Decision making is the core and the heart of administration and administrative process both in theory and practice. It guides the administrative behavior to achieve the goals. To decide which of the effective alternatives to adopt among various and complex alternatives involves inevitably some extent of risks. Devision making depends heavily upon the abilities and risk taking level of the decision maker, because of his own incompleteness of knowledge, difficulties of anticipating events to be happen. This study intended to examine the variables influencing the selecting the alternatives to adopt under the condition of unpredictable events and their unanticipative consequences. The relationships between risk taking and the variables such as the personality dispositions, jobs, educational levels, and age were and age were analyzed respectively by statistical method. The results of the study were as follows: 1. The relationship between risk. taking and personality dispositions. In the risk levels when the risky alternatives and safe alternatives with the same gain-loss probability were presented to choose the one to the subjeects of this research. A. No significant defference between the high and the low score group in risk taking. B. No significant difference between the high and the low score group in emotional stability. C. No significant difference between the high and the low score group in selfsufficiency. D. No significant difference between the high and the low score group in selfcontrol. 2. The relationship between risk taking and jobs. Business, military, and police were high in risk taking while the educational finance were low in terms of mean score. Nonetheless, the statistical test proved the difference between the jobs negative. 3. The relationship between risk taking and schooling. The difference between those who received the higher education and those who did not were proved negative. The level of schooling and the level of risk taking were not correlated. 4. The relationship between risk taking and age. With regard to age difference, the young men were higher than the old man in choosing the safe alternatives rather than the risky ones. But none of the correlations achieved statistical significance. As the conclusion of this research, it might be said that the variables such as the job, personality, age, and schooling of the decision maker rarely influenced the level of risk taking in choosing the behavior alternatives to achieve certain goals. And the statistical analyses proved that the personaity dispositions like emotional stability, venturesomeness, self-sufficiency, and self-control were not correlated with risk taking, either.
