| Abstract: | Objective To investigate an algorithm for analysis of variance （ANOVA） based on mean and standard devi- ation, and to try to write a SAS program for it. Methods Generating the formulas for ANOVA based on mean and standard devi- ation through mathematical deduction, and writing a pithy SAS program for the calculation. Results The algorithm for ANOVA based on mean and standard deviation was generated successfully, and a SAS program was developed. Conclusion It is feasible to obtain an ANOVA procedure using mean and standard deviation. Compiling the relevant SAS program is effective and reliabe for the calculation. |
