Add Your Comment HereA dashboard to select high-quality stocks with high yield and low volatility
Selecting a "safe" stock with a solid dividend is quite popular in the current economic climate. The traditional "safe" investments are paying extremely low interest rates while many American companies are growing revenues while paying out strong dividend yields (4% and higher) that exceed those of government bonds. In late December, I selected a set of stocks with solid financial strength ratings, positive revenue growth in the past year, dividends of 4% or more and lower than average stock price volatility (also called the beta of a stock.)
After some data cleanup, I assembled this into a dashboard for quick review and exploration. This dashboard allows you to select higher yields, higher revenue growth or lower levels of volatility. By clicking on an individual stock, you are taken to MSN Money web site (below initial dashboard) for their current "StockScouter" rating.

Add Your Comment HereWhy choose Complete Tableau Training by Freakalytics? A recent attendee’s perspective
This review of our 4 day training series was written on LinkedIn by a recent public training attendee, Danyelle. She works at the US Department of Health and Human Services as a Senior Data Advisor. I had the great pleasure of speaking with her outside of the class and was fascinated to hear how she is a change agent for her organization's use of data. They are undergoing significant changes in how their studies are analyzed, presented and shared- all with the goal of increasing the return on their investment in research. You can read her original post in the Tableau Software Group on LinkedIn, it was written in response to our upcoming training in Frankfurt.
"I went to Stephen and Eileen's 4-day Complete Tableau Training in Washington DC a couple weeks ago and it was WELL worth the time and money.
I was most impressed by their case study approach to teaching Tableau. The class ranges from people using Tableau every day at work to people like me who had only read about Tableau.
Reflecting back on the class, I am even more impressed by the quality of instruction and how well it worked for all in attendance. I was immediately able to go back to work and apply the skills I gained in the training to solve a problem that some thought couldn't be done in-house."
Thanks Danyelle for sharing your thoughts! Read all about our training at http://www.Freakalytics.com/training.
Quick tutorial on reference lines, bands and distributions – enhance your graph insights!
The following article features Tableau 6 
Reference lines, bands or distributions may be added to your views to emphasize particular values or areas that may be useful in interpreting your data. In particular, when comparing multiple groups or categories of data, reference lines and bands provide immediate feedback on the overall differences between the groups.
Reference lines
Reference lines are vertical or horizontal lines displayed on your view that mark requested values such as average, median, minimum, maximum, sum, total and constants (such as a line that separates the data points as being above or below a target). They can be added on any continuous axis.
1) Open the Sample - Coffee Chain (Access) data source included by default with Tableau 6

Tableau 6 – how it can change your world
The following article features Tableau 6
Whether you are exploring your data for new insights, answering specific questions or even deciding what questions to ask, Tableau gives you unprecedented control to investigate, communicate and take action with the valuable information hidden in your data! Tableau has it all - a wide variety of options to graph your data, the ability to adjust your data so that you are using the right data in the right form for the questions at hand, and a user-friendly interface that’s designed around how people think about analysis, allowing you to follow your thoughts as you question and explore your data. You can work with every major data source, from Excel workbooks to the largest databases. You can even extract data from larger sources into a local “extract” file that will make your data exploration more efficient and allow offline analysis when you are away from the office.
