Semester Review 1/5: Graphing and Experimental Design

Front

What is the dependent variable in an experiment?

Back

The dependent variable is the variable that is measured or observed in an experiment, and it changes in response to the independent variable.

Front

What is the independent variable in an experiment?

Back

The independent variable is the variable that is manipulated or changed in an experiment to observe its effect on the dependent variable.

Front

What is a control in an experiment?

Back

A control is a part of the experiment where the independent variable is not present, serving as a baseline for comparison.

Front

What is the y-intercept in a graph?

Back

The y-intercept is the point where the line crosses the y-axis, indicating the value of the dependent variable when the independent variable is zero.

Front

What does it mean when we say 'as time increases, distance increases'?

Back

This indicates a positive correlation between time and distance, meaning that more time spent results in greater distance traveled.

Front

What is the purpose of constants in an experiment?

Back

Constants are factors that remain unchanged throughout the experiment to ensure that the results are due to the independent variable.

Front

How do you identify the dependent variable in a scenario?

Back

Look for the outcome or effect that changes in response to the independent variable.

Front

What is the relationship between independent and dependent variables?

Back

The independent variable is manipulated to observe its effect on the dependent variable.

Front

What is an example of an independent variable?

Back

In an experiment measuring the effect of study time on test scores, the amount of study time is the independent variable.

Back

In an experiment measuring the effect of study time on test scores, the test scores are the dependent variable.
