What is the arithmetic average, calculated by adding all values and dividing by the number of values?

• A. Mean
• B. Median
• C. Mode
• D. Descriptive Statistics

Answer: (A)

The mean is the arithmetic average. It’s a measure of central tendency obtained by adding all values together and dividing by how many values there are. This single number represents a typical value for the dataset and uses every data point in the calculation. For example, with values 2, 3, and 7, the sum is 12 and dividing by 3 gives a mean of 4. This differs from the median, which is the middle value when the data are ordered, and from the mode, which is the most frequent value. Descriptive statistics is the broad umbrella term for summarizing data, and the mean is one specific summary statistic within that umbrella.
