1. Measures of Central Tendency – Where is the center of the data?
- Mean: The average (sum of all values divided by the number of values).
- Median: The middle value when the data is ordered.
- Mode: The most frequently occurring value.
2. Measures of Dispersion – How spread out is the data?
- Range: Difference between the highest and lowest values.
- Variance: Average of the squared differences from the mean.
- Standard deviation (SD): Square root of the variance; indicates how much values deviate from the mean.
- Interquartile range (IQR): Difference between the 75th and 25th percentiles (Q3 - Q1).
3. Shape of Distribution
- Skewness: Measures the asymmetry of the data distribution.
- Kurtosis: Measures the "tailedness" of the distribution.
I'm mostly interested in the kurtosis (that's why I polled it):
