Mean,Median,Mode,Range

There are four ways of measures of central tendency. I will start with mean. Mean in math means the average like 1+2+3+4+5=15 divided by 3=5. Median in math is the middle of a bunch of numbers like 1,3,5,7,9. The middle of these number is 5. If there are six numbers then we go back to mean, foror example: 1,2,3,3,5,6 the two threes will be added and divide by two and the midian will be three. Mode in math means the most number shown. First you have to arrange the numbers from least to greatest, for example: 1,1,2,2,3,3,3 the mode will be three. The range is the distance between. First arrange the numbers from least to greatest then find the lowest and the highest number then minus the two number, for example: 1,2,3,4,5,6 6 will is the highest and 1 is the lowest 6-1=5 5 will be your range. That is the 4 ways of measures of central tendency.
