Is data mining technique equally applicable?
technique is equally applicable to all the tasks. The choice of a particular combination of data mining techniques to apply in a particular situation depends on both the nature of the data mining. task to be accomplished and the nature of the available data.
Can data mining learn from statistics?
As seen, answering “yes” to the latter would be absurd. Rather, it is important to note that data mining can learn from statistics . – that, to a large extent, statistics is fundamental to what data mining is really trying to achieve. There is the opportunity for an immensely rewarding synergy between data miners and.
What is Data Mining?
Data mining, or knowledge discovery from data (KDD), is the process of uncovering trends, common themes or patterns in “big data”. Uncovering patterns in data isn’t anything new — it’s been around for decades, in various guises. The term “Data Mining” appeared in academic journals as early as 1970 (e.g. Jorgenson et. al, 1970). But it only really migrated into popular use in the 1990s, after the advent of the internet.

Make a Histogram: If you have a very large set of data, a histogram can reduce your data to a simple set of bins; Bins work like sorting bins in real life — imagine physically sorting the data into a set of 20 bins.
What is clustering in data?
A cluster is a group that has some characteristic in common. If your data isn’t class-labeled, clustering can uncover associations in the data. Clusters (groups) are formed so that the data items have the maximum amount in common with each other, and as little in common as possible with data items in other clusters. 3.
What is data set?
Data sets are collections of data. Any set of items can be considered a data set. For example {1,2,3} is a data set consisting of three items. On the opposite end of the scale, sets can contain millions of items, like the data from the US Census. Each single value in a data set (like 1, 2 or 3 in the above set) is called a datum.
Abstract
Data mining (DM) is the exploration and analysis of large quantities of data in order to discover meaningful patterns and rules. It allows users to analyze data from many different dimensions or angles, categorize it, and summarize the relationships identified into useful information.
