True or False with these questions. (can fill with "not sure")

1. Marketing research is a must for a marketer to make any marketing decision.

2. The time involved in primary data collection may render the study obsolete

3. In drawing a sample with stratified sampling, the population is divided into internally heterogeneous subgroups

4. The non-response error in face-to-face survey is more prominent than in mal survey.

5. The introduction of a four-day week, leads to increased productivity particularly among young workers by improving job satisfaction "in this statement, improving job satisfaction is the dependent variable"

6. An experience survey is superior to a focus group since it uses experts.

7. In cluster sampling, we randomly choose elements from each subgroup.

8. The two-stage research approach often uncovers evidence that a major study is unnecessary in the first stage.

9. A codebook, or coding scheme, contains each variable in the study and specifies the application of coding rules to the variable.

Expert Solution

Ques-1 False. Marketing research serves marketing management by providing information which is relevant to decision making. Marketing research does not itself make the decisions, nor does it guarantee success. Rather, marketing research helps to reduce the uncertainty surrounding the decisions to be made.

Ques-2 True. The time involved in primary data collection may render the study obsolete.

Ques-3 False. A sample may be selected from a population through a number of ways, one of which is the stratified random sampling method. A stratified random sampling involves dividing the entire population into homogeneous groups called strata (plural for stratum). Random samples are then selected from each stratum.

Ques-4 Not sure.

Ques-5 False. Based on the information provided within the question it seems that in this scenario Job satisfaction would be considered an intervening variable. This is a hypothetical variable used in order to explain the cause and effect relationship between two other variables. Which in this case would be the four day week leading to increased productivity. An intervening variable cannot be observed when conducting experiments which is why it is hypothetical.

Ques-6 True. An experience survey is superior to a focus group since it uses experts.

Ques 7- True. Cluster sampling breaks the population down into clusters, while systematic sampling uses fixed intervals from the larger population to create the sample. Cluster sampling divides the population into clusters and then takes a simple random sample from each cluster.

Ques-8 False.

Ques-9 True.

True or False Questions: Determine if true or false. If false why? 1) Premature efforts to treat problem behavior before determining its function can be inefficient, ineffective, and even harmful. 2) Research has found that functional analyses conducted in natural environments (e.g., classroom settings) often yield the same (or even clearer) results compared to those conducted in simulated settings. 3) Problem behavior can only be maintained by one function.
