What is the difference between a box plot, a line plot, and a histogram?
Box Plot- data is displayed by using the 5 number summary (minimum, lower quartile, median, upper quartile, and maximum).
Line plot- data is displayed by a dot or mark above a number line.
Histogram- data is displayed by bars in the graph.
