How will you establish the reliability of your instrument?
Reliability can be assessed with the test-retest method, alternative form method, internal consistency method, the split-halves method, and inter-rater reliability. Test-retest is a method that administers the same instrument to the same sample at two different points in time, perhaps one year intervals.
How can reliability be improved?
Implementing a method that reduces random errors will improve reliability. However, the entire result of the experiment can be improved through repetition and analysis, as this may reduce the effect of random errors.
