# Youssef Ahmed's Number of Participants Evaluated in Study移动投注体育赛事
Youssef Ahmed, a researcher at the University of Technology, recently conducted a study to evaluate the number of participants in her research on the impact of social media on mental health. In this study, she collaborated with co-authors Dr. Farouk Al-Hayani and Dr. Aya Al-Khaleel to assess the demographic and psychosocial factors influencing mental health among participants. The study involved a total of 23 participants, drawn from a university in the United Arab Emirates.
The participants were divided into three age groups: students aged 18-25, working professionals aged 25-35, and older adults aged 35-50. Among these, 10 participants were students, 8 were working professionals, and 5 were older adults. The researchers used a five-point Likert scale to measure participants' perceptions of social media's impact on mental health, self-esteem, and depression levels. The mean score for mental health was reported as 7.8, with a standard deviation of 1.2. The mean score for self-esteem was 6.5,Primeira Liga Hotspots while the mean score for depression was 4.7.
The researchers compared the mean scores of the participants to those of the general population, which had a mean score of 6.0 for mental health, 5.5 for self-esteem, and 4.0 for depression. The results showed that the participants had significantly higher scores than the general population (p < 0.05). Additionally, the researchers conducted a statistical analysis using a t-test to determine the significance of the differences between the study and population means. The results indicated a statistically significant difference (t = 3.21, p < 0.0004), suggesting that the number of participants in the study had a positive impact on the mean scores.
The researchers also noted a positive correlation between the number of participants and the mean score, indicating that larger studies may yield better results. The correlation coefficient was found to be 0.78, with a p-value of 0.0001, indicating a strong and statistically significant relationship between the number of participants and the mean score. The confidence interval for the correlation coefficient was 0.78 ± 0.01, further supporting the significance of the findings.
In conclusion移动投注体育赛事, Youssef Ahmed's study highlights the importance of sample size in research. The findings suggest that larger studies with more participants are more likely to yield accurate and reliable results. Future research should focus on increasing the number of participants in future studies to ensure that the results are more representative of the general population.
