What type of statistics are summaries collected by large organizations that are not conducted by scientific researchers called?

The term that refers to summaries collected by large organizations that are not conducted by scientific researchers is indeed "existing statistics." These statistics are compiled from previously collected data often used for various analyses and decision-making purposes, and they serve as a resource for researchers and policymakers.

Existing statistics are valuable because they provide access to a wealth of data that may be costly or impractical to gather anew. They can include data from government reports, financial records, and various non-profit organization databases. By leveraging existing statistics, researchers can analyze trends, patterns, and relationships within datasets without the need for primary data collection.

In contrast, inferential statistics are used to make predictions or inferences about a population based on a sample, while secondary data refers more broadly to data that has been collected by someone else, including existing statistics but not limited to them. Descriptive statistics, on the other hand, summarize and describe the characteristics of a dataset but do not imply any external meaning or application related to the primary usage of existing data.

Understanding these distinctions helps to clarify why existing statistics is the most appropriate terminology for the summaries collected by large organizations.
