Which central tendency has been used to arrive at the following statements?
The most common price of a certain type of calculator is 125.

Answer

To determine which central tendency has been used in the statement "The most common price of a certain type of calculator is 125," we can follow these steps:

### Step 1: Understand Central Tendency
Central tendency refers to a statistical measure that identifies a single value as representative of an entire dataset. The most common measures of central tendency are mean, median, and mode.

### Step 2: Identify the Measures
- **Mean**: The average of a set of numbers, calculated by adding all the values and dividing by the number of values.
- **Median**: The middle value when the numbers are arranged in order. If there is an even number of values, the median is the average of the two middle numbers.
- **Mode**: The value that appears most frequently in a dataset.

### Step 3: Analyze the Statement
The statement mentions "the most common price," which indicates that we are looking for a value that occurs with the highest frequency in the dataset of calculator prices.

### Step 4: Determine the Appropriate Measure
Since the statement refers to the "most common price," it aligns with the definition of mode. The mode is specifically used to identify the value that appears most frequently in a dataset.

### Conclusion
Therefore, the central tendency used to arrive at the statement "The most common price of a certain type of calculator is 125" is **mode**.
