify the plot

• To make calculations easier

• To ensure accurate quartile determination

• To highlight the largest number

How is the median (quartile 2) determined in a data set?

• By subtracting the minimum from the maximum

• By counting to the middle of the data set

• By finding the average of all numbers

• By adding the first and last numbers

What is the interquartile range (IQR)?

• The average of quartile 1 and quartile 3

• The difference between quartile 3 and quartile 1

• The sum of all quartiles

• The difference between the maximum and minimum

How do you calculate the upper limit for outliers?

• Subtract the IQR from quartile 3

• Add the IQR to quartile 1

• Multiply quartile 3 by 1.5

• Add 1.5 times the IQR to quartile 3

What happens to the maximum value in a modified box plot if an outlier is identified?

• It is doubled

• It is ignored

• It remains the same

• It is replaced by the next highest value

What is the purpose of marking outliers in a modified box plot?

• To prevent skewing the data representation

• To highlight the median

• To ensure all data points are included

• To make the plot look more complex

Which symbol is typically used to mark an outlier in a modified box plot?

• A circle

• An asterisk

• A triangle

• A square

What is the new maximum value in the modified box plot if 94 is an outlier?

• 31

• 45

• 94

• 61
