Comparing Box and Whisker Plots

What is the first step in comparing box and whisker plots?

• Identify the median

• Read the problem and graph

• Calculate the IQR

• Label the data points

What cannot be determined directly from a box and whisker plot?

• Range

• IQR

• Mean

• Median

What does the box in a box plot represent?

• Maximum and minimum values

• First and third quartiles

• Middle 50% of the data

• Mean and median

How is the spread of data in a box plot determined?

• Maximum minus minimum

• Median minus mean

• IQR

• Q1 minus Q3

What does the median represent in a box plot?

• The difference between the highest and lowest values

• The most frequent value in the dataset

• The middle value of the dataset

• The average value of the dataset

What is the significance of the range in a box plot analysis?

• It calculates the average value of the data

• It represents the median of the dataset

• It indicates the total spread of the data

• It shows the middle 50% of the data

In a box plot, what does skewness indicate?

• The mean is greater than the median

• There is an equal number of data points on each side of the median

• The median is not centered

• Data is evenly distributed

What is the correct inference if the IQR for one class is twice that of another?

• The first class has a wider spread of ages

• Both classes have students of the same age

• The classes have the same median age

• The second class has a larger range of ages

Which statement is true when comparing the youngest student enrolled in two classes?

• Both classes have students of the same youngest age

• One class has younger students than the other

• The youngest student's age is the median

• The youngest age can't be determined from a box plot

How can you identify a false statement based on a double box plot?

• By comparing the medians of both plots

• By identifying the statement that contradicts the plot's data

• By calculating the mean of the datasets

• By finding the statement that applies to both plots
