Assumptions
A team of scientists is studying how the conductivity of a specific metal alloy varies with changes in temperature. Due to budget constraints, they have sourced the alloy from a local recycling facility that specializes in refining metals. The experiments are being conducted in a controlled environment where all other factors – such as room pressure, room volume, and electrical conditions – remain unchanged. Only the temperature will be adjusted.
Which of the following assumptions is essential for the validity of the study?
