2.1 The Measure of Central Tendency

In this lesson, i have learned the concepts of Mean, Median and Mode which I thought were difficult topics.... I thought it was really difficult to integrate them with Microsoft Excel but I was definitely wrong! It's a lot easier than solving using a calculator.
Through a good report of no less than Mr. Ricahard Agapay,  I learned that the measure of central tendency is a single figure which represents the general level of magnitude or values of items in a set of data. The most common concepts such as Mean, Median and Mode have become clear to me... I knew that mean is simply the average or the middle of the set of data which considered as the most reliable, most able and less probable to error. Median on the other hand is the middle value or the mean of the middle two values, when data are arranged in numerical order. "It is best to use it when the distribution  is irregular or skewed. Mode is the value or a number which appears the most. It is also possible to have more than one mode or even have no mode at all. In this topic, I also learned about weighted Mean and grand Mean.
