Answer:
It consists of aggregates of facts:
In the plural sense, statistics refers to data, but data to be called statistics must consist of aggregate of certain facts. A single and isolated fact or figure like, 60 Kgs. weight of a student or the death of a particular person on a day does not amount to statistics.
EG
A statistic is a characteristic of a sample. Generally, a statistic is used to estimate the value of a population parameter. For instance, suppose we selected a random sample of 100 students from a school with 1000 students. The average height of the sampled students would be an example of a statistic.
