Understanding Data and Its Importance

Data consists of individual pieces of information that can range from simple facts, like daily temperatures, to vast collections of data points, such as historical temperature records over a year. Data scientists actively collect these data points to solve various problems, using available online information to create predictions or recommendations. For example, a data scientist might analyze data on millions of job seekers in the U.S. to help employers find the best candidates for specific roles, such as plumbers or electricians. This role requires an understanding of how to gather and utilize data effectively to inform decision-making in different business contexts.
