What is Data Exploration?
Data exploration is like searching for oil—figuring out where to drill is a combination of art and science, and making the right choices can bring in a gusher. In both cases, exploration is about searching for something when you don’t know where it is. Using the best tools for data exploration enables analysts, IT professionals and business executives to draw substantive insights and quickly identify which data to analyze further.
Let’s take a more in-depth look at data exploration, why it’s important, and how Trifacta can help business users, data analysts and technical users do data exploration faster and more efficiently than ever before.
Why Data Exploration?
Before deeper analysis can be done, you must summarize the characteristics of a dataset: number of cases, variables included, missing observations, and any prospective hypotheses the data might support.
When reviewing the data, the analyst hopes to immediately zero in on variables that will lead to valuable insights about their business. If several data points correlate, those may be great candidates for in-depth analysis. By skipping this first exploratory step, the analyst won’t immediately understand the key issues or won’t be able to guide the deeper analysis in the right direction.
Data Exploration: Using Visual Tools
Historically, analysts have used statistical software for data exploration, but now most use data visualization software and tools. Visualizing data through the use of dashboards, graphs and charts, analysts are better able to quickly discover the most relevant aspects of their datasets.
The best tools don’t just help visualize data, they interact with their analyst as they perform data exploration. Instead of just spitting out limited reports, the best data exploration tools now interact with the analyst and their team, allowing everyone to collaboratively annotate and search datasets, make recommendations for visualizations, and even automate the exploration process through machine-learning.
