Which reliability test is suitable for the rating scale The reliability of parallel forms is similar to half-developed reliability, but there is a small difference: if you want to use several different versions of a test (for example.B. to prevent respondents from repeating the same answers from memory), you must first make sure that all questions or metrics provide reliable results. If possible and relevant, you should statistically calculate reliability and include it with your results. A series of questions are formulated to measure financial risk aversion among a group of respondents. Questions are randomly divided into two sentences, and respondents are randomly divided into two groups. Both groups take both tests: group A takes test A first and group B takes test B first. The results of the two tests are compared and the results are almost identical, which indicates the high reliability of parallel forms. There are two forms of testing, A and B, with a total of 13 items per test. The score is based on allowing up to 3 points per article, which gives 39 the highest possible score. The reliability of parallel shapes measures the correlation between two equivalent versions of a test. You use it if you have two different assessment tools or phrases designed to measure the same thing. They develop a questionnaire to measure the IQ of a group of participants (a trait that probably won`t change significantly over time).
They perform the test on the same group of people two months apart, but the results differ significantly, so the reliability of the IQ questionnaire is low. Written material is good for any researcher who wants to measure their test or research method. A good grade towards the formal stage As the name suggests, the technique uses two parallel forms, A and B, and these are given to the same group, one test following the other immediately or fairly quickly. A group of normal five-year-olds were selected and received Form A. Then, the next day, they received Form B. The attached table presents the data and the calculation scheme for the reliability coefficient. Split reliability: You randomly divide a set of measures into two sets. After testing the entire respondent, calculate the correlation between the two sets of responses. Suppose that the values of 100 people on two equivalent forms « A » and « B » of a « word fluency test » are correlated. Interracter reliability (also known as interobserver reliability) measures the degree of agreement between different people observing or evaluating the same thing. They use it when data is collected from researchers who assign grades, grades, or categories to one or more variables.
Example: You want to find reliability for a mathematical comprehension test, so create a set of 100 questions that measure this construction. They randomly divide the questions into two sentences of 50 (sentence A and sentence B) and handle these questions at intervals of one week for the same group of students. Steps: We illustrate the calculation and interpretation of the reliability of parallel shapes using another example using Sprinthall. These techniques are called internal consistency technique because, in this case, it evaluates the consistency that occurs in the test and not between two administrations of the same test or a separate administration of alternative forms. To label shapes as « parallel, the observed score must have the same mean and variances. If the tests are only different versions (without the « equality » of the observed results), they are called alternative forms. In the parallel form method, two equivalent tests in that they contain the same types of elements with the same degree of difficulty, but not the same elements, are administered to the same people. This technique is also known as the equivalent forms method.
Many factors can affect your results at different times: for example, respondents may experience different moods or external conditions may affect their ability to respond accurately. For example, run test A for the 20 students in a particular class and write down their results. Then, maybe a month later, run test B on the same 20 students and also note their results on that test. The reliability of parallel forms can help you test constructions. It`s important to consider reliability when planning your research design, collecting and analyzing your data, and writing your research. The type of reliability you need to calculate depends on the type of research and your methodology. The process of calculating the reliability of parallel forms is as follows: A team of researchers observes the progress of wound healing in patients. .
