In the line plot shown, the weights of the apple bags are shown along the number line and the number of cross marks above each weight indicates the number of apple bags sold.

The number that occurs most frequently in a data set is the mode of the data set.

11 lb is the mode.
[Because, most number of cross marks appear above 11 lb apple bags.]
