• 
• 
• 
•

Consider the following box plot:

What percentage of the data sits between 27 and 33?

• 25%

• 50%

• 68%

• 75%

Consider the following box plot:

What percentage of the data sits below 33?

• 25%

• 50%

• 68%

• 75%

Consider the following box plot:

If 20,000 people were surveyed. How many would you expect would score more 27 points?

Answer explanation

75% would sit above the LQ, therefore 75% of 20,000 people is 15,000.

Match the following statements which link to the normally distributed graph pictured:

• two standard deviations above the mean

• 34% of the data sits

• one standard deviation of the mean

• 68% of the data sits within

• two standard deviations of the mean

• 95% of the data sits within

• one standard deviation below the mean

• 99.7% of the data sits within

• three standard deviations of the mean

• 47.5% of the data sits
