Trails are Repeated

More than one trial is planned to measure the responding variable.

Record Measurement

The procedure states or implies that measurements are recorded periodically.

5. Data

The data is presented in an organized table with labeled units.

6. Analysis

The results are described and the hypothesis is evaluated.

A graph may be used to show patterns in the data.

7. Conclusion

Answer

The investigation question is answered.

Supporting Data

At least two data points (high and low) are given.

Explanation

Differences in the data are used to show how the results support the conclusion.
