The video tutorial provides a step-by-step guide on marking data on line plots using a Khan Academy exercise. It begins with measuring distances from a house to various locations and plotting these on a line plot. The tutorial then shifts to measuring line lengths to the nearest quarter inch and plotting these measurements. The video emphasizes understanding data visualization through line plots and concludes with a review of the exercise.
