Exam 7: Casual Research Design: Experimentation

Full experimental control is available in quasi-experimental designs;therefore,the researcher does not need to take into account the specific variables that are not controlled.

Which of the following is true of the one-shot case study preexperimental design (X O1)?

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

Evidence of concomitant variation,time order of occurrence of variables,and elimination of other possible causal factors,when combined,demonstrate conclusively that a causal relationship exists.

The one-group pretest-posttest design may be symbolized as O1 X2 O2.In this design,a group of test units is measured ________.

Which statement is not true concerning a standard test market?

Which of the following statements is an advantage of statistical designs?

________ is the extent to which a cause,X,and an effect,Y,occur together or vary together in the way predicted by the hypothesis under consideration.

All of the types of experimental designs mentioned in the chapter on Causal Research Design (Latin Square,factorial,true experimental,and preexperimental designs for example)can be implemented on the Internet.

Price levels,package designs,and advertising themes are examples of independent variables manipulated by the researcher.

Evidence pertaining to concomitant variation can only be obtained in a qualitative manner.

________ is a determination of whether the cause-and-effect relationships found in the experiment can be generalized.Can the results be generalized beyond the experimental situation and if so,to what populations,settings,times,independent variables and dependent variables can the results be projected?

Using the set of symbols commonly used in marketing research to denote experimental designs,which symbol below represents the process of observation or measurement of the dependent variable on the test units or group of units?

A ________ is a test marketing program conducted by an outside research company in field experimentation.The research company guarantees distribution of the product in retail outlets that represent a pre-determined percentage of the market.

A ________ design to measure the effectiveness of a test commercial for Sears would be implemented as follows.Respondents are recruited to central theater locations in different test cities.At the central location,respondents are first administered a personal interview to measure,among other things,attitudes toward the store (O1).Then they watch a TV program,the respondents are again administered a personal interview to measure attitudes towards the store (O2).The effectiveness of the test commercial is measured as O2 - O1.

Which of the following statements is not true concerning the time order of occurrence of variables?

The static group is a two-group experimental design.One group,called the ________,is exposed to the treatment,and the other,called the ________,is not.Measurements on both groups are made only after the treatment,and test units are not assigned at random.

The conditions of concomitant variation,time order of occurrence of variables and elimination of other possible causal factors,are necessary but not sufficient to demonstrate causality.

Debriefing occurs after the experiment and entails informing test subjects what the experiment was about and how the experimental manipulations were performed

There is no problem developing experimental designs that have high levels of both internal and external validity.
