Data analysis is the scientific process of establishing an objective meaning(s) from unprocessed/partially-processed information. Statistical data analysis is a major section of data analytics that is centred on making meaning of data that can be expressed in numerical terms. In other words, data-analysis is a value-addition process that makes otherwise useless data elucidative, descriptive, predictive or interpretive.
Statistics data analysis is mainly guided by the nature of the data and the objectives of the data analysis efforts.
The nature of the data:
- Is it qualitative or is it quantitative?
- Is it static or dynamic?
- Is it primary data or secondary data?
- Is it structured or is it unstructured?
- Is it hybrid?
Objectives of statistical data analysis:
- Descriptive: To describe relationships, objects, occurrences or phenomenon.
- Exploratory: To understand unknown or partially-known elements in relationships, objects, occurrences or phenomenon.
- Causal: The find out how a change in a variable(s) will affect the relationships, objects, occurrences or phenomenon related to that variable
- Predictive: To predict the end result of defined interactions amongst relationships, objects, occurrences or phenomenon
- Inferential: To apply discoveries in relationships, objects, occurrences or phenomenon to a wider population
The nature of the data together with the objectives of the data analysis exercise will assist in the identification of the most appropriate data analysis methodology.
