Based on the “National Cancer Institute Data,” it is possible to provide sets of Central Tendency’ and Variation’s measurements for each of the race/ethnicity groups. To the first group of measurements belong Mean, Median, and Mode. Mean equals to 43,275, 38,5125, 70,06875, 31,49375, and 62,725 for American Indian / Alaska Native, Asian / Pacific Islander, Black, Hispanic, and White races respectively. It means that average rate per year from 2000 to 2015 was as mentioned above, and the number of cancer cases among Hispanic individuals is more than two times less than among Black ones. Median equals 43,85, 38,9, 71,4, 32,1, and 64,55 respectively, that means that middle number of a batch of data for Black individuals is also twice higher than for Hispanic ones. Mode, that is the most frequency occurring number from a batch equals to 36,6, 34,1 and 65,8 for second, fourth and last races respectively, as for others no repetition was detected.
The range, that is difference between maximal and minimal values, equals 19,7, 7,8, 21,6, 9,0, and 15,6 respectively, and it shows that for Black individuals changes in rates’ values are more noticeable than for Asian ones. Variance, or the average of squared deviations, equals 27,72, 5,68, 45,43, 8,4, and 26,16 and means that for second and fourth races data is less significantly spread. Simultaneously, standard deviation equals 5,26, 2,38, 6,74, 2,9, and 5,1 respectively. Therefore, individuals that belong to Black race is more likely to have cancer than Asian or Hispanic ones.
