Defining Data
Introduction
Data are facts, information, observations and measurements that are used to make discoveries and to support informed decisions. A dataset, which is a collection of data may come in different formats and structures, and will usually be based on its source, ot where the data came from. For example, a company's monthly earnings might be in a spreadsheet but hourly heart rate data from a smartwatch may be in JSON format. It's common for data scientists to work with different types of data within a dataset.
This lesson focuses on identifying and classifying data by its characteristics and its sources.
