Question

Quizplus · Accepted Answer

Data input is not a major cause of variance as long as the data is inputted correctly and consistently. Tinkering variance occurs when people change a process without understanding its effects, systematic change occurs when a change in the system or process affects the outcomes, external causes are factors outside of the system or process that influence the outcomes, and random variance occurs due to natural variations in the system or process.
