Understanding Box Plots

What is the primary purpose of using a box plot?

• To display individual data points

• To compare two unrelated datasets

• To calculate the average of a dataset

• To summarize large amounts of data

Which value is used to split a dataset into two equal groups?

• The median

• The range

• The mode

• The mean

What are the five key values needed to construct a box plot?

• First quartile, second quartile, third quartile, fourth quartile, fifth quartile

• Minimum, maximum, average, sum, count

• Lower extreme, lower quartile, median, upper quartile, upper extreme

• Mean, mode, range, variance, standard deviation

How do you handle a dataset with no single middle value when finding the median?

• Use the smallest value

• Use the largest value

• Use the average of the two middle values

• Use the first value

What does a shorter distance in a box plot's quartile indicate?

• The data is skewed

• The data has more outliers

• The data is bunched together

• The data is more spread out
