The video tutorial explains the concepts of accuracy, precision, and reliability using a game of darts and a chemistry experiment. Accuracy is how close a measurement is to the true value, precision is how close measurements are to each other, and reliability is the ability to repeat measurements with similar results. The tutorial uses examples of dart throws and gas volume measurements to illustrate these concepts, emphasizing the importance of averaging for accuracy and consistency for precision and reliability.
