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

25
Which variables are categorical?
nonmetric. nominal and ordinal.
26
List the steps in the hypothesis testing process.
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
The test of means is for what kind of variable?
continuous variables
28
The test of proportions is for what kind of variable?
categorical variables
29
This kind of analysis has to do with evaluating ONE survey question.
univariate
30
This kind of analysis has to do with evaluation TWO+ survey questions.
multivariate
31
What are the univariate data analysis techniques?
metric and non-metric
32
What are the multivariate data analysis techniques?
dependence and interdependence
33
This data analysis technique measures the strength of a linear association between two metric (continuous) variables.
correlation
34
This data analysis technique analyzes a metric independent variable and a metric dependent variable.
regression
35
This data analysis technique determines if one variable depends on or influences another.
regression
36
This data analysis technique analyzes a set of metric independent variables and a non-metric dependent variable.
discriminant analysis
37
This data analysis technique groups objects or people in regard to certain variables.
cluster analysis
38
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.
factor analysis
39
This data analysis technique determines the 'ideal' combination of attributes and levels for a new product.
conjoint analysis
40
Goals: degree of association, direction of association These are the goals for...
correlation
41
Goals: measure influence (explanation), predict values for dependent variable These are the goals for...
regression
42
Goals: classify people into groups based on their values of the independent variables These are the goals for...
discriminant analysis
43
Goals: those within a group are similar and those outside a group are different These are the goals for...
cluster analysis
44
Goals: simplify data, reduce a set of variables These are the goals for...
factor analysis
45
Goals: tradeoffs among attributes and level of attributes are examined to understand what consumers prefer These are the goals for...
conjoint analysis
46
"Are quality perceptions related to price perceptions? And if so, in what direction?" This is an example question for...
correlation
47
Why does correlation not necessarily equal causation?
In order for causation to occur, you must have all three: - correlation - temporal sequence - non-spurious association
48
"Do price perceptions influence quality perceptions?" This is an example question for...
regression
49
"What factors influence choice?" This is an example question for...
discriminant analysis
50
Choice models are used for...
discriminant analysis
51
Segmentation is another word for...
cluster analysis
52
Perceptual maps are used for...
factor analysis
53
"What is the ideal combination of chocolate type, filling, and amount of nuts for a new candy bar?" This is an example question for...
conjoint analysis
54
Why should you caution when using a conjoint analysis?
adding attributes / levels exponentially increases the product combinations evaluated (think of the chocolate bar example!)
55
What are the three types of readers of a final report?
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
Amongst presentation barriers, what is selective perception?
When the client hears what they want to hear as a conclusion of the data instead of what is actually true.
57
Why is research always needed?
consumer wants and needs are always changing
