What is the most common type of average?

  1. Mean

  2. Median

  3. Mode

  4. Range

The correct answer is: Mean

The most common type of average is the mean. This is because it is calculated by summing all the values in a data set and dividing by the number of values, giving a representative value of the whole set. Other types of average, such as the median and mode, are less commonly used and may not accurately reflect the entire data set. The range, while it can give an idea of the spread of the data, does not provide a representative value and can be heavily influenced by outliers. Therefore, the mean is the most commonly used type of average and is generally considered the most reliable measure of central tendency.
