Difference in average ages – black people versus white people shot by police: October 18
Today I have gone through the statistical analysis of the age distribution for people killed by police, comparing black and white populations. Here’s a summary that i have undergone about the data.
Overview: The analysis focuses on the age distribution of individuals killed by police, specifically comparing black and white populations.
Black Population:
-
- About 68% of ages for black people killed by police fall within one standard deviation of the mean (between Mean – Standard Deviation and Mean + Standard Deviation).
- The mean age is between 21.29 and 44.3White Population:
- Similarly, about 68% of ages for white people killed by police fall within one standard deviation of the mean (between Mean – Standard Deviation and Mean + Standard Deviation).
- The mean age is between 26.70 and 53.26
- Based on the analysis suggestion that white individuals killed by police are statistically significantly older, on average, than black individuals.
- Visualizations, such as smooth histograms, show the differences in age distributions between black and white populations.
- The text mentions the challenge of using a t-test due to deviations from normality in age distributions.Conclusion:
- The mean age of white individuals killed by police is noted to be almost 28.
