not always. the average is only one measure of central tendency. depending on the nature of your data, other measures like median (the middle value) or mode (the most occurring value) might be more appropriate. if your data has extreme values or is skewed, the median or mode can provide...
For example, in cooking, a cup is a measure for volume. Measurement, on the other hand, is the act or process of applying this standard to determine the size, length, or amount of something. It's about the action and its result. For instance, measuring flour involves using a cup to ...
