Analyzing Bank Fees with Box and Whisker Plots

What is the primary purpose of a box and whisker plot?

• To calculate the average of a data set

• To visually summarize data into quartiles

• To find the exact value of each data point

• To determine the mode of the data set

What triggers an overdraft fee?

• Transferring money between accounts

• Depositing a check

• Withdrawing more money than the account balance

• Earning interest on the account balance

What is the first step in creating a box and whisker plot?

• Ordering the data from least to greatest

• Drawing the whiskers

• Identifying outliers

• Calculating the median

Why is it important to monitor your checking account balance?

• To avoid overdraft fees

• To deposit checks

• To earn interest

• To transfer money

How is the median value represented in a box and whisker plot?

• As the leftmost point of the box

• As a dotted line within the box

• As the rightmost point of the box

• As the highest point of the whisker

What value is used to calculate the first quartile in a box and whisker plot?

• The maximum value of the data set

• The median of the entire data set

• The average of the two middlemost numbers to the left of the median

• The minimum value of the data set

How is the maximum value represented in a box and whisker plot?

• As the end point of the right whisker

• As the start point of the left whisker

• As the bottom of the box

• As the top of the box

What does the interquartile range (IQR) represent?

• The total number of data points

• The average value of the data set

• The range between the minimum and maximum values

• The range between the first and third quartiles

What can the IQR help researchers identify?

• The average value of the data

• The total range of the data set

• Data points that may be outliers

• The median of the data set

What is the correct order of steps to analyze data with a box and whisker plot?

• Draw plot, identify outliers, calculate median

• Calculate IQR, draw whiskers, identify median

• Order data, identify quartiles, draw plot

• Identify median, draw box, calculate IQR
