Learners view a horizontal curve and mouse over the diagram to read descriptions of its components and related equations.

Learners follow the steps required to perform the Ziegler-Nichols reaction curve process identification procedure.

Learners study the mathematical calculations used to determine the proper PID values to be entered into a controller using the Ziegler-Nichols Reaction Curve.

Learners perform the steps required for the Ziegler-Nichols Reaction Curve Tuning Method. The process identification procedure is performed, calculations are made, and the proper PID values are programmed into the controller.

Students examine the drain curves for a JFET. They are also introduced to vocabulary terms and formulas.

In this learning activity you'll explore normal distribution and enter values for the mean and the standard deviation of normally distributed data and observe the resulting changes in the shape of the normal curve.

In this learning activity you'll identify and calculate the area under the normal curve specified by given z-scores.

Students read about the concepts of saturation and cutoff. They view diagrams that illustrate the interaction of the load line and the family of curves.

Learners read a brief introduction to in-control and out-of-control conditions and view a series of distribution curves. This is a follow-up to the learning object titled "Quality Basics: Variation."

In this learning object you'll examine the supply and demand curves and to demonstrate the effects on equilibrium price/quantity and on price ceilings and floors.
