Define multivariate analysis

In your own words, define multivariate analysis. Name the most important factors contributing to the increased application of techniques for multivariate data analysis in the last decade. List and describe the multivariate data analysis techniques described in this chapter. Cite examples for which each technique is appropriate. Explain why and how the various multivariate methods can be viewed as a family of techniques.Let A = no. of voters who are prefer candidate A in a sample then X ~ Binomial(n, 0.55). X 0.55 * 0.45 Now, p = N| 0.55, = 0.4975/ vn (Using CLT) n Now, P (p > 0.5) > 0.9 = P(p (1.2816* 0.4975/0.05)- = 162.61 Smallest sample size = n = 163.It is 0.831999 Bivariate Fit of Happiness By LifeExpectancy Happiness un 40 45 50 55 60 65 70 80 85 LifeExpectancy Bivariate Normal Ellipse P=0950 Bivariate Normal Ellipse P=0990 Bivariate Normal Ellipse P=0.950 Variable Mean Std Dev Correlation Signit.
