What is the importance of validity, accuracy, and reliability 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 on measurements being consistent to one another. Basically saying measurements should yield the same value when the events are similar to one another. Reliability is consistent measurements(Cooper,

    Summary Of Uncertainty, Error, And Confidence '

    Carpi and Egger’s reading “Uncertainty, Error, and Confidence” discusses how there will always be a small portion of error in all scientist’s works. However, there are two different types of error: statistical and systematic and the main difference between the two is that statistical error is random and systematic error can be compensated for during an experiment. Scientists do not report just a single value as a measurement due to these types of errors in experiments, they report a certain range of values, which is a confidence interval. Another key aspect within the reading is in regards to uncertainty. Scientists must accept and realize that there will be errors within the measurements, thus a sense of uncertainty.…

    Scientific Notation

    Question 1 (i) Mean: ‘’The sum of a series of measurements (or numbers) divided by the number of those measurements.’’ (Open University,2015: S104 Exploring Science Glossary, Milton Keynes, The Open University). Scientific Notation: ‘’ A notation that represents any number by expressing it as a number that is equal to or greater than 1 but less than 10, multiplied by a simple power of ten where the index may be positive or negative. Thus, 1.30 × 103 is in scientific notation (because 1.30 is equal to or greater than 1 but less than 10, while 103 is a simple power of 10 where the index is positive). Note, though, that 13.0 × 102 and 0.130 × 104 are not in scientific notation.…

    Homeopathic Therapy Survey

    Homeopathic Therapy Survey Homeopathic therapy can be an alternative or an adjunct to current medical treatment of both acute and chronic diseases and medical processes. Most patients who try homeopathic therapy subjectively state the methods displayed efficacy (Pomposelli et al., 2016). However, unless providers are specifically trained in homeopathic methods, this genre of healthcare can be overlooked. More knowledge was desired of current medical providers’ thoughts on homeopathic medicine, therefore a survey to ascertain this information was created. The purpose of this paper is to explain the electronic survey purpose, explain the procedure for protecting survey participants, perform statistical analysis using SPSS, provide a breakdown…

    Assessment Strengths And Weaknesses

    2.3 I can assess the strengths and weaknesses in my final work Upon completion of my presentation I noticed a couple of changes that needed to make to improve my work to its full potential. The following things I noticed were: • My graph was too small so I upped the size to make easier to read as it was hard to read the smaller numbers on the axis. • My video was too long so I shortened the size of it to take up less space and to make it shorter and quicker to watch Additionally one of my peers noticed something on my PowerPoint that I can improve, this was: • Some of my hyperlinks on my contents were not working so I had to re-do them so that they went to the page to make it easier for the person using the PowerPoint, which is very helpful if they want to learn and read about one specific thing instead of having to go through each slide to get to the one they wanted to.…

    Reliability Of Standardized Testing

    Although there is an exuberant amount of research disproving that standardized tests are trustworthy and reliable, there are still people who stand behind it for multiple reasons. One reason as to why there are people and colleges who heavily trust the results of these scores is because so many kids take it, and according to statistical measures, the more people who participate in something, whether it be a survey or a test, the more accurate the yielded results are. Statistics states that in 2011, 1,666,017 students took the ACT and 1,664, 479 students took the SAT (Wikipedia). These massive numbers ensure that the test results produce generally accurate feedback that well represents the students that took the test. Another argument for the…
