Hello, I am looking for someone to write an essay on Define. It needs to be at least 500 words.
When split-half method is used the questions on the examination tool that are testing for the same skills or ability are divided into two halves and the test is administered (Gullo, 2005). The results are then checked with the statistical method of correlation and higher level of correlation exhibits that the test is reliable. When the Kuder-Richardson method of testing reliability is used one tools of examination is administered and student’s scores are analyzed for reliability with the help of different formulas (Oermann, 2014). Inter-Rater method of reliability testing is used to measure the consistency of how different examiners score students on the scores of the same examination tool (Kern, 2010). One way of doing this is by analyzing how two different raters rate the scores they have assigned to students on the same test.
