Learners read about the different uses of the word "data." They will test themselves on examples of data that is singular, plural, qualitative, quantitative, nominal, ordinal, interval, rational, discrete, or continuous.
In this interactive object, learners read how to arrange numerical data manually by using ascending or descending order. They also practice arranging the data using a spreadsheet.
In this animated object, learners examine three data compare instructions used by programmable logic controllers (PLCs). A practical application to show how these instructions are used in an industrial setting is provided.
Basic Types of Dimensioning Used in Engineering Drawings
Learners examine the basic types of dimensioning including unidirectional and aligned systems, and linear, aligned, angled, arrowless, chain, datum, chart, tabular, radius, diameter, typical, and reference dimensions.
The Multiplexer/Demultiplexer IC Data Transfer Circuit
In this animated activity, the learner examines how a 74150 IC multiplexer and a 74154 IC demultiplexer work together when their data select lines are connected to the same input devices.
Common Types of Oxidation-Reduction Reactions (Screencast)
Learners identify combination, decomposition, displacement, and combustion types of redox reactions. They also watch a video clip that demonstrates the reaction of sodium and water.
