Exploring Box and Whisker Plots

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

• To represent data in time series

• To summarize data distribution

• To display every individual data point

• To calculate data averages

Which of the following is NOT one of the five key numbers in a box plot?

• Minimum

• Upper Quartile

• Mean

• Median

What does the upper quartile represent in a box plot?

• The maximum data value

• The median of the upper half of the data

• The median of the lower half of the data

• The average value of the dataset

How is the inner quartile range calculated?

• Average of upper and lower quartiles

• Maximum minus minimum

• Median of all data points

• Upper quartile minus lower quartile

Which line in a box plot typically represents the median?

• The first vertical line

• The second vertical line

• The middle line of the box

• The last vertical line

In constructing a box plot, what is the first step?

• Drawing the whiskers

• Calculating the median

• Identifying outliers

• Ordering the data from least to greatest

How do you find the lower quartile in a dataset?

• It's the smallest data value

• It's the average of all data points

• It's the value just below the dataset's median

• It's the median of the lower half of the data

What does the inner quartile range tell us about a dataset?

• The difference between the highest and lowest values

• The average value of the data

• The total spread of the data

• The range of the most central 50% of the data

What is indicated by a shorter box in a box plot?

• Less variability in the middle 50% of the data

• More outliers in the data

• Higher overall data values

• Lower minimum data value

What does a longer whisker on one end of the box plot indicate?

• The median is closer to the maximum or minimum

• Data is uniformly distributed

• Greater spread of data on that side

• More data points near the median
