The values that divide each part are called the first second and third quartiles. Next press Stat and then scroll over to the right and press CALC. These values are quartile 1 Q1 and quartile 3 Q3. The values that divide each part are called the first second and third quartiles. If playback doesnt begin shortly try restarting. Then we try to find the interquartile ran.
