Analysis of Descriptive Statistics for Cancer Incidence Data

This report provides an analysis of cancer incidence data using descriptive statistics. The study focuses on data from the National Cancer Institute, calculating mean, median, mode, variance, standard deviation, and range for different racial and ethnic groups. The analysis reveals variations in cancer incidence rates, with the Black race exhibiting the highest average incidence and the Hispanic race showing the lowest. The report also discusses the dispersion of data, noting that the Black race has the highest range of incidence, while the Asian/Pacific Islander and Hispanic races show less variation. Furthermore, the report compares the mean and median values to assess data skewness and highlights that the American Indian/Alaska Native race has relatively high cancer incidence rate. This detailed analysis provides insights into the differences in cancer incidence across various groups, which can inform healthcare professionals regarding research, treatment options, and patient education.

The respective descriptive statistics pertaining to the various groups is shown below.
From the above descriptive statistics, it is evident that there is significant difference in average
incidence of cancer across races. The highest rate is observed for black race which has an
incidence that exceeds 70 per 100,000 person. The cancer incidence rate for white race is also
higher than other races but lower than black race. The lowest average incidence amongst the
given five races is visible in Hispanics (Eriksson & Kovalainen, 2015). Comparing the mean
values with the corresponding median, it is evident that the deviation is quite small only which
indicates that the there is no abnormally high or low incidence rate in terms of cancer that is
observed for any of the years for any particular race (Hillier, 2016).
In terms of deviation, lowest values are seen for Asian/Pacific Islander race which implies that
over the years there has not been a significant change in the incidence rate of cancer in this race.
Another race which has similar observation is Hispanic rate which has witnessed low incidence
rate of cancer and over the years shown little variation. The situation is quite contrasting for
Black race which not only has the highest average incidence rate but this rate has shown the
highest dispersion over the years. The range of incidence for this race is highest. However, if the
average value is considered, then relative variation is cancer incidence is quite high for American
Indian/Alaska Native race (Flick, 2015).
