Exam 8: Causal Research Design: Experimentation

As compared to the field, experimentation in social media offers the advantages of ease of implementation and lower cost.

Designs that apply part of the procedures of true experimentation, while lacking full experimental control are called ________.

Designs that apply part of the procedures of true experimentation, while lacking full experimental control are called quasi-experimental designs.

The internal and external validity of field experiments conducted overseas is generally higher than in the United States.

Explain the concept of causality as defined in marketing research and distinguish between the ordinary meaning and the scientific meaning of causality.

The static group is a two-group experimental design in which one of the groups acts as a control group, the subjects are not assigned randomly, and measurement are made on both groups following the treatment.

Using the set of symbols commonly used in marketing research to denote experimental designs, which symbol below represents the exposure of a group to an independent variable, treatment, or event the effects of which are to be determined?

According to the text, experiments can be described in terms of interdependent variables.

________ refers to an extraneous variable attributable to changes in the test units themselves that occur with the passage of time.

A(n) ________ is a statistical experimental design used to measure the effects of two or more independent variables at various levels and to allow for interactions between variables.

An experimental design in which the test units are assigned randomly and the experimental group is exposed to the treatment but the control group is not and no pretest measure is taken is called the ________.

Concomitant ________ occurs when the presumed cause and presumed effect are both present and both vary in a manner predicted by the researcher's hypothesis.

The control group is not exposed to the independent variable manipulation, but provides a point of comparison when examining the effects of these manipulations on the dependent variable.

Which of the following can be symbolized as: EG: R X O1 CG: R O2 Where, X = the exposure of a group to an independent variable, treatment, event, the effects of which are to be determined O = the process of observation or measurement of the dependent variable on the test units or group of units R = the random assignment of test units or groups to separate treatments CG = control group EG = experimental group

The ________ is a preexperimental design in which a group of test units is measured before and after exposure to the treatment.

Individuals, organizations, or other entities whose response to independent variables or treatments is being studied are called test units.

________ refers to whether the cause-and-effect relationships found in the experiment remain the same when replicated in a larger population.

Causality refers to when the occurrence of X causes the occurrence of Y.

The ________ is a quasi-experimental design that involves periodic measurements on the dependent variable for the group of test units.

The process of manipulating one or more independent variables and measuring their effect on one or more dependent variables while controlling for the extraneous variables is called a(n) ________.
