Which step in the data mining process is the most important and why

Answer 1

Visualization is the most useful and important technique which is used to discover data patterns. This technique is used at the beginning of the Data Mining process. Many researches are going on these days to produce interesting projection of databases, which is called Projection Pursuit. There are a lot of data mining technique which will produce useful patterns for good data. But visualization is a technique which converts Poor data into good data letting different kinds of Data Mining methods to be used in discovering hidden patterns.

Data Visualization is nothing but the process of presenting information through visual rendering. From centuries back, people have used to visualizations such as charts and maps to understand the information more quickly and easily. As far as human brain is concerned it recognizes the visual data more quickly than the text data.

As more data is collected and analyzed, this data visualization system is welcomed by most of the decision makers. Data visualization helps the decision makers to find out the relevance among the millions of variables, communicate concepts and hypothesis. This also lets them to decide about the future.

Importance of Data Visualization

Technological developments in the current scenario has made Data Visualization more powerful, thus in turn it improves the business intelligence. There are a lot of reasons why businesses use Data visualization. A few are listed down here-

- Visualization helps people to understand things clearly and have a better insight into the topic

- Visualization helps to predict future easily and take better decisions

- Data of large volumes can also be spotted easily and quickly

- Data visualization conveys the information in a universal manner

- It makes it simple to share ideas with others

- Data visualization lets people to know where they need to do an adjustment in their business to get better result

- It provides scalability

- It makes interpretation easy

Why is data visualization important?- Because of the way the human brain processes information, using charts or graphs to visualize large amounts of complex data is easier than poring over spreadsheets or reports. Data visualization is a quick, easy way to convey concepts in a universal manner – and we can experiment with different scenarios by making slight adjustments.

Data visualization can also-

- Identify areas that need attention or improvement.

- Clarify which factors influence customer behavior.

- Help you understand which products to place where.

- Predict sales volumes.
