In this learning activity you'll recognize several patterns on an Xbar and R control chart. These non-random patterns are indications that the process is not in a state of statistical control.

In this animated object, learners view molecules as they collide and move between two different solutions. They also observe what happens when the temperature of the solutions is raised or lowered.

Learners click on the root word of a medical term in the left-hand column and drag it to its definition in the right-hand column. There is a time limit, so students will need to train themselves to recognize these root words quickly. Students may repeat the activity as often as they wish. A total of 74 terms are given in random order.

In this interactive exercise, learners review definitions of 26 terms and then test their knowledge in a matching exercise. Only six terms are included in the quiz; however, if the learner clicks “Restart,” more terms appear in random order.
