The mean is calculated by summing all the values and dividing by the number of values. The median is the middle value when the data is arranged in ascending or descending order. The mode is the value that appears most frequently in the data. These measures provide important information about the typical or representative value in a dataset.

It is the result of raw data being transformed into a more structured and understandable format. Unlike raw data, which is unprocessed and lacks context, processed data has undergone some form of data processing to extract relevant insights or conclusions. Therefore, processed data accurately describes the term "information" as it represents data that has been processed and made meaningful.

    Noise in information retrieval is due to...

    • A.

      Raw Information

    • B.

      Recalling Information

    C. Redundant Information
    Explanation
    Noise in information retrieval refers to any irrelevant or unnecessary information that can interfere with the retrieval process. Redundant information, which is the correct answer, is a common source of noise. It refers to the repetition or duplication of data or content that does not provide any additional value or meaning. Redundant information can make it difficult for users to find the relevant information they are looking for, as it adds clutter and confusion to the retrieval process. Therefore, eliminating or minimizing redundant information is essential for improving the efficiency and accuracy of information retrieval systems.

    D. Folksonomy
    Explanation

Unlike traditional taxonomies or directories, which are created by experts, folksonomies rely on the collective wisdom of users to assign relevant tags to content. This allows for a more dynamic and flexible way of organizing information, as it reflects the diverse perspectives and interests of the users.

    A table is not a graphic illustration of information, but rather a textual representation of data organized in rows and columns. It does not use visual elements such as bars, lines, or slices to represent data like the other options (histogram, pie chart, and bar chart) do. Instead, a table presents data in a structured format, making it easier to compare and analyze values in a tabular form.
