Science flash cards #1

Intro to science

Independent Variable

The variable you purposely change in your experiment

Dependent Variable

The variable you measure in your experiment

Control Variable

The variable that you keep the same in your experiment to ensure a fair test

Correlation

The relationship between the variables

Evaluation

Looking back at your experiment results the identifying the errors

Fair test

A test where only the independent variable can affect the dependent variable

Hypothesis

An idea which you have that explains certain facts you can test

Validity

The suitability of the experiment to test your hypothesis

Reliable

Data that can be repeated many times, resulting with the same answers

Prediction

A statement where you write what you think might happen in your experiment

Quantitive data

Data that can be recorded in numbers and values

Qualitative data

Data that is recorded in words

Discrete data

Data that can only be recorded in certain whole numbers or values

Continuous data

Data that can be recorded in any value and is not restricted to specific values.

Experiment

An investigation which will provide evidence for or against your hypothesis

Line of best fit

A straight or curved line on a scatter grap, showing the correlation between two variables; roughly passing through the middle of the data points.

Anomalous results

Data points that are out of the expected range, pointed out with a circle

Conclusion

A summary of what you learned from your experiment
