Q

What are examples of biases you must take into consideration when drawing conclusions from the data?

A
  • selectivity -> leads to overconfidence in the data
  • co-occurrences -> misconstrued as correlations or causal relationships
  • extrapolating the rate of instances in the population from those being observed
  • some sources may be unreliable

26
Q

List the steps in the hypothesis testing process.

A
  1. determine Ha and Ho.
  2. determine type of test (t,Z,chisquared).
  3. determine level of significance (alpha).
  4. compute the test statistic.
  5. compute the critical value.
  6. compare the test statistic and the critical value.
  7. reject or retain the null.
  8. state the answer in terms of the marketing research problem.
27
Q

The test of means is for what kind of variable?

A

continuous variables

28
Q

The test of proportions is for what kind of variable?

A

categorical variables

29
Q

This kind of analysis has to do with evaluating ONE survey question.

A

univariate

30
Q

This kind of analysis has to do with evaluation TWO+ survey questions.

A

multivariate

31
Q

What are the univariate data analysis techniques?

A

metric and non-metric

32
Q

What are the multivariate data analysis techniques?

A

dependence and interdependence

33
Q

This data analysis technique measures the strength of a linear association between two metric (continuous) variables.

A

correlation

34
Q

This data analysis technique analyzes a metric independent variable and a metric dependent variable.

A

regression

35
Q

This data analysis technique determines if one variable depends on or influences another.

A

regression

36
Q

This data analysis technique analyzes a set of metric independent variables and a non-metric dependent variable.

A

discriminant analysis

37
Q

This data analysis technique groups objects or people in regard to certain variables.

A

cluster analysis

38
Q

This data analysis technique takes the info contained in a larger set of metric variables and summarizes it into a smaller set of summary factors.

A

factor analysis

39
Q

This data analysis technique determines the ‘ideal’ combination of attributes and levels for a new product.

A

conjoint analysis

40
Q

Goals: degree of association, direction of association

These are the goals for…

A

correlation

41
Q

Goals: measure influence (explanation), predict values for dependent variable

These are the goals for…

A

regression

42
Q

Goals: classify people into groups based on their values of the independent variables

These are the goals for…

A

discriminant analysis

43
Q

Goals: those within a group are similar and those outside a group are different

These are the goals for…

A

cluster analysis

44
Q

Goals: simplify data, reduce a set of variables

These are the goals for…

A

factor analysis

45
Q

Goals: tradeoffs among attributes and level of attributes are examined to understand what consumers prefer

These are the goals for…

A

conjoint analysis

46
Q

“Are quality perceptions related to price perceptions? And if so, in what direction?”

This is an example question for…

A

correlation

47
Q

Why does correlation not necessarily equal causation?

A

In order for causation to occur, you must have all three:
- correlation
- temporal sequence
- non-spurious association

48
Q

“Do price perceptions influence quality perceptions?”

This is an example question for…

A

regression

49
Q

“What factors influence choice?”

This is an example question for…

A

discriminant analysis

50
Q

Choice models are used for…

A

discriminant analysis

51
Q

Segmentation is another word for…

A

cluster analysis

52
Q

Perceptual maps are used for…

A

factor analysis

53
Q

“What is the ideal combination of chocolate type, filling, and amount of nuts for a new candy bar?”

This is an example question for…

A

conjoint analysis

54
Q

Why should you caution when using a conjoint analysis?

A

adding attributes / levels exponentially increases the product combinations evaluated

(think of the chocolate bar example!)

55
Q

What are the three types of readers of a final report?

A
  1. those who only read the executive summary
  2. those who read the executive summary and the body of findings
  3. those who read the entire report and appendix
56
Q

Amongst presentation barriers, what is selective perception?

A

When the client hears what they want to hear as a conclusion of the data instead of what is actually true.

consumer wants and needs are always changing
