Averages are called measures of central tendency because they represent a central point or typical value within a dataset. They summarize a large set of data with a single value that reflects the general trend or distribution, making it easier to understand and compare different datasets. Common types of averages, such as the mean, median, and mode, provide insights into the overall behavior of the data, highlighting its central location.

What is statistical average?
average is defined as a single value which has tendency to represent the data as a whole. averages are also called "measure of central tendency" or "measure of location"
Why do you need the mean in maths?
The mean is one of the measures of central tendency. The other standard ones are the median and the mode. They each have their strengths and weaknesses. For the mean, also called the average, the idea of central tendency is this: every number that has gone into calculating the average has the same unweighted effect on the final average. Of course, the numbers that are out at the extremes can seem to have more pull, but you don't actually do anything different with those numbers. They are all treated exactly the same. You add all the data points together, and then divide that sum by the number of data points. So the mean represents equally each of the data points used in its calculation.This is a very important idea in statistics, where you figure out how to use measures of central tendency and other measures to say some surprisingly powerful things about the data you collect.
If a central angle measures 180 degrees then what is it called?
180 degrees is a straight line
If a central angle measures 180 degrees what is it called?
An angle of between 90 degrees and 180 degrees is called an obtuse angle, an angle that is exactly 180 degrees is called a straight angle (because it creates a straight line), and an angle of more then 180 degrees is called a reflex angle.
What type of angle measures 90?
If it measures 90 degrees, then it is called a right angle.
