The Three‐minute Reasoning Test a Re‐evaluation
James R. Hartley, Frank W. Hogarth, Richard L. Mills · Educational Research · 1973
Summary In a previous paper (Hartley and Holt, 1971) the development of a three‐minute reasoning test was described, and its validity and reliability assessed. In this paper three experiments are reported which look in greater detail at these aspects of the test in different situations. The results of the experiments indicated that the test was less valid and was less reliable than was originally anticipated.
