Topics Learnt Today:
1: Hispanics
The age distribution of Hispanic individuals in the dataset demonstrates a moderately right-skewed pattern, as indicated by a median of 33.0 and a mean of 33.73. The data exhibits a relatively lower level of dispersion, evident through a standard deviation of 10.59 and a variance of 112.13, suggesting that there is less variability in the distribution of ages among Hispanic individuals.
The positive skewness value of 0.77 adds more detail to the distribution. Skewness measures the asymmetry of a distribution, and in this context, a positive skewness of 0.77 indicates a tail on the right side. This suggests that there are relatively more Hispanic individuals with ages higher than the median, contributing to the rightward skew.
Furthermore, the positive kurtosis value of 0.69 provides insight into the tails and overall shape of the distribution. Kurtosis measures the tail heaviness of a distribution, and a positive kurtosis of 0.69 suggests slightly heavier tails compared to a normal distribution. This implies that the age distribution among Hispanic individuals has tails that are more pronounced, and the overall shape of the distribution is somewhat more concentrated around the mean.
2: Native Americans:
The age distribution of Native American individuals in the dataset is characterized by a moderately right-skewed pattern, with a median of 32.0 and a mean of 32.92. The data exhibits a relatively narrow spread, as evidenced by a standard deviation of 9.38 and a variance of 87.92, indicating a lesser degree of variability in the distribution of ages among Native American individuals.
The positive skewness value of 0.50 provides additional insight into the distribution. Skewness measures the asymmetry of a distribution, and in this context, a positive skewness of 0.50 suggests a tail on the right side. This implies that there are relatively more Native American individuals with ages higher than the median, contributing to the rightward skew.
Moreover, the negative kurtosis value of -0.17 offers information about the tails and overall shape of the distribution. Kurtosis measures the tail heaviness of a distribution, and a negative kurtosis of -0.17 suggests slightly lighter tails compared to a normal distribution. This indicates that the age distribution among Native American individuals has tails that are less pronounced, and the overall shape of the distribution is somewhat flatter at the peak compared to a normal distribution.
