Dataset
A dataset is a structured collection of data, typically organized in tabular format, that is used for analysis, modeling, or research purposes in various fields such as machine learning, statistics, and data science. A dataset consists of individual data points or observations, each representing a specific entity or event, and is composed of one or more attributes or features that describe these entities.
Key characteristics of datasets include:
Data Points or Observations:
Attributes or Features:
Tabular Format:
Variables and Values:
Metadata:
Datasets play a crucial role in various data-driven tasks, including exploratory data analysis, statistical inference, model training and evaluation, and hypothesis testing. They serve as the foundation for building predictive models, uncovering patterns and insights, and making informed decisions based on data-driven evidence.
Datasets can vary significantly in size, complexity, and domain, ranging from small, well-curated datasets used for academic research to large, heterogeneous datasets collected from real-world applications such as social media, healthcare, finance, and environmental monitoring.
