Data analytics, data can be categorized into various types based on different characteristics. These data types help analysts understand how to handle and analyze the information effectively. The main types of data in data analytics are:
Numerical Data:
Continuous Data: This type of data can take on an infinite number of values within a given range. Examples include height, temperature, and time. (Data Analytics Training in pune)
Discrete Data: Discrete data can only take specific, distinct values. Examples include the number of employees in a company or the number of customer complaints in a month.
Categorical Data (Qualitative Data):
Nominal Data: Nominal data represents categories with no inherent order or ranking. Examples include gender, color, or product categories.
Ordinal Data: Ordinal data represents categories with a specific order or ranking. For example, educational levels (e.g., high school, bachelor's, master's) are ordinal data because they have a clear hierarchy. (Data Analytics classes in pune)
Binary Data:
Binary data is a specific type of categorical data with only two possible values. Examples include yes/no, true/false, or 0/1.
Text Data:
Text data consists of unstructured text, such as customer reviews, tweets, or articles. Natural language processing (NLP) techniques are used to analyze and extract information from text data.
Time Series Data:
Time series data represents data points collected or recorded at successive points in time. Examples include stock prices, temperature readings, and monthly sales figures.
Geospatial Data:
Geospatial data includes information associated with geographic locations. Examples include GPS coordinates, maps, and geographic information system (GIS) data.
Image and Video Data:
Image and video data consist of visual information. Computer vision techniques are used to analyze and process this type of data. Examples include medical images, surveillance footage, and satellite imagery. (Data Analytics course in pune)
Audio Data:
Audio data represents sound recordings, music, or voice recordings. Audio analysis techniques, such as speech recognition or audio classification, are applied to this data.
Multi-dimensional Data (Multivariate Data):
Multi-dimensional data involves multiple variables or attributes for each data point. Analyzing this data often requires advanced techniques like multivariate statistics or machine learning.
Big Data:
Big data refers to extremely large and complex datasets that exceed the capabilities of traditional data processing tools. Big data analytics technologies are used to handle and analyze such data, often leveraging distributed computing and storage systems.
Understanding the type of data you are working with is crucial because it influences the choice of analytical techniques and tools.
Different data types require different preprocessing and analysis methods to extract meaningful insights and make informed decisions in data analytics.
