Comparing Data Sets Practice Test

A pharmacology lab monitored a drug in blood plasma. Table A lists measured concentration (mg/L) at several times after dosing. Table B lists percent of the initial concentration at the same times, calculated as $100\times C_t/C_0$. Compare what Table B changes relative to Table A.

A physics lab investigated motion down an incline. Table A shows measured position versus time from video tracking. Table B shows calculated velocity versus time computed from the position data using $

v=\Delta x/\Delta t$. Determine the best description of the relationship.
