Objectives


Visual analytics is a form of analytics in which interactive graphical

displays of data are used to generate analytical results and insights

It integrates new computational and theory based tools with innovative

interactive techniques to enable human-information discourse

Visual representations translate data into a visible form that highlights

important features, including commonalities and anomalies

What is Visual Analytics?


Data visualization refers to the techniques used to communicate data or information by encoding it as visual objects

A primary goal of data visualization is to communicate information clearly and efficiently to users via the Information

graphics selected, such as tables and charts

Data presentation architecture (DPA) is a skill-set that seeks to identify, locate, manipulate, format and present data

in such a way as to optimally communicate meaning and proffer knowledge

Data Visualization


A new generation of business intelligence software puts data into the hands of the people who need it

Slow, rigid systems are no longer good enough for business users or the IT teams that support them

Tableau Software was founded on the idea that data analysis and subsequent reports should not be isolated

activities but should be integrated into a single visual analysis process

Tableau combines data exploration and data visualization in an easy-to-use application that anyone can learn

quickly

IT teams can manage data and metadata centrally, control permissions and scale up to enterprise- wide

deployments

Tableau


The new connector in Tableau 9.x brings native support for a number of statistical package files including:

• .sas7bdat – the file format used by SAS

• .sav – the binary file format used by SPSS

• .rdata, .rda – the file formats employed by the R statistical analysis package

Splitting Data Columns

If you have string fields in your data that contain multiple units of information, it might be easier to analyze the data if you split the values in that field into separate fields.

For example, the first and last name of a customer

You can use split or custom split options in Tableau to separate the values based on a separator or a repeated pattern of values present in each row of the field.

Just right-click on the dimension you want to split, navigate to the new ‘Transform’ menu and click Split.

Tableau will automatically try to figure out the delimiter and split the data accordingly, but you can also choose Custom Split and specify the delimiter yourself if you like.

Data Interpretation

Tableau 9.0 is built in with Data Interpretation option. What is Data Interpretation.

Data Interpretation:

Data Interpretation is the process of making sense of numerical Data that has been collected, analyzed and

Presented.

Let’s check how to use Data Interpretation in Tableau.


Data Interpretation

Point 1 is showing some message that Tableau going to tell us. “Data doesn’t look right? Tableau Data Interpretermight be able to help”.

Why our data is not looking right? Let’s check Point 2, Some rows are showing data as null. Does it add anysense if we import a improper data.

Very difficult to check the data one by one step by step. So Tableau tells us data is not right, if there is anyimproper data.


Data Interpretation

Click on Turn on Button.

Below screenshot shows data after Data Interpreter is on. I want to know the changes what Data Interpreter hasdone to my data.

For that please click on Review results button.


Data Interpretation

By clicking on the Review Results button. We will be redirected to an Excel Sheet.

In key points Tableau clearly mentioned what Data Interpreter has done to our data.

Check the screenshot in next slide, Now all the data is arranged same as the data present in our source data.


Data Interpretation
