In determining a binomial the statistical significance of the values obtained, distribution was assumed with success defined as ranking mathematics either 1 or 2, and failure defined as ranking mathematics either 3 or 4. In some cases several parents chose to rank two or more subjects equally. For these cases a mean rank was determined for the subjects involve Each mean rank of 2h was scored as one-half of an individual ranking the subject as either 1 or 2, and one-half of an individual rank ing the subject as either 3 or 4. Assuming the four possible rankings of mathematics were equally probable, the probability of ranking mathematics as either 1 or 2 was one-half. The expected number of successful responses to any one statement was obtained by multiplying
The probability of success by the total number of possible responses. For the purpose of computation the normal approximation to the binomial distribution was employed. In Table 3 all entries, except for those specially noted, were significant at the 0.1 level. In Table 4 entries which were significant at the .01 level or .05 level are specially noted.
