Test process organization model

Test duration is an important factor in updating the quality of results. Test tasks. Student response time is a random variable. As a result of processing, a large set of experimental data was obtained. The response time of students is a random variable, the duration of the test is determined and depends on the complexity of the test. To describe the obtained dependence and implement the results, the coordinate transformation is proposed. The input function has the meaning of the inverse time and determines the time remaining until the end of the test. On the basis of statistical analysis it was found that this random variable - the time until the end of the test, is a subject to exponential law. In order to provide the practical usage of the study results, in conclusion you can find a ratio that allows you to set the acceptable value of the test duration to objectively assess the quality of student’s knowledge from his subject area.
