The purpose of this study was to comparatively analyze normal gait on the plains by gender for old people reference data for the normal gait pattern for the old people. Participants were selected according to the Korean standard body type provided by the Ministry of Health and Wel-fare and used a three-dimensional motion analysis system. Cortex, Or-thotrak, and Excel were used as the software for analyzing the extract-ed data, and IBM SPSS Statistics ver. 24.0 was used for statistical anal-ysis. When data standardization was performed using the dimension-less numbers conversion, the step length and stride length of the lower extremities, which had differences between genders before dimension-less numbers conversion, showed no difference after dimensionless numbers conversion. Cadence, step time, and single support time of the left lower extremity, which had no difference between genders before dimensionless numbers conversion, were found to have significant dif-ferences after dimensionless numbers conversion. In addition, as a re-sult of analyzing the coefficient of variation value to find out the degree of change in data due to dimensionless numbers conversion, there were increase and decrease in the coefficient of variation value rang-ing from -8.11% to 6.67% before and after dimensionless numbers con-version, which means dimensionless numbers conversion can affect the statistical test.
