Correct Answer

✅ Option a — Usually mean is the best measure of central tendency.

All Options:

  • AUsually mean is the best measure of central tendency.
  • BUsually median is the best measure of central tendency.
  • CUsually mode is the best measure of central tendency.
  • DNormally, GM is the best measure of central tendency.

Detailed Solution & Explanation

**Step 1: Recall characteristics of measures of central tendency.** - **Arithmetic Mean (AM)** is the most widely used measure of central tendency. It uses all observations, is algebraically defined, lends itself to further mathematical treatment, and is least affected by sampling fluctuations. It is considered the 'best' measure for most purposes. - **Median** is useful when data is skewed or has outliers but ignores many values. - **Mode** is useful for qualitative data or finding the most common value. - **GM** is used for ratio/rate data. **Step 2: Conclusion.** The arithmetic mean is generally considered the best and most ideal measure of central tendency for quantitative data. Hence, **Option A** is the correct answer.
