Final answer:
A control may not produce the expected results due to limitations of the measuring device, the skill level of the person making the measurement, and irregularities in the object being measured. Factors affecting outcomes can also greatly vary with the situation. 2) It is not secure and violates privacy regulations is correct answer.
Step-by-step explanation:
Three reasons why a control may not produce the expected results include:
- Limitations of the measuring device - where the equipment used may not be sensitive or accurate enough to detect or measure the variable accurately.
- The skill of the person making the measurement - this includes both the technical proficiency in using the measuring tools and the ability to interpret the results correctly.
- Irregularities in the object being measured - which can introduce inconsistencies if the object itself is not uniform or has properties that influence the measurement outcome.
Moreover, factors that affect the outcome can be highly dependent on the situation, such as environmental conditions, temporal factors, or unintended interactions within the experimental setup.
