Multivariate analysis
  • 1. Multivariate analysis is a statistical technique used to analyze data sets that contain observations on multiple variables. It allows researchers to understand the relationships between these variables and uncover patterns or trends that may not be apparent when analyzing each variable individually. By examining multiple variables simultaneously, multivariate analysis provides a more comprehensive and holistic understanding of the data, enabling researchers to make more informed decisions and draw reliable conclusions. Common methods of multivariate analysis include principal component analysis, factor analysis, cluster analysis, and multivariate regression. These techniques are widely used across various fields such as economics, psychology, biology, and marketing to explore complex relationships and extract meaningful insights from data.

  • 12. When can principal component analysis be appropriate to use in multivariate analysis?
A) When dealing with categorical data only
B) When variables are independent
C) When variables are highly correlated
D) When outliers are present
  • 13. What does a scree test help determine in factor analysis?
A) The number of factors to retain
B) The significance of variables
C) The standard deviation of variables
D) The correlation between variables
  • 14. How is MANOVA different from ANOVA in multivariate analysis?
A) MANOVA considers multiple dependent variables simultaneously, while ANOVA focuses on a single dependent variable
B) MANOVA is used for categorical data analysis, while ANOVA is used for continuous data analysis
C) ANOVA uses mixed-effect models, while MANOVA uses fixed-effect models
D) ANOVA is appropriate for small sample sizes, while MANOVA is for large sample sizes
