Description
Under the 'Statistics' tab, the collected results can be analyzed. Remindo will hereby calculate the Cronbach's alpha, a statistical value that indicates the reliability of a test. An explanation of Cronbach's alpha can be found in the article Statistical values.
There are two choice options available for analysis.
-
The first is to analyze questions used in the most recent test-taking. This analyzes the questions from most recent test-taking. These are the question versions offered to the last candidate who took the test. It is possible to supplement this with a time period, in order to indicate over which time frame the results should be included.
-
The second option is analyze a specific selection of questions. This option allows you to indicate which question versions should be included in the analysis. After selecting this option, a list will appear. This list can indicate which questions should be included in the analysis. Select the question versions which you want to add to the analysis. Again, a period can be entered from which the results should be included.
After selecting the desired option and period, the Cronbach's alpha can be calculated by clicking the button at the bottom right of the screen.
Warning!
When asked to calculate results over a long period of time, not every candidate who took this test will have answered the exact same question version and/or question set. Remindo will “add” data for this purpose. As a result, Chronbach's alpha will be less accurate and reliable. A notification of this will be given, see the yellow box in the image under 'Example'.
Example
The above example shows the outcome of an analysis. A graph appears with a number of levels, each indicated by a color. It is strongly recommended that at least the confidence level be 0.6 or higher. There is no limit on the number of analyses, so it is important to test regularly.
