Measurements of central tendency are statistical measures that categorize single values as descriptive of an entire allotment (Gravetter FJ, Wallnau, 2000). They submit to the hypothesis that there is one figure that best sums up the complete collection of measurement. The main function of central tendency is to provide accurate descriptions of sets of data and is mainly displayed as median, mean or mode. According to Sundaram et al. (2010), a large amount of people use mean because of its mathematical qualities, and is paramount for data distributed across ranges. A summary conducted to guide this study reveal that in their research, Van Voorhees and his colleagues used mean of 2 to explain participant’s completion of internet-based lessons. This means that the numerical digit 2 represented the number of lessons attended by each member of the sampled data. The mean is a representative of the average number representing a whole sample. It is the computation of all measurements, divided by the number it represents. Similarly, I can use measurements of central tendencies to test my hypothesis by calculating the mean of participants who would likely to seek medical healthcare.

This method differentiates between inter-individual variables and operates in tests taken under different conditions and times, or whose subjects display diverse characteristics (Dawson &Trapp, 2004).
