Explain the various measures of central tendency and features of a good average.
Understand the Problem
The question is asking for an explanation of the different measures of central tendency, such as mean, median, and mode, as well as the characteristics that define a good average.
Answer
Mean, median, and mode are measures of central tendency. A good average is easy to calculate, considers all data points, is unique, interpretable, and is less influenced by extreme values.
The primary measures of central tendency are the mean, median, and mode. A good average should be easy to calculate, based on all observations, unique, and have a simple interpretation. It should also be less affected by extreme values compared to other measures.

More Information
A good average is crucial as it should represent the data set accurately with minimal bias and should be comprehensible to those analyzing the data.
Tips
A common mistake is choosing the wrong measure of central tendency for the data type, such as using the mean for skewed data which can lead to misinterpretation.
