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.
For other uses, see Aggregate (disambiguation). In statistics, aggregate data are data combined from several measurements. When data are aggregated, groups of observations are replaced with summary statistics based on those observations. In a data warehouse, the use of aggregate data dramatically reduces the time to query large sets of data.
