Coming back to the difference, STATISTIC is the score of each individual or a singular data. STATISTICS is therefore, the process of designing, comparing, interpreting and analysing data. Statistics is concerned with the sample and not the population as population is almost impossible to reach.

But there is no rule which prohibits the vice versa use which means that Mean can also be used in Arithmetic and Avg if used in Statistics can not be termed as wrong.
