Levels of Analytics Maturity

Not all organizations are the same when it comes to data. There are many factors that determine the what/when/how data is collected, analyzed, and presented. However, I think after working with a number of companies over the years, that they fall into four basic levels. For a variety of reasons it can be difficult to move from one level to another.

Graphing With R

There are a number of ways in ggplot to express your data.  The first are the geometric objects:

  • geom_bar(): Bar charts
  • geom_point(): Points – great for scatter plots

  • geom_density(): Smoothed density plot
  • geom_qq(): A quantile-quantile plot
  • geom_errorbar(): Error bars

All of these geoms (and more) are highly customizable.  But first we must set up the data. Continue reading

Something About Data

With this post I am going to briefly walk through some things about data you many not have thought about.   I think that this might give you a different and useful perspective on the nature of data.  I’ll start first with the various types of data and data elements.  Then I’ll get into some data issues and finish up with data classification and standardization.

Types of Data Generally, data falls into one of three types:

  • Quantitative
  • Qualitative
  • Descriptive
