Back

What the expected outcome will be and how it will be measured.

Front

Back

In a controlled experiment, one group serves as the 'standard' and data from the experimental groups is compared against the 'standard' to see if there is a change.

Front

Back

Independent variable

Dependent variable

Front

What is a possible research question, that created this graph?

Back

Does the temperature outside affect the number of chirps a cricket chirps?

Front

What is the Independent variable?

Back

It's on the x axis: Temperature (oF)

Front

The hypothesis for this experiment:

The temperature in the room has no affect on the number of chirps a cricket chirps.

Does the data support or refute the hypothesis?

Back

According to the data as the temperature increases the number of chirps per minute also increases, thus our hypothesis is not supported.
