Identifying Measures of Central Tendency
Which of the following is not a measure of central tendency--
- Arithmetic mean
- Median
- Range — Correct Answer
- Mode
Explanation:
Correct Answer: Range
Range is a measure of dispersion, not a measure of central tendency. Mean, Median, and Mode are the three measures of central tendency as they describe the central position of a dataset.
Classification of Statistical Measures
| Category | Measures |
|---|---|
| Central Tendency | Mean (Arithmetic, Geometric, Harmonic, Weighted), Median, Mode |
| Absolute Dispersion | Range, Variance, Standard Deviation, Mean Deviation |
| Relative Dispersion | Standard Error (SE), Coefficient of Variance (CV) |
Key Notes on Central Tendency
- Most stable: Mean (uses all observations)
- Not rigidly defined: Mode (can be multimodal or absent)
- Least affected by extremes: Median
Why Other Options Are Wrong
- Arithmetic Mean → IS a measure of central tendency (most commonly used)
- Median → IS a measure of central tendency (middle value of ordered data)
- Mode → IS a measure of central tendency (most frequent value)
