Question

Quizplus · Accepted Answer

A data matrix is a table consisting of rows and columns that organizes data in a format where the rows represent respondents or cases, and the columns represent variables or attributes. The data is usually coded and can be in the form of numerical or categorical data. Therefore, coded raw data arranged in columns representing answers to various questions and in rows representing each respondent or case best describes a data matrix. Choices A, B, and C are components of creating a data matrix but do not fully describe what a data matrix is. Choice E describes a diagonal matrix, which is a specific type of matrix arrangement where the values on the diagonal are of particular interest.
