Units of measurement

Test-retest reliability can be a useful assessment for a survey instrument. “Test-retest reliability provides information on how consistent a measure is when it is administered twice in a relatively short time frame. The appropriate length of that time frame will vary with both the instrument and the target population” (Krysik & Finn, 2013, p.266). In addition, the interval needs to be extended so that the subject cannot recall the answers and short enough to make sure that no changes occur in…

A constant question to go through a student’s mind is do grades really matter? The often happens when times get tough and grades are the main reason why students get stressed. Most parents think that grades are the key towards an accomplished future overall. Do grades really determine our future? Should we stress them more? Is this a proficient system?

controlled conditions indoors and the sit and reach test is a field based tests though it can be performed indoors too. When testing the validity of the sit and reach test it is hard to be accurate with the results because other factors such as the measurement or the individual’s arm length can play a vital role when it comes to the validity.

important for professionals who use psychological testing. With that being said, the method attributes the consistency of the test measurements and excludes chance and nonessential factors in the outcome (p. 89). On the other hand, Hays defines that validity compromises the relevant and applicable inferences that are made by the instrument. In fact, these sales of measurements are like a variety of tools…

in behavioral measurement? Validity measurement is important, because it measures the target behavior, measures the duration of the target behavior and any questions that are directed towards that behavior. Validity also makes sure the data was tracked at appropriate times and are relevant to the target behavior(Cooper, Heron & Heward, 2007, p. 103). If none of these elements add up, then the resulted data is compromised, therefore the data is meaningless. Reliability measurements are based…

the metric system of measurement. The Metric System is a measurement system that is based on the number 10 and used in most countries including most of Europe, Japan, China, and many other nations. The United States uses the Standard system. The Metric system uses degrees Celsius instead of Fahrenheit. For example, zero degrees Celsius is 32 degrees Fahrenheit, which is the freezing temperature of water. That is not the only difference between the two, though. Distance measurement between the…
