Estimating Reliability
Imagine that you are a test
developer and need to establish/estimate the reliability for your test. There
are a number of factors to consider when deciding upon the best method to
estimate reliability. As you read about in the textbook, some of these factors
are related to the test itself and what it measures (e.g., a stable trait, a
homogenous construct) (Cohen & Swerdlik, 2010). Which method for
establishing reliability do you think would be the most difficult in terms of
taking researchers a great deal of time and money). Which do you think would
take the least amount of these resources (time and money? Explain your
reasoning.
