Range:
The spread of measures between the highest and lowest recordings.

Mean:
The calculated average of a set of data.

Standard Deviation:
The amount of variation of measures with respect to the "mean"

Independent Variable:
The only variable that you change in an experiment.

Normal Distribution:

Hypothesis:

Citation:
A reference attributing work to the original author.

Raw Data:
The measures that you observe and record in your experiment.

Conclusion:
Statement that interprets your results relative to your hypothesis.

Correlation:
Related or associated with an observation, but not the cause of the change.

Casual Repetition:
Circumstances or actions that produce a predicted or measurable change.

Error Bars:
Show the inaccuracy of your measures on a graph.

Processed Data:
Data that has been analyzed by calculating the man, standard deviation and graphing.

Dependent Variable:
