Study Notes

Data and Science

Data is considered tainted at birth and belongs either to Chance or to Science, but never both.
Inferential statistical analysis is used to exercise the demon Chance and ensure data belongs to Science.

Experiments

An experiment is a controlled procedure to investigate the effects of one or more independent variables on one or more dependent variables.
Experiments aim to eliminate or minimize extraneous variation and are performed to test theories, replicate and expand previous findings, or contradict prior research.

Independent and Dependent Variables

Independent variables are chosen because they are thought to control behavior, and their manipulation is inadequate if they do not produce the desired effect.
Dependent variables must be stable and consistently produce the same results under the same conditions.

Behavioral Research Designs

Small-N Designs are used when interested in minute details of individual performance or behavioral change, or when few subjects are available.
Mixed Designs combine within-subjects and fully-crossed factorial designs and are used when both quantitative and qualitative data are needed.

Mixed Designs

Mixed Designs originated in agricultural research and were popularized by Campbell and Fiske's work on triangulation in 1959.
Data analysis in Mixed Designs involves combining quantitative and qualitative data.

Control Condition Designs

Control Condition Designs ensure each treatment appears equally often in different positions within the sequence to prevent differential carryover effects.
Complete counterbalancing makes sure all possible treatment orders are used to balance out order effects.

Small-N Designs

Small-N Designs involve one or a few subjects, run individually, with long experiment duration, and data analyzed visually with minimal use of inferential statistics.
Small-N Designs are used in clinical studies, education, and training, and have a long history dating back to Sir Francis Galton's work on correlations and Sir Ronald Fisher's development of ANOVA.
