The assignment involves analyzing a dataset of 10-15 whole numbers, either collected personally or sourced from reliable online resources. The overarching goal is to demonstrate a comprehensive understanding of basic statistical procedures by calculating key measures and interpreting the distribution. This exercise not only enhances data handling skills but also fosters critical thinking about the nature of data distributions, with particular attention to their symmetry or skewness, which has practical implications in health disparities and access to healthcare among underserved populations in the United States.

First, I collected data on the ages of residents within a community health clinic's catchment area. The ages ranged from 20 to 70 years, with the following values: 22, 25, 29, 35, 38, 41, 45, 50, 55, 60, 65, 70, 30, 40, 55. This dataset was chosen because age distribution can influence healthcare access and outcomes, especially among underserved populations, highlighting the importance of tailored interventions. To analyze this data, I first calculated the sample mean, median, and range. The mean age was computed by summing all values (550) and dividing by 15, resulting in a mean of approximately 36.67 years. The median, the middle value when data is ordered, was 40 years, providing a measure less affected by extreme values. The range, the difference between the maximum and minimum, was 70 - 22 = 48 years, indicating the spread of ages in the sample.

Next, I calculated the sample variance and standard deviation to assess the dispersion of ages. The variance was derived by subtracting the mean from each data point, squaring the result, summing these squared deviations, and dividing by n-1 (14). This involved measuring how much each age deviates from the mean, squaring these deviations, and averaging them (corrected for sample size). After performing the calculations, the variance was approximately 349.57, and the standard deviation, the square root of the variance, was approximately 18.70 years. These figures reveal the degree of variability in ages within the community.

To understand the distribution further, I evaluated the percentage of data within one and two standard deviations of the mean. For data within one standard deviation (36.67 ± 18.70), the interval was approximately 17.97 to 55.37 years. The data points falling within this range were 22, 25, 29, 35, 38, 41, 45, and 50 (totaling 8 values). Therefore, approximately 53.33% of the data points fell within one standard deviation. For the range within two standard deviations (36.67 ± 37.40), the interval extended from -0.73 to 74.77 years, which encompasses all ages in the dataset, totaling 15 data points. Hence, about 100% of the data falls within two standard deviations.

To visualize the distribution, I divided the data into five equal intervals that ranged from 20 to 75 years and created a frequency table. The intervals were 20-29, 30-39, 40-49, 50-59, and 60-75. The frequency of ages in each interval was 3, 3, 3, 3, and 3, respectively, indicating a uniform distribution across these ranges. Using these frequencies, I constructed a histogram illustrating the frequency distribution. The histogram appeared relatively symmetrical, with a bell-shaped pattern around the middle intervals, suggestive of a normal distribution. This symmetry indicates that the age data does not show skewness, which is consistent with the analysis of the percentage within standard deviations.

Based on the visual inspection of the histogram and the calculations of data dispersion, I conclude that the age distribution in this sample appears to be approximately symmetrical and resembles a normal distribution. This symmetry suggests that healthcare needs and access issues are evenly spread across different age groups, although further analysis with larger datasets would be necessary for more definitive insights. Understanding data distribution helps in designing targeted interventions for underserved populations, especially when age is a relevant factor influencing healthcare access disparities.
