As Table 1.1 suggests, there are three types of business analytics:
- descriptive analytics – looking at historical data,
- predictive analytics – trying to predict what might happen, and
- prescriptive analytics – focusing on providing different options.
Table 1.2 illustrates the above concepts by providing examples.
In prescriptive analytics the data used by the GPS might feed into another program, which calculates several alternatives regarding the route and time one should leave the office in the evening to get home the quickest (between 16:00 and 17:00 versus 18:00 and 18:30).

Inferential statistics – what’s that?
Inferential statistics entail drawing conclusion about a parameter (e.g., industry a client works in) from the sample (e.g., of clients) to the population (all clients). However, the sample must be representative of the population for acurracy.
If our data are normally distributed, parametric statistics might be used but if the variables used are not normally distributed, non-parametric statistics must be used.
Below we define these approaches.

Of course, good practice or best practice is an important criteria that we need to address when deciding what type of analyses we want to use. Nevertheless, to understand the subtle differences it is necessary to present some examples illustrating descriptive, predictive and prescriptive analytics.
We can describe descriptive analysis as trying to find out how much time it took us on average (mean) to commute home during last month (see first example in Table 1.2). To illustrate how to apply the predictive analytics framework, we may use our on-board GPS. It might be able to tell us which route to take when getting ready to leave the office to drive home (just imagine gridlocked traffic during rush hour in Los Angeles).

Conclusion
The best way to get things going is to review the existing or as-is state. Successful business analysis regarding social media activities or social sharing requires the formalization of a common vision, a tuned methodology, and a common set of tools that help reduce risks, control costs, and improve performance.
The next step after the above inventory is to build a vision about how business analysis could work when doing social media marketing. For this purpose we have presented the business analysis framework and what methodology would be used.
Tables 1.1 and 1.2 show that business analysis approaches are driven by different challenges that await solutions. As the follow-up presentations will show (e.g., Raise your hand if you hate statistics), when the wrong type of data is collected or inappropriate statistical tools are used, the best methodology does not provide you with the insight you need to make the right decisions.
