A manufacturing company in Lagos generates the following data daily: production volumes, machine downtime logs, raw material consumption, and employee attendance records. Which classification BEST describes these data in the context of management information systems?

Production volumes, machine downtime logs, raw material consumption, and employee attendance records are all generated from within the organisation, making them internal data. They are expressed in numerical measures (units, hours, quantities), classifying them as quantitative data. External data originates from outside the organisation, which does not apply here.
