== Create Experiment Design ==
=== Description ===
Laboratory Experiment:

Independent variables are manipulated by the researcher (as treatments).
Subjects are randomly assigned to treatment.
Results of the treatments are observed.
Suited for explanatory research to examine individual cause-effect relationships in detail.
Strengths:

Influence of individual factors can be well explained.
very high internal validity (causality)

Field Experiment:

Conducted in field settings, e.g. real organization.
Rare, because of the difficulties associated with manipulating treatments and controlling for extraneous effects in a field setting.
Strengths:

high internal and external validity

=== Examples ===
Provide some examples for the activity X.

=== Further Readings ===
Provide further readings for activity X.

== Develop/Design Treatments ==
=== Description ===
Treatment and control groups:
* In experimental research, some subjects are administered one or more experimental stimulus called a treatment (the treatment group) while other subjects are not given such a stimulus (the control group).
* Independent variables are manipulated in one or more levels (called “treatments”).
* Effects of the treatments are compared against a control group where subjects do not receive the treatment.
* The treatment may be considered successful if subjects in the treatment group rate more favorably on outcome variables than control group subjects.
* Multiple levels of experimental stimulus may be administered, in which case, there may be more than one treatment group.
* Treatments are implemented in experimental or quasi-experimental designs but not in nonexperimental designs.
* Treatment manipulation helps control for the “cause” in cause-effect relationships.

=== Examples ===
Multiple treatment groups:

For example, in order to test the effects of a new drug intended to treat a certain medical condition like dementia, if a sample of dementia patients is randomly divided into three groups, with the first group receiving a high dosage of the drug, the second group receiving a low dosage, and the third group receives a placebo such as a sugar pill (control group), then the first two groups are experimental groups and the third group is a control group. After administering the drug for a period of time, if the condition of the experimental group subjects improved significantly more than the control group subjects, we can say that the drug is effective. We can also compare the conditions of the high and low dosage experimental groups to determine if the high dose is more effective than the low dose.

=== Description ===
[[File:Perform Experimental Data Analysis.png|thumb]]
Internal validity = causality

Does a change in the independent variable X really cause a change in the dependant variable Y?
causality <> correlation!

External validity = generalizability

Can the observed association be generalized from the sample to the population or further contexts? [1, 2]
