Exam 18: Multivariate Data Analysis

A client wanted to know which preventive health care information (PHC)sources were related to each other.The following table has factor loadings for 10 types of preventive health care information using a Varimax rotation.Based on the table of results below,what would you tell your client?

Collinearity is a situation in which independent variables are heavily correlated with each other.

______________ is a measure of the percentage of the variation in the dependent variable that is explained by the variation in the independent variables.

In factor analysis,the correlation between factor scores and the original variables is known as the factor ________,

Dummy variables created to include nominally scaled variables in an analysis are commonly used in:

The coefficient of determination is normally associated with which of the following multivariate procedures?

In factor analysis,naming factors is a somewhat subjective step,combining intuition and knowledge of the variables with an inspection of the variables that have high loadings on each factor.

Cluster analysis is useful for clustering groups of questions together into factors.

An insurance company wants to know whether the subscribers to its HMO,PPO,or traditional single indemnity plan exhibit better health characteristics.They have the following data for each of their subscribers: % of body weight over optimum weight; blood pressure; cholesterol and hours per week of exercise.The analysis will group subscribers as either healthy,somewhat healthy or not healthy.Which of the following would be the best procedure for making such a determination?

Which of the following is not a step in conjoint analysis?

In the multiple regression formula,which of the following represents the dependent variable?

Suppose an analyst wanted to determine whether or not dollars spent on advertising,number of sales people,number of new products introduced,and dollars spent on research and development were contributing to the growth in company market share.Which of the following procedures would be most appropriate?

Independent variables are important components in multiple regression analysis and ________________.

In order to make valid comparisons of regression coefficients,the coefficients must be scaled in the same units,or be standardized.

If the goal of an analysis is to group respondents into mutually exclusive and collectively exhaustive subgroups,the preferred procedure would be cluster analysis.

Summarizing a number of survey questions into a single concept could be achieved with which type of analysis?

Predictive analytics do not apply to big data.
