Should show no response to the experiment.
Negative control
The upper and lower limits of the data set.
Range
Average of the data set, a calculated central value.
Mean
A measure of the dispersion, relates to the precision of the data set.
Standard deviation
how far "off" from the central value, relates to accuracy of the data set.
Standard error of the mean
a final answer of explanation
conclusion
interpretation of the data and projections as to the meaning of the results.
Discussion
An error resulting from the under representation or lack of representation for a particular factor.
Sampling error
State of being correct, nearness to "true" value.
Accuracy
The resolution of the representation, consistency among values.
Precision
Factor that masks the true relationship of the independent and dependent variables.
Confounder
