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.
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.
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.
Grouped Numerical Frequency Distributions: An Overview -- First in a Series
In this interactive object, students read about organizing data in a tabular form. A brief quiz completes the activity. This is the first in a series of six learning objects.
The Operation of a Multiplexer/Demultiplexer Circuit
In this animated object, learners examine how a multiplexer and a demultiplexer work together when their data select lines are connected to the same binary counter.
