Performing the evaluation is then the next phase. This can include descriptive analytics, such as calculating summary statistics to exhibit the central tendency within the data; time-series analysis to measure trends or perhaps seasonality in the data; and text mining or all-natural vocabulary processing to derive information from unstructured data.
Various analysis involve inferential analysis, which attempts to generalize results from an example to the larger population; and diagnostic analysis, which seeks out reasons behind an final result.
