Conclusion: In the context of combined health and economic crises, mental health outcomes are not equally felt by women. Material and methods: A quantitative, non-experimental, descriptive and correlational design was used. Treatment characteristics included type of athletic training service, duration, amount (eg, number of visits), and direct cost of care. To resolve the problem, another method of assessing normality using skewness and kurtosis of the distribution may be used, which may be relatively correct in both small samples and large samples. Although there are various methods for normality testing, Figure 4: Boxplot showing distribution of the mean arterial pressure, Figure 1: Histogram showing the distribution of the mean arterial pressure, Figure 2: Normal Q–Q Plot showing correlation between observed and, expected values of the mean arterial pressure, Figure 3: Normal P–P Plot showing correlation between observed and, expected cumulative probability of the mean arterial pressure.
