Exploring Box and Whisker Plots

What does a box-and-whisker plot visually represent?

• Probability distributions

• Median, quartiles, and interquartile range

• Mean, mode, and standard deviation

• Cumulative frequency

How many parts does a box-and-whisker plot divide the data into?

• Six

• Two

• Four

• Eight

What do the whiskers in a box-and-whisker plot represent?

• First and third quartiles

• Mean and median

• Maximum and minimum values

• Standard deviation

What is the interquartile range (IQR)?

• Difference between Q3 and Q1

• Average of all data points

• Difference between the highest and lowest values

• Sum of all quartiles

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

• As the center of the box

• As a line within the box

• As the longest whisker

• As the highest point

When constructing a box-and-whisker plot, what is the first step?

• Ordering the data from least to greatest

• Identifying the median

• Drawing the whiskers

• Calculating the range

What does the box in a box-and-whisker plot represent?

• The interquartile range

• The mean of the data

• The range of the data

• The total data set

How do you find the range in a box-and-whisker plot?

• Q3 minus median

• Q3 minus Q1

• Highest value minus lowest value

• Median minus Q1

In a box-and-whisker plot, if the highest value is also Q3, what does it indicate?

• There are no outliers

• The median is incorrectly calculated

• The data is uniformly distributed

• There is an error in the plot

What is the correct way to calculate IQR?

• Subtract Q3 from Q1

• Subtract the median from Q3

• Subtract Q1 from Q3

• Add Q1 and Q3
