You can create a dummy treatment in Minitab by repeating levels for a factor if there are at least two different levels. For example, if you want to use an L9 (3 4) array, which has four three-level factors, but you have one factor with only two levels, you can use a dummy treatment. Factor A has repeated level 1, instead of level 3.
What is a dummy pill placebo?

What are the advantages of a dummy-coded variable?
Another advantage of a 0,1 dummy-coded variable is that even though it is a nominal-level variable you can treat it statistically like an interval-level variable (if this made no sense to you, you probably should refresh your memory on levels of measurement ).
What is the name for a dummy treatment?
A placebo (or dummy pill) is an inert (inactive) substance, typically a tablet, capsule or other dose form that does not contain an active drug ingredient. For example, placebo pills or liquids may contain starch, sugar, or saline.

dummy (n.) 1590s, "mute person," from dumb (adj.) + -y (3). Extended by 1845 to "figure representing a person," hence "counterfeit object, something that imitates a reality for mechanical purposes." In card games (originally whist, later bridge) "exposed hand of cards placed face-up," by 1736.
What happens in the brain during placebo effect?
Placebo effects are thus brain–body responses to context information that promote health and well-being. When brain responses to context information instead promote pain, distress and disease, they are termed nocebo effects .
What part of the brain is responsible for placebo?
Multiple studies have singled out the ventromedial prefrontal cortex (vmPFC) as a main player in mediating the placebo effect.
How do placebos change the patient's brain?
Large placebo responses were associated with greater dopamine and opioid activity in the nucleus accumbens. Conversely, pain increase-related nocebo responses were associated with a deactivation of dopamine and opioids.

When choosing a factor level to use as a dummy treatment, what should you consider?
When you choose which factor level to use as the dummy treatment, consider the amount of information about the factor level and the availability of experimental resources. For example, if you know more about level 1 than level 2, you may want to choose level 2 as your dummy treatment. Similarly, if level 2 is more expensive than level 1, ...

What is a dummy variable?
A dummy variable is a numerical variable used in regression analysis to represent subgroups of the sample in your study. In research design, a dummy variable is often used to distinguish different treatment groups. In the simplest case, we would use a 0,1 dummy variable where a person is given a value of 0 if they are in the control group or a 1 if they are in the treated group. Dummy variables are useful because they enable us to use a single regression equation to represent multiple groups. This means that we don’t need to write out separate equation models for each subgroup. The dummy variables act like ‘switches’ that turn various parameters on and off in an equation. Another advantage of a 0,1 dummy-coded variable is that even though it is a nominal-level variable you can treat it statistically like an interval-level variable (if this made no sense to you, you probably should refresh your memory on levels of measurement ). For instance, if you take an average of a 0,1 variable, the result is the proportion of 1 s in the distribution.
