Levels of measurement
Aimed at statistics beginners, this learning object describes, and gives examples of, the four levels of measurement of data: nominal, ordinal, interval and ratio.
Antenna Design and Measurement Techniques
The aim of this short course is to familiarize students with antennas, in a quite practical way. Students will acquire knowledge about all the main aspects of designing and measuring antennas. The course is divided into two different parts: Antenna Design and Antenna Measurement (course main topics). Students are also going to be taught about Smart antennas and signal processing with antennas (special topic, with invited professors). In the Antenna Design Part, students are going to deal with
This lesson is from a variety of online tutorials developed for the Virtual Machine Shop. This module explores the subject of measurement. Linear and angular measurement is discussed and the inch and metric systems of measurement are compared. The uniqueness of the machine shop fraction is reviewed and examples of pronunciation are given. Animations and sound clips are provided to enhance the user experience. Users will have access to library, menu, previous, and next links to navigate throughou
Measurement: The Foundation of Chemistry
The distinction between accuracy and precision and its importance in commerce and science are explained. Numerous examples of real world use of chemical measurement are shown. Various equipment is used to demonstrate specific levels of precision.
Pulsus Paradoxus Measurement
This animation demonstrates the pulsus paradoxus.
Indirect Measurement and Trigonometry
Learn how to use the concept of similarity to measure distance
indirectly, using methods involving similar triangles, shadows, and
transits. Apply basic right-angle trigonometry to learn about the
relationships among steepness, angle of elevation, and
height-to-distance ratio. Use trigonometric ratios to solve problems
involving right triangles.
Investigate the difference between a count and a measure, and examine
essential ideas such as unit iteration, partitioning, and the
compensatory principle. Learn about the many uses of ratio in
measurement and how scale models help us understand relative sizes.
Investigate the constant of proportionality in isosceles right
triangles, and learn about precision and accuracy in measurement.
Musical Games (All Levels)

GPS Measurement Protocol
The purpose of this resource is to determine the latitude, longitude, and elevation of your school and of all your GLOBE sites. The GPS receiver will be used to determine the latitude, longitude and elevation of your school or of your GLOBE sites.
This two-part activity provides an introduction to the basics of measurement (linear, mass, volume, density) and discusses the role of inferential statistics in comparing any two measurements. The concept of random variations in measurements is introduced.
Carrot Sticks or French Fries? Analyzing Factors That Influence Interest Levels in Fast Food
In this lesson, students investigate the influence of fast food brand names on food choices and analyze the factors that contribute to branding preferences. Then they write an opinion essay on the corporate responsibility to influence food choices.
Tracheid Length Measurement in Selected Conifer Species
This exercise illustrates the techniques for macerating wood and staining, mounting, and measuring tracheids. Mean tracheid length is different in different species of conifers; therefore, this laboratory can be expanded into a larger scale comparative measurement exercise.
