Exploring Box Plots

The video tutorial by Mrs. Gaul introduces sixth graders to box plots, also known as box and whisker plots. It explains how box plots display data distribution and divide data into quartiles. The tutorial covers key concepts such as the median, lower quartile, upper quartile, and interquartile range. Through examples, students learn how to find these quartiles and create a box plot. The video also demonstrates how to analyze box plots to answer questions about data, emphasizing the importance of understanding each section's representation of 25% of the data.

What does a box plot primarily show about a dataset?

• The exact values of all data points

• Only the highest and lowest values

• The distribution and spread of data

• The mean and mode of the data

What is the median in a dataset?

• The middle value when data is ordered

• The difference between the highest and lowest values

• The average of all data points

• The most frequently occurring value

How is the lower quartile (LQ) determined in a dataset?

• By subtracting the median from the maximum value

• By finding the median of the upper half of the data

• By averaging the highest and lowest values

• By finding the median of the lower half of the data

What does the interquartile range represent?

• Range between the median and the maximum value

• Range between the first and third quartiles

• Total spread of the dataset

• Difference between the maximum and minimum values

In creating a box plot, what does the box represent?

• Only the median value

• The total dataset

• Data between the lower and upper quartiles

• Range from minimum to maximum

What is indicated by the whiskers in a box plot?

• The quartiles of the dataset

• The minimum and maximum values

• The median and mode

• The mean of the data

How can you find the median number from a box plot?

• It is indicated by the whiskers

• It is the start of the box

• It is the end of the box

• It is the line inside the box

What does the upper quartile in a box plot indicate?

• The median of the upper half of the data

• The median of the lower half of the data

• The median of the entire dataset

• The maximum value of the dataset

What is the interquartile range calculated from a box plot?

• Median minus minimum

• Maximum minus minimum

• Upper quartile minus median

• Upper quartile minus lower quartile

What percentage of the data is represented by each section of the box plot?

• 10%

• 100%

• 25%

• 50%
