Purpose: The purpose of this study is to propose a solution to the case where V50 calculation is impossible in the process of bulletproof test. Methods: In this study, we proposed a V50 estimation method using logistic regression analysis. Six scenarios were applied by combining the homogeneity of the sample and the speed range. Then, 1,000 simulations were performed per scenario and six assumptions reflecting the reality were applied. Results: The result of the study, it was confirmed that there was no statistical difference between the V50 value calculated by the conventional method and the V50 value calculated by the improvement method. Therefore, in situations where V50 can not be calculated, it is reasonable to use logistic regression analysis. Conclusion: This study develops a methodology that is easy to use and reliable by using statistical model based on actual data.
