Measures of Central Tendency

Measures of central tendency are critical in the process of data analysis as they are important in showing the attributes of the variables used in the process. Some of the measures of central tendencies include mean, median, mode, maximum, minimum, frequencies, range, and standard deviation (Kaliyadan & Kulkarni, 2019). Descriptive statistics an also be applied in determining the normality of the data used as well as the viable procedures that ought to be undertaken in the process of data analysis (Amrhein, Trafimow, & Greenland, 2019). Descriptive statistics may also be used to make conclusion in the process of data analysis; however, much deeper approaches such as test of hypothesis are always required for accurate conclusions.

The tables given below indicate the descriptive statistics for the National Cancer Institute data presented in the excel spreadsheet. The data was analyzed through the application of the Microsoft Excel functions.

Table 1

American Indian / Alaska Native (Includes Hispanic)
Measures of Central Tendency Value
Median 43.850
Mean 43.276
Mode N/A

 

 

 

 

Table 2

Asian / Pacific Islander (Includes Hispanic)
Measures of Central Tendency Value
Median 38.910
Mean 38.522
Mode 36.600

 

Table 3

Black (Includes Hispanic)
Measure of Central Tendency Value
Median  71.423
Mean 70.068
Mode N/A

 

Table 4

Hispanic (Any Race)
Measure of Central Tendency Value
Median  32.100
Mean 31.494
Mode 34.100

 

Table 5

Hispanic (Any Race)
Measure of central tendency Value
Median 64.5510
Mean (average) 62.7252
Mode 65.8000

 

Table 1 to 5 indicates the descriptive statistics for different races involved in the cancer study. The data or figures were recorded for every 100,000 persons. From data analysis, it is evident that the black community had the highest rates of cancer infections with the White race coming second. The above scenario has been indicated by the median and mean. Recorded under each variables in the dataset. Also, from the descriptive analysis, Hispanics had the lowest rates of cancer infections from the study. The data used in the study was collected over a period of 16 years, from the year 2000 to 2016. The highest rate of cancer infection among African Indians was 51.7 while the lowest rates was recorded as 32.

Table 6: Measures of Variation

Ethnicity/Race     American Indian / Alaska Native (includes Hispanic) Hispanic (any race) Black (includes Hispanic) White (includes Hispanic) Asian / Pacific Islander (includes Hispanic)
      Variance 27.7190 8.3998 45.4290 26.1621 5.6792
Standard Deviation 5.2647 2.8984 6.7400 5.1151 2.3831
Maximum 51.7231 35.0001 79.0001 68.8001 41.8001
Minimum 32.0001 26.0001 57.4201 53.2001 34.0001
Range 19.7001 9.0002 21.6001 15.6001 7.8001

 

Table 6 given above shows the measures of variation for the descriptive statistics shown in table 1 to 5. From the analysis, the highest variation was indicated by the black race. In other words, the highest variation was recorded for the data under the black participants. The variation was recorded per every 100,000 persons for the study process.
