This tool provides individuals with opportunities to quiz themselves on levels of measurement in a game-like environment much like "Who Wants to be a Millionaire."

This interactive lecture activity motivates the need for sampling. "Why sample, why not just take a census?" Under time pressure, students count the number of times the letter F appears in a...

This activity explores the dynamics of a sound wave produced by a string instrument using simulation. A simplified physical model highlights important scientific and mathematical features. The sound...

In this module, students can test their knowledge of levels of measurement by attempting to determine the the level of measurement of ten different variables. For each variable, a statement is also...

This chapter of the NIST Engineering Statistics handbook describes the measurement process characterization with discussions of control, calibration, gauge studies, and uncertainty analysis, and a...

This article illustrates the difficulty in defining an event you are dealing with and that, even if you can define the event properly, you may encounter rough bounds on the probability of that event...
