A short-term Tableau course should be on your itinerary if you want to rise to the corporate ladder. In today’s digital age, almost every industry is sitting on an overwhelming amount of data. After sifting through the free-flowing data and separating relevant info from the noise, you need to present your case in an easy-to-digest manner. Tableau can make your job easier and give you an edge over traditional tools.
Tableau offers an easy-to-understand user interface where you can analyse data. Its advanced dashboard, attractive visual charts, and other features make it the best tool for data visualization.
The best way to learn data visualization in Tableau is by enrolling in a Tableau certification like the one by Edvancer. Before that, you must understand the basics of Tableau, its key features, and its advanced techniques for data analysis & visualization.
What is Tableau?
Tableau is a data visualization tool used in data analytics. It aims to enhance the flow of analysis and make data easy to understand for people by converting it into visuals. Tableau helps you analyse structured and unstructured data sets easily and identify the patterns in them. Apart from creating traditional charts and graphs, you can use Tableau to draw meaningful insights from the data.
Main Features of Tableau
Some key features of Tableau are as follows:- Attractive Visualizations: You can create different types of simple as well as complex visualizations.
- Advanced Dashboard: The advanced dashboard of Tableau allows you to view the data in the form of a story by selecting a format and layout of your choice.
- Security System: Tableau ensures the security of your data with a system based on permissions and authentication mechanisms.
- In-memory and Live Data: Tableau allows you to analyse data from various external sources by ensuring seamless connectivity between data extracted from all sources.
Advanced Tableau Techniques
The following are some best advanced Tableau techniques that make the data analytics process easier and much more efficient:
1. Segmentation and Cohort AnalyticsEvery business needs to understand its target audience very clearly. Segmenting your audience helps you to improve your marketing strategy and pull more earnings for every penny spent. A few of the questions segmentation will answer for you include:
- Who are your customers?
- What do they buy?
- What are their requirements?
- Where do they gather?
Cohort analysis in Tableau helps you with the segmentation. A cohort refers to a group of people having similar characteristics. It allows you to view all the data in one place and categorize it based on different factors using cohort analysis.
Segmentation can also be done using automated clustering, which is an unsupervised machine-learning technique. Tableau allows you to use clustering to segment large data, especially when there are lots of variables.
2. Advanced GraphsApart from the traditional line charts, bar graphs, etc., Tableau allows you to visualize data sets using several advanced graphs:
- Motion Chart: A motion chart uses the x-axis and the y-axis to represent the change in variables over time. The changes are marked by the movement of data points, and variation in the colours of data lines.
- Bump Chart: A bump chart is an advanced form of a line plot. It allows you to explore the ranks of different variables by comparing their positions. In short, it can be used to identify the popularity of products.
- Donut Chart: You can understand a doughnut chart as a pie chart with a hole in between. These charts are used to show the proportions of categorised data.
- Waterfall Chart: A waterfall chart helps you visualise positive and negative growth. You can use them to see changes in measures over the year.
- Pareto Chart: These are a combination of bar and line graphs. The chart presents the values in descending order and determines the most significant problems and risk management.
Tableau also allows you to implement statistical methods, such as Correlation, Skewness, Covariance, Mode, Kurtosis, Standard Deviation, etc. Moreover, you can use statistical models like K-Means, Naive Bayes, Random Forest, etc., to understand data and make predictions.
These features in Tableau help you solve complex calculations with ease. The calculation fields (LOD and table calculations) also allow you to develop new data points from the existing data.
4. Time Series and Predictive AnalysisTime series analysis helps identify seasonal trends, i.e., how certain variables change over time. Tableau provides a simple interface for time series analysis that helps you understand trends and patterns in data. With this, you can understand the data better and make predictions.
5. What-If AnalyticsThe flexible user interface of Tableau has seamless input capabilities. It helps in making calculations and determining different scenarios. You can see how the output gets affected by changing input parameters.
The ‘parameters’ feature allows you to change the initial conditions and helps in scenario analysis. The ‘story points’ feature allows you to define your scenarios.
