20 General Advice About Blocking —When in doubt, block —Block out the nuisance variables you know about, randomize as much as possible and rely on randomization to help balance out unknown nuisance effects —Measure the nuisance factors you know about but can’t control —It may be a good idea to conduct the experiment in blocks even if there isn't an obvious nuisance factor, just to

2009 The McGraw-Hill Companies, Inc. 1. Outcomes of a 2 x 2 Factorial Design Notation. Fractional designs are expressed using the notation l k − p, where l is the number of levels of each factor investigated, k is the number of factors investigated, and p describes the size of the fraction of the full factorial used.

IV X PV design One common type of factorial design that includes both experimental (manipulated) and nonexperimental (measured or nonmanipulated) variables. For Example: Independent Variable by Participant Variable) - allows researchers to investigate how different types of Individuals / Participants respond to the same manipulated variables.

Main effect The direct effect of an independent variable on a dependent variable. IV x PV designs type of factorial design that includes both experimental (manipulated) and non experimental (measured or non manipulated) variables; independent variable by participant variable what does the IV x PV design allow researchers to do?

You can display more than one stratification variable at a time by clicking on multiple variable names in the X Axis list box.

In the fish farm example, imagine adding another factor, temperature, with four levels into the mix. It would then be 4 x 4 x 4, or 64 runs.

This would be called a 2 x 2 (two-by-two) factorial design because there are two independent variables, each of which has two levels. If the first independent variable had three levels (not smiling, closed-mouth, smile, open-mouth smile), then it would be a 3 x 2 factorial design.

Describe a specific situation for which each of the following experimental designs is appropriate.

IV x PV designs Used when one variable is manipulated by the researcher and the other variable is a participant or grouping variable. Assess: Main effect of manipulated independent variable Main effect of participant variable Interaction of IV and PV.
