Question

Describe data, information, and knowledge in the context of population health.

Answer 1

Ans)Data is measured, collected and reported, and analyzed, whereupon it can be visualized using graphs, images or other analysis tools. Data as a general concept refers to the fact that some existing information or knowledge is represented or coded in some form suitable for better usage or processing.

- Electronic health records, commonly referred to as EHR, provide data to population health professionals that offers direct insight into clinical findings.

- When data are processed, interpreted, organized, structured or presented so as to make them meaningful or useful, they are called information. Information provides context for data.

- Knowledge refers to the awareness or understanding on the subject acquired from education or experience of a person. Information is nothing but the refined form of data, which is helpful to understand the meaning. On the other hand, knowledge is the relevant and objective information that helps in drawing conclusions.
