Biostatistics Report: Analysis of US Population Data (1999-2010)

This biostatistics report presents an analysis of US population data from 1999-2010. The study, based on a sample of 14,081 individuals, examines the distribution of various characteristics. The report includes descriptive statistics for race/ethnicity and education, calculating mean, median, and skewness, and visualizing the data with histograms and pie charts. The analysis reveals that the race/ethnicity data is positively skewed, while the education data is negatively skewed. The report also provides an overview of diabetes prevalence within the sample. The report offers valuable insights into the demographic composition and statistical properties of the data.

the race is 2924.2. The median or second quartile value of the race is 2786. The mode the
race does not exist, because there is no repetition in the data sheet. The standard deviation of
the data sheet is 2449.82. It has been seen that the mean is larger than the median. Hence the
Race/ ethnicity is skewed to the right that is positively skewed. The value of the skewness is
1.16.
