A high-end market research firm has contacted your boss and is trying to sell some business to your organization. Upper management does not want to appear incompetent, so they have asked you to research and explain three major ways multivariate statistics are used in a business.
Provide at least 1 example of how a real company has used each of the following multivariate techniques: factor analysis, multi-dimensional scaling, and cluster analysis. Companies that provide statistics software websites and market research firm websites usually include case studies and customer testimonials.
Also, Write an e-mail explaining to upper management the chosen multivariate technique, how it is different than the other 2 techniques, how at least one other real-life company has used this technique to address a business problem and how that technique might be used at your own organization.
At the .01 significance level, can we conclude that there is more variation?
Make a pie chart or other indicator that expresses the market position of your fictitious IS business in terms of its top five products or services.
Describe how you would develop a random sample from among students.
Assume we have a population of scores with mean (mu) of 200 and standard deviation (sigma) of 10. Assume that the distribution is normal. Provide answers to the following questions:
At the end of 24 weeks of treatment, subjects were classified as responders or non-responders to treatment based on a battery of psychological tests.
The following frequency table summarizes the ages of 100 shoppers at the local grocery store. Compute the sample variance and standard deviation for this data set. Please show your work in Excel.
Determine the probability that a randomly selected sample of 31 patients would produce an average diameter of 6.6 mm or less for the non affected tendon?
Does this sample indicate a smaller average? Use α = 0.05 and assume a normally distributed population.
Provide a brief description of the main features of these data from the scatter plot and Describe why you would use performance as the predictor variable and performane related pay as the dependent variable in such a model.
A product sold by Home Depot, Inc., with an annual demand of 1000 units has Co = $25.50 and Ch = $8. The demand exhibits some variability such that the lead-time demand follows a normal probability distribution
Subjects at both sites were classified as dropouts if they left the study before the conclusion, or completers if they finished the study
