|
Define valid and reproducibility. |
Valid - suitability of the investigative procedure to answer the question being asked. Reproducibility - different people can carry out the same experiment and get similar results. |
|
|
Define observation, prediction, conclusion. |
Observation - information collected in an experiment. Prediction - what you think will happen in an experiment. Conclusion- what the result of an experiment shows. |
|
|
Why is a sample size important when collecting data? |
Increases validity. |
