Creating 3D paper models to visualize data

An inter­est­ing way to grasp data is to hold a model in your hand and expe­ri­ence it in 3D through a paper model. Below is a 3D pie chart visu­al­ize using paper. It was cre­ated by Nick O’ Leary, an engi­neer with IBM in the UK. Nick’s blog is here; he has cre­ated a custom […]

On Partial Classifications & Miscellanies

I am con­tin­u­ing to read on clas­si­fi­ca­tion which is a fas­ci­nat­ing topic. Not all clas­si­fi­ca­tions are enhaus­tive; some depend on a large class of mis­cel­lany, oth­ers are par­tial clas­si­fi­ca­tions and these may work depend­ing on the con­text and list of terms. The scholar Carl Dar­ling Buck wrote A Dic­tio­nary of Selected Syn­onyms in the Principal […]

Classification, ancient musical instruments, and data analysis

Clas­si­fi­ca­tion is a key tech­nique to ana­lyz­ing data that yields very dif­fer­ent results based on the clas­si­fi­ca­tion scheme. One tech­nique is to use two dif­fer­ent clas­si­fi­ca­tion schemes on the same dataset, do the same analy­sis and com­pare the results to find hid­den insights in data. As an exam­ple, in the 17th cen­tury book De Tribus […]

Why your next CMO will come from big data

A recent blog post from Car­los Cata of Hei­drick and Strug­gles claims that 50% of CMO searches he has recently placed need big data or mar­ket­ing ana­lyt­ics exper­tise as a key com­po­nent. Here’s a quote: While orga­ni­za­tions have had sta­tis­ti­cal and ana­lyt­i­cal resources in the past, there is a height­ened need for strate­gic and marketing […]

Finding few best practices that have exponential results

How do you iden­tify best prac­tices which pro­duce expo­nen­tial results? If you are run­ning a mar­ket­ing pro­gram with 100 part­ners, how do you find the tac­tic or tac­tics which pro­duce not just a lin­ear return, but an expo­nen­tial one? Here’s a tech­nique which has worked for me in the past: 1. Look at each of […]

Graphing Accuracy of Forecasts

Graph­ing a series of mul­ti­year fore­casts vs. actu­als can pro­vide insight into fore­cast accu­racy and meth­ods. This graph looks at a series of rev­enue per share pro­jec­tions for Apple Note that none of the fore­casts showed the expo­nen­tial growth, but assumed essen­tially lin­ear growth. (the fore­cast lines are gray and extend for mul­ti­ple years. Actuals […]

[p] Interesting Big Data

As an exper­i­ment, I’ve cre­ated a series of pin boards on Pin­ter­est cov­er­ing Big Data Star­tups Map­ping and Car­tograms Cool visu­als Big Data Ideas Visu­al­iza­tion and Chart­ing Word maps and clouds Big Data Book­shelf At this point, my thoughts are that Pin­ter­est is a great ser­vice to take snap­shots of inter­est­ing things related to big […]

How to use symbols for greater impact in charts

Using sym­bols to rep­re­sent data can increase impact and under­stand­ing of the under­ly­ing data. In this post, I’ll dis­cuss some best prac­tices for doing this suc­cess­fully in charts, maps, and dia­grams. The fol­low­ing weather sym­bols are used to show driz­zle, rain, and snow a. The sym­bols look roughly like driz­zle, rain­drops, and snowflakes: They are […]

Use Metadata to improve reporting portals (2 of 9 Best Practices)

Meta­data is crit­i­cal to to help the user find the reports he or she are look­ing for as it adds addi­tional infor­ma­tion about what’s in the reports. What’s meta­data? Strictly it is “data about data” or addi­tional descrip­tions, tags, fields that describe the data or report. Here’s a sug­ges­tion for small report­ing por­tals: Brief description […]
