The one which is the measure of the central tendency is

Options

A. mode
B. mean deviation
C. standard deviation
D. coefficient of correlation

Answer

To determine which option is a measure of central tendency, we need to understand what central tendency means and identify the correct option among the provided choices.

### Step-by-Step Solution:

1. **Understanding Measures of Central Tendency**:
- Measures of central tendency are statistical measures that describe the center or typical value of a dataset. The most common measures include the mean, median, and mode.

2. **Analyzing the Options**:
- **Option 1: Mode** - This is a measure of central tendency that represents the most frequently occurring value in a dataset.
- **Option 2: Mean Deviation** - This is a measure of dispersion that indicates the average distance of each data point from the mean. It is not a measure of central tendency.
- **Option 3: Standard Deviation** - This is also a measure of dispersion that quantifies the amount of variation or dispersion in a set of values. It is not a measure of central tendency.
- **Option 4: Coefficient of Correlation** - This measures the strength and direction of a linear relationship between two variables. It is not a measure of central tendency.

3. **Identifying the Correct Option**:
- Among the options provided, only the mode (Option 1) is a measure of central tendency. The other options relate to dispersion or correlation, not central tendency.

### Final Answer:
The measure of central tendency among the given options is **Option 1: Mode**.
