Abstract: This study examined the performance outcomes between two tests of
manual dexterity, the Minnesota Rate of Manipulation Test [1] and the Minnesota
Manual Dexterity Test (1981). Even though the tests are constructed differently
and are different versions of the Complete Minnesota Dexterity tests, both
tests utilize the same instruction manual and the same normative data. The
researchers measured 233 random participants at a Midwestern international
airport and in the student center at a local university in Indiana. Each
participant completed three trials of a subtest on both versions of the test.
One sample t-tests on difference scores indicated statistically significant
differences on outcomes of both subtest comparisons as well as overall test
score differences (p < 0.000). These significantly different outcomes on the
two tests illustrate the need to establish separate normative data on the
latest version of the test, the Minnesota Manual Dexterity Test.
