Study Notes
Measures of Central Tendency
- Mean, Median, and Mode provide information about the central tendency of a variable.
Measures of Skewness
- Skewness measures the lack of symmetry in a normal distribution.
Descriptive Statistics
- Descriptive statistics alone do not tell us about the relationship between variables.
Focus of Econometrics
- The focus of econometrics is to study the empirical relationships between economic variables.
Economic Theory or Hypothesis
- Economic theory or hypothesis aims to study the underlying mechanisms and behaviors that drive economic phenomena.
Normal Distribution
- A bell-shaped curve represents a normal distribution.
Measures of Variability
- Variance and Standard Deviation measure the spread or variability around the central tendency of a variable.
