Question

BlackTom AI · Accepted Answer

The question asks: 'The average value of a set of numbers is known as which of the following?' The options are:
- Mode
- Mean
- Median
- Standard Deviation

Option 1: Mode. The mode is the value that appears most frequently in a data set. It does not describe the average or central tendency in the general sense of averaging all values, so this is not the correct characterization of 'average.'

Option 2: Mean. The mean is the sum of all numbers divided by how many numbers there are, which is the standard mathematical definition of the average value of a data set. This aligns exactly with the term 'average value.'

Option 3: Median. The median is the middle value when the data are ordered from smallest to largest. It represents a measure of central tendency that may differ from the mean, especially in skewed distributions. It is not the same as the average value.

Option 4: Standard Deviation. The standard deviation measures the amount of variation or dispersion in a data set, i.e., how spread out the values are around the mean. It is not the average itself, but rather a statistic describing spread.

In summary, the term that corresponds to the average value of a set is the mean, while the other options refer to different statistical concepts related to central tendency (mode, median) or dispersion (standard deviation).
