การพัฒนาโปรแกรมคอมพิวเตอร์ในการเลือกใช้เทคนิคทางสถิติที่เหมาะสมและการกำหนดขนาดตัวอย่างสำหรับการวิจัยทางสังคมศาสตร์ / ธีระวัฒน์ สุขีสาร = A development of the computer program for selecting the appopriate statistical techniques and determining sample size in social science research / Thirawat Sukheesan
The purpose of this research was to develop a computer program for selecting the appropriate statistical techniques and determining sample size in social science research. The research and development processes were : problem identification, problem analysis, computer program design, computer language selection and program writing, testing of program functioning and improving program, manual writing and computer program evaluation. Visual Basic language version 5.0 was used to write the program. The program was evaluated by 20 users with basic knowledge in statistics and social science research. The result of this research and development was the computer package program which was separated into 2 subprograms : 1. program to selecting the appropriate statistical techniques in data analysis according to analysis's purposes or research questions. That is to describle the population or sample, explanation of relationships or prediction, test the difference between populations, organize the systems or relationship structures of group of variables and to find the causal relationship 2. program for determining sample size in both descriptive research or survey research and the experimental research. The result form the program evaluation, the users showed that the program evaluation, the users showed that the program was efficient in both speed and accuracy and useful for social sciences research in selecting statistical data analysis techniques and in determining the sample size.
