Answer:
In any research, enormous data is collected and, to describe it meaning fully, one needs to summarise the same.The bulkiness of the data can be reduced by organising it into a frequency table or histogram. [1] frequency distribution organises the heap of data into a few meaningful categories collected data can also be summaried as a single index/value, which represents the entire data these measures many also help in the comparison of data
CENTRAL TENDENCY
central tendency is defined as “the statistical measure that identifies a single value as representative of an entire distribution ”.[2] it aims to provide an accurate description of the entire data. It is the single value that is most typical /representative of the collected data. The term “number gunching ”is used to illustration this aspect of data description. The mean, median and mode are the three commonly used measures of central tendency
MEAN
mean is the most commonly use measure of central tendency. There are different types of mean, viz. arithmetic mean, weighted mean, geometric mean(GM) and harmonic mean (HM) If mentioned without on adjective (as mean), it generally refers to the arithmetic mean.
