Comparing Box and Whisker Plots

What is the primary reason for using increments of 25% in box and whisker plots?

• To make the plots look more balanced

• Because each section represents 25% of the data

• To simplify the calculation process

• To align with statistical standards

Why do we avoid using the extremes when comparing box and whisker plots?

• They do not provide useful information

• They only represent one person

• They represent outliers

• They are difficult to calculate

Which period had a higher median score?

• The video does not specify

• Both were equal

• Period 4

• Period 3

What percentage of Period 4 scored above 75?

• 25%

• 100%

• 50%

• 75%

Why is comparing medians useful in box and whisker plots?

• It calculates the average score

• It represents the middle point of data

• It indicates the highest score

• It shows the range of scores

How does the upper quartile of Period 3 compare to Period 4?

• Period 4 is higher

• Both are the same

• Period 3 is higher

• The video does not specify

What does the upper quartile represent in a box and whisker plot?

• The average score

• The highest 25% of scores

• The median score

• The lowest 25% of scores

Which period's upper quartile matches the median of the other period?

• None of the above

• Period 3's upper quartile matches Period 4's median

• Period 4's upper quartile matches Period 3's median

• Both periods' upper quartiles match each other's medians

What argument could be made for Period 3 performing better?

• Lower quartile scores were higher

• Higher median score

• Higher upper quartile score

• More consistent scores

What does the lower quartile indicate in a box and whisker plot?

• The average score

• The lowest 25% of scores

• The highest 25% of scores

• The median score
