An independent variable...

is what you intentionally change in your experiment

a part of an experiment that does not change

Why is it important to have a control group?

So you know the effect of the independent variable

Which statement is an inference?

My foot hurts, so it must be broken.

What can you conclude from the graph below?

Soccer is the student's favorite sport

Temperature was measured before students entered the class and then after.We can conclude that

Body heat from the students causes temperature to rise.

an explanation based on what you observe and already know
