Introduction
Descriptive statistics provide valuable insights into the fundamental characteristics of a dataset. This report presents a descriptive statistical analysis of a sample dataset concerning gender distribution, ethnicity, recall scores, and age demographics of participants. Using various measures of central tendency and frequency distributions, this report elucidates the particulars of the dataset, providing a foundation for further analysis.
Gender Distribution
As illustrated in the dataset, the gender distribution of the sample is as follows:
- Female: 36 (50%)
- Male: 36 (50%)
- Total: 72
This distribution reveals that the sample population is evenly split between female and male respondents. Such equality in gender representation can be crucial when assessing the impact of various factors on the wider community, as nondescript variable skewness may lead to biased outcomes (Rubin, 2019).
Ethnicity Distribution
The ethnicity breakdown of the respondents reveals the following frequencies and percentages:
- Caucasian: 31 (43.1%)
- African American: 23 (31.9%)
- Latino: 14 (19.4%)
- Others: 4 (5.5%)
From this data, Caucasians make up the largest ethnic group, while the "Others" category, which is significantly smaller, indicates a need for more comprehensive data collection on various ethnic backgrounds. The representation of diverse ethnicities is essential as it allows for more targeted approaches in interventions and programs to improve overall community health and social outcomes (Duncan et al., 2018).
Recall Scores
The recall scores gathered from a rating scale indicate the distribution of recall ratings across participants as follows:
- Rating of 5: 8 (11.1%)
- Rating of 8: 8 (11.1%)
- Rating of 9: 8 (11.1%)
It is interesting to note that frequent high ratings (5, 8, and 9) have the same proportion of respondents, suggesting that factors affecting recall ability, such as age and cognitive abilities, potentially influence how participants feel about their performance (Wang & Ritchie, 2017). The data indicates that a significant portion of the participants rated their recall ability highly.
Age Distribution
The distribution of ages in the dataset shows the following frequencies and percentages:
- Age 18: 0 (0%)
- Age 19: 0 (0%)
- Age 20: 0 (0%)
- Age 21: 0 (0%)
- Age 22: 0 (0%)
- Age 23: 6 (8.3%)
- Age 24: 8 (11.1%)
- Age 25: 6 (8.3%)
- Age 26: 5 (6.9%)
- Age 27: 6 (8.3%)
- Age 28: 0 (0%)
- Age 29: 7 (9.7%)
- Age 30: 0 (0%)
From this data, it is clear that the mode of the provided dataset occurs at age 24, with 11.1% of the sample belonging to this age group. The relationship between age and cognitive recall abilities has been emphasized in the literature, with findings suggesting that recall accurately increases with age up to a certain point, beyond which it might decline due to cognitive aging (Verhaeghen & Salthouse, 1997; McDaniel et al., 2010).
Analysis and Interpretation
The analysis highlights the importance of gender and ethnicity representation within study samples to avoid skewness. An equal gender representation is beneficial, indicating an unbiased view of outcomes across genders, allowing implications to be made regarding the broader population. In a multicultural society, acknowledging ethnicity diversity is essential for tailoring health interventions and policies to meet specific needs.
The recall statistics present an opportunity for future investigations while suggesting a correlation between respondents' perceptions of memory acuity and age demographics. Age seems to play a crucial part in cognitive abilities, primarily affecting performance. Given the peaks of recall scores within certain ages, targeted cognitive training and health programs could be beneficial, particularly for younger and middle-aged individuals, who often experience fluctuating recall capabilities.
Limitations and Further Research
Despite the insights provided, there are some limitations worth noting. The sample size of 72 is relatively small, restricting the generalization of the findings across a broader population. Future studies should explore increasing the sample size to enhance the reliability of findings. Moreover, including more diverse ethnicities and age groups could furnish a more comprehensive view of the population dynamics involved.
It would be beneficial for future research to examine interventions tailored to specific age brackets, which could lead to improved recall and cognitive function. This approach may provide insights into how aging impacts memory and allow for effective strategies to enhance cognitive health (Harrison et al., 2020).
Conclusion
This descriptive statistic report highlights not only the gender and ethnic distribution of the sample provided but also the cognitive recall abilities and age demographics of the participants. Understanding these characteristics forms the basis for engaging with a variety of stakeholders in health and education sectors for improving programs aimed at enhancing cognitive health. The study also emphasizes the need for more profound investigations into specific demographic impacts on cognitive functions and recalls.
