What are attributes in data mining?
A person’s hair colour, air humidity etc. An attribute set defines an object. The object is also referred to as a record of the instances or entity. In data mining, understanding the different types of attributes or data types is essential as it helps to determine the appropriate data analysis techniques to use.
What is data mining?
When we talk about data mining, we usually discuss knowledge discovery from data. To get to know about the data it is necessary to discuss data objects, data attributes, and types of data attributes. Mining data includes knowing about data, finding relations between data. And for this, we need to discuss data objects and attributes.
Why is data mining a misnomer?
The term “data mining” is actually a misnomer because the goal is not to extract the data itself, but rather meaningful information from the data . Be assured that you'll submit flawless writing.

What is the difference between data mining and machine learning?
Data mining and machine learning are unique processes that are often considered synonymous. However, while they are both useful for detecting patterns in large data sets, they operate very differently. Data mining is the process of finding patterns in data.
Type of Attributes
This is the First step of Data-preprocessing. We differentiate between different types of attributes and then preprocess the data. So here is the description of attribute types. 1. Qualitative (Nominal (N), Ordinal (O), Binary(B)). 2. Quantitative (Numeric, Discrete, Continuous) geeksforgeeks.org
Qualitative Attributes
1. Nominal Attributes – related to names: The values of a Nominal attribute are names of things, some kind of symbols. Values of Nominal attributes represents some category or state and that’s why nominal attribute also referred as categorical attributes and there is no order (rank, position) among values of the nominal attribute. Example : 2. Bina
Quantitative Attributes
1. Numeric: A numeric attribute is quantitative because, it is a measurable quantity, represented in integer or real values. Numerical attributes are of 2 types, interval, and ratio. 1. An interval-scaledattribute has values, whose differences are interpretable, but the numerical attributes do not have the correct reference point, or we can call ze
