1: Asians:
The distribution of ages among Asians in the dataset is symmetrical, as evidenced by a median of 35.0 and a mean of 36.48. The dataset displays a moderate level of dispersion, as indicated by a standard deviation of 12.21. The variance, calculated as 149, signifies a notable degree of variability in the age distribution. A skewness of 0.26 indicates a slight rightward tail, suggesting that there is a minor asymmetry towards higher age values. Additionally, the kurtosis value of -0.79 implies that the distribution has flatter tails compared to a normal distribution, indicating a relatively less peaked distribution.
2: Blacks
The age distribution of Black individuals in the dataset exhibits a right-skewed pattern, as reflected by a median of 31.0 and a mean of 32.74. The dataset’s dispersion is of moderate extent, as evidenced by a standard deviation of 11.34 and a variance of 128.62, indicating variability in the distribution of ages among Black individuals.
The positive skewness value of 1.01 further characterizes the distribution. Skewness measures the asymmetry of a distribution. In this context, a positive skewness of 1.01 suggests a tail extending towards higher age values. This implies that there are relatively more Black individuals with ages higher than the median, contributing to the rightward skew.
Moreover, the positive kurtosis value of 0.99 is indicative of the distribution having heavier tails and a more peaked shape compared to a normal distribution. Kurtosis measures the tail heaviness of a distribution. In this case, a positive kurtosis suggests that the tails of the age distribution among Black individuals are more pronounced than those in a normal distribution, and the overall shape of the distribution is more concentrated around the mean.
