As part of today’s analysis, I looked at the age distribution between the White and the Black races. A combined kernel density plot is shown below for the ‘age’ variable of the ‘Black’ and ‘White’ races. The kernel density plot of the age variable for the ‘Black’ race (in red) indicates that it is positively skewed and moderately peaked. The statistical summary reveals that the dataset contains 1,725 individuals, with an average age of approximately 32.93 years and a standard deviation of about 11.39. The age range spans from 13 to 88 years, with quartile values indicating the distribution’s spread.
While the kernel density plot of the ‘age’ variable for the ‘White’ race (in blue) indicates a slightly negatively skewed and relatively flat distribution. The statistical summary reveals that the dataset encompasses 3,244 individuals, with an average age of approximately 40.13 years and a standard deviation of around 13.16. Age values range from 6 to 91 years, with quartile values providing insights into the distribution’s variability.
Additionally, the qq-plot indicates that the age distribution for both the ‘Black’ and ‘White’ races is not normal, which is an important observation for statistical analysis, as shown below.
Overall, these analyses provide a comprehensive view of age demographics within the two racial groups, revealing differences in skewness and shape of their age distributions.
