With the factors concerned with educational environments encompasing mothers, number of brothers and sisters, the mother's educational history and wether the mothers work or not high correlation was shown. 3. Among the factors concerned with character analysis, emotional stability, if children can control themselves or not had considerable effect. 4.

With the factors concerned with educational environment including mothers, the mothers' educational history, the number of brothers and sisters, birth order were highly reliable. 6. With the factors concerned with character analysis, emotional stability, if children are degenerative or productive showed high reliability. 7. Multiple correlation coefficient for all the 27 factors was 0.823, which was found to be highly reliable for the estimation of the frequency of training.
