To determine which class shows the smallest spread in scores based on box plots, you would typically look at the interquartile range (IQR) or the overall range (distance between the minimum and maximum values). The smaller the distance between the quartiles and the overall range, the smaller the spread of scores.
Since I do not have access to the visual box plots you mentioned, I can’t analyze them directly. However, I can guide you on how to assess them:
-
Look at the length of the boxes: In a box plot, the length of the box represents the IQR (the range between the first and third quartiles). A shorter box indicates a smaller spread.
-
Examine the whiskers: The whiskers extend to the minimum and maximum values, so look at how far these extend. If the whiskers are short, it indicates that the overall spread is also small.
Based on these criteria, identify which class has the shortest box and whiskers. That class will have the smallest spread in scores.
If you provide more information or describe the box plots, I can help you further analyze them.
