Answer:
J. The mode cannot be determined.
Explanation:
Mode cannot be directly examined with a box & whisker plot such as this. The nature of this sort of representation just doesn't make it possible.
To find mode, the ideal way is to set the data of numbers from least to greatest (in order), then examine which numbers shows up the most.
Fun fact: Another great way to represent the mode is by using a DOT Plot; this is where you plot each number based on how many times it shows up on a graph. The number with the most marks is the mode because that number is what shows up most in the data.
Provided in the attachment is an example of a box plot; of which the mode is 100 as it has the most marks.
