Measures of central tendency are also called measures of central location because they are single values that tends to describe a given set of data by identifying their central locations.In his book introduction to statistical methods and data analysis‚ R. Ott Longnecker argues that measures of central tendency seek to describe the centre of distribution of measurements and also how the measurement vary about the centre of distribution.Central tendency measures include mean‚ mode nd median.On the

success thus‚ we can think of those variables as of an ordinal nature. Ordinal data however‚ cannot be measured therefore‚ if we are to construct a survey that would answer particular questions on a Likert scale of ten points‚ we would be able to measure and therefore treat the variables as interval variable so that we can statistically analyze our data. According to (Miles‚ 2010 pp. 8)‚ asking for a subjective evaluation of a particular element may render the measurement as ordinal rather than interval

Statistics is the study of the collection‚ organization‚ analysis‚ interpretation‚ and presentation of data.[1][2] It deals with all aspects of this‚ including the planning of data collection in terms of the design of surveys and experiments. In mathematics‚ a graph is a representation of a set of objects where some pairs of the objects are connected by links. The interconnected objects are represented by mathematical abstractions called vertices‚ and the links that connect some pairs of vertices
