When are pivot tables used?
Usually when we create an Excel document, we have an idea of the basic structure for data that is the types of tables we like to use on the charts we’d like to see.
It is interesting to note that a pivot table is not of much use when analyzing data that we have already atomized into various tables across our worksheet(s).
For example we’ve all seen sba’s that provide a summary for a budget for some event, or personal expenses. Because we have an understanding and an intent when we create the budget, we would have all the ready broken our data into tables that show income and expenditures which probably include actual values and estimated values. This data is already mostly summarized and it may be useless to apply a pivot table that gives us any additional insight to what we already know.
Pivot tables are most useful when we have:
- a large set of unknown or unfamiliar data.
- Data that has redundancy (data that is un-normalized)
In practice pivot tables are usually used on operational data that is highly detailed for atomized and recorded frequently.
Why are pivot tables used?
When we have a set of unfamiliar data we can use a pivot table to generate many intermediate summary tables that’s a low for us to start making sense of Trends in the data so that we may:
- Determine how best to structure the data and
- Make strategic decisions from what the data tells us
