Independent, Dependent, and Constants Quiz

Which variable is manipulated or changed by the experimenter?

• dependent variable

• control variable

• confounding variable

• independent variable

What is the variable that is measured or observed in an experiment?

• independent variable

• control variable

• dependent variable

• confounding variable

In an experiment, what remains the same and does not change?

• Independent variables

• Dependent variables

• Control variables

• Experimental group

Which variable is plotted on the x-axis of a graph?

• control variable

• y-axis variable

• dependent variable

• independent variable

Which variable is plotted on the y-axis of a graph?

• x-axis variable

• dependent variable

• control variable

• independent variable

What is the purpose of constants in an experiment?

• To control the dependent variable and manipulate the results.

• To introduce variability and uncertainty into the experiment.

• To make the experiment more complicated and challenging.

• To ensure that only the independent variable is changing and any observed effects can be attributed to the independent variable alone.

In a study investigating the effect of temperature on plant growth, what is the independent variable?

• light intensity

• soil pH

• water availability

• temperature

In a study investigating the effect of temperature on plant growth, what is the dependent variable?

• temperature

• plant growth

• soil pH

• amount of sunlight

In a study investigating the effect of temperature on plant growth, what could be a constant?

• type of plant

• type of soil

• amount of sunlight

• amount of water

Why is it crucial to maintain constant conditions in an experiment?

• To make the experiment more challenging.

• To ensure the validity of the experiment's results.

• To enhance the complexity of the experiment.

• To make the experiment more entertaining.
