Following their observations of teacher-child interactions, CLASS® observers rate each dimension on a 7-point scale, from low to high. Although measurement is an important part of everyday life, kids don't automatically understand that there are many different ways to measure things. the difference between two consecutive points on the scale are equal over the entire scale. Jan 19, 2021 - Chapter Notes - Chapter 7 - Test and Measurement in Sports, Physical Education, Class 12 | EduRev Notes is made by best teachers of Class 12. Although it is perfectly natural to think about length, area, volume, temperature, and weight as attributes of objects that we measure, a little reflection will produce many other measurable quantities: speed, loudness, pressure, and brightness, Test and Measurement in Sports class 11 Notes Physical Education. and 12 cm. Protection CTs accuracy is not important as measurement CTs. Easy to understand – Diagrammatic data presentation makes it easier for a common man to understand the data. Details of Knee Point Voltage: Every Protection class CT Name plate contains details of Knee point voltage as shown in below figure. It is a type of variable measurement scale. 5.4m 6.2m 12.7m 3m 7.6m 0.54m 0.3m 540cm 620cm 1270cm 300cm 760cm 54cm 30cm x100 Try changing these measurements in metres into centimetres 42. They require accuracy up to many times rated current, so they made with Grain oriented silicon steel with high saturation flux density. Diagrams are usually attractive and impressive and many newspapers and magazines use them frequently to explain certain facts or phenomena.Modern advertising campaigns also use diagrams. It possesses the character of the origin or zero points. CBSE quick revision note for class-11 Mathematics, Physics, Chemistry, Biology, and other subject are very helpful to revise the whole syllabus during exam days. Meaning and Importance Measurement is important because it helps us to quantify the world around us. The ratio scale has a unique feature. CBSE Class 11 Revision Notes and Key Points. Scores of 1-2 mean the quality of teacher-child interactions is low. For example, fossil fuels are essential to generate energy, mineral resources are important for industrial development, etc. is equal to the difference between 11 cm. Measurements play an important role in daily life because they are useful to do basic tasks, such as take a child's temperature with a thermometer, make time estimations, measure out medicine and find weights, areas and volumes of different materials or substances. This document is highly rated by Class 12 students and has been viewed 106670 times. and 7 cm. CLASS® is scored by trained and certified observers using a specific protocol. A measurement is the action of measuring something, or some amount of stuff. It allows researchers to compare the differences or intervals. Advantages of Diagrammatic Data Presentation. Resources are important for the development of any country. MEASUREMENT OF … In other words, the intervals of the scale i.e. A standard unit of measurement provides a reference point by which objects of weight, length, or capacity can be described. This consistency of intervals is lacking in two previous level of scale. Necessary to conserve resources because: (i) Their irrational consumption and over utilisation have led to socio-economic and environmental problems. The ratio scale is the 4 th level of measurement scale, which is quantitative. In the ordinal level of measurement, the variables are still classified into categories, but these categories are ordered and there is no equivalent distance between the categories. So it is important to measure certain things right, distance, time, and accuracy are all great things to measure. Eg: class variable for a person can have values like upper class, lower class, middle class etc. For example, the difference between 6 cm.
