Statistical test results with Chi-Square obtained р_value 0.021 meaning α <(0.05) so there is a significant relationship between light activity and the incidence of premenstrual syndrome in young women. The Chi-Square statistical test obtained a р_value of 0.155 meaning α > (0.05) so that there is no significant relationship between moderate activity and the incidence of premenstrual syndrome in young women. The Chi-Square statistical test obtained a р_value of 0.264 meaning α > (0.05) so there is no significant relationship between strenuous activity and the incidence of premenstrual syndrome in young women.
