Statistics Basics

What is an outlier in a dataset?

• A value that is close to the mean

• A value that is significantly different from other values

• A value that is the same as the median

• A value that is the same as the mode

In a box plot, what does the box represent?

• The range of the data

• The interquartile range (IQR)

• The mean of the data

• The mode of the data
