the independent variable is plotted on the y - axis, and the dependent variable is plotted on the x - axis.
the independent variable is plotted on the x - axis, and the dependent variable is plotted on the y - axis.

which of the follow statements is incorrect concerning the scientific method equipment?
temperature sensors are used to measure temperature of the forehead
blood pressure monitors are used to measure systolic and diastolic blood pressure
timers are used to measure time
balances (scales) are used to measure mass / weight
meter sticks are used to measure length
finger oximeters are used to measure systolic and diastolic blood pressure
rulers are used to measure length

Explanation:

• For the first question: In graphing, the independent variable is the one that is manipulated or controlled, and it is plotted on the x - axis. The dependent variable depends on the independent variable and is plotted on the y - axis.
• For the second question: Finger oximeters are used to measure oxygen saturation in the blood, not systolic and diastolic blood pressure. Blood pressure monitors are for blood pressure.

Answer:

• First question: The independent variable is plotted on the x - axis, and the dependent variable is plotted on the y - axis.
• Second question: Finger Oximeters are used to measure systolic and diastolic blood pressure.
