Data representation (day 15)
The data that we collected in the previous steps needs to be represented in a meaningful way for an effective analysis. This depends on the following factors:
- Type of data.
- Variation over a period of time: The entire data for a period is collected and the variation in the data is studied. The different time intervals for this period are irrelevant from this perspective (population data).
- Variation with time: This perspective involves looking at the data at different time intervals over a certain period (process data).
The following table provides a summary of the ways the different types of data can be represented.
