NOTE. - If speed and accuracy tests on the use of fractional parts are desired, Examples 11-20 can be used for one test, Examples 31-40 for the second test, and Examples 41-60 for the third. In each case, obtain and record for future use the median time and the median accuracy for each test. If miscellaneous arrangement of the three kinds of examples is wanted, and that in most cases will prove desirable, do, on one day, Examples 1, 21, and 41; on another day, Examples 2, 22, and 42.
