What is central tendency |
| Answer» Often in statistics, we tend to represent a set of data by a representative value which would approximately define the entire collection. This representative value is called as the measures of central tendency. The name itself suggests that it is a value around which the data is centered. The measures of central tendency are given by various parameters but the most commonly used are mean, median and mode. | |
