Which type of analysis, involves describing a case in terms of a single variable-specifically ?

The correct answer is - Univariate analysis

Key Points

• Univariate analysis
  • Univariate analysis focuses on analyzing a single variable at a time.
  • The primary goal is to describe the variable using statistical measures like mean, median, mode, range, and standard deviation.
  • This type of analysis is used to summarize the data and identify patterns in one specific variable without considering relationships with other variables.
  • Examples of univariate analysis include:
    • Calculating the average age of a group of people.
    • Finding the distribution of test scores in a class.

Additional Information

• Bivariate analysis
  • Involves analyzing the relationship between two variables.
  • It is used to determine how one variable affects or correlates with another.
  • Methods include scatter plots, correlation coefficients, and regression analysis.
• Multivariate analysis
  • Focuses on analyzing more than two variables simultaneously.
  • It is used to study complex data relationships, such as in predictive modeling and factor analysis.
  • Examples include multiple regression and cluster analysis.
• Cross analysis
  • Also known as cross-tabulation, it compares data across different categories of a single or multiple variables.
  • It is widely used in market research and surveys to analyze the relationship between categorical variables.
