What statistic is represented on the Y axis of a Document Rank distribution chart?

The statistic represented on the Y axis of a Document Rank distribution chart is Relevance Rank. This type of chart is typically used to illustrate how documents are scored based on their relevance to a given query or criteria. The Relevance Rank quantifies and ranks the importance or appropriateness of the documents in relation to the search parameters, allowing project managers or analysts to visualize the effectiveness of their data retrieval processes.

In this context, the relevance ranking helps stakeholders understand which documents are most pertinent for review or further action. By plotting this statistic on the Y axis, the chart clearly indicates the ranking scale, making it easier to assess how various documents compare in terms of relevance.

The other options do not convey the same specific contextual information. Document Distribution pertains to the overall spread of documents without focusing on their relevance. Designation refers to classifications which might not directly relate to the ranking of documents based on relevance. Coding Decision relates to the choices made in the process of categorizing documents but does not provide a quantitative measure of their relevance.
