Averages

Averages

1. There are 3 types of averages

   • They are mode, median and mean
     • Mode
       • Mode is the most common number in a sequence
         • Example 2,4,2,7,10
           • The mode would be 2
             • There can be no mode or more than one mode
     • Median
       • The median is the average of a group of numbers that is in order from smallest to largest
         • Example 2,3,4,6,7
           • So the median would be 4
             • But if there is an even amount of numbers
               • Example 3,6,8,9,10,11
                 • What you have to do is add the 2 numbers in the middle and then divide them by 2
                   • So 8 + 9 / 2
                     • So the median would be 8.5
     • Mean
       • The mean is when you add up all the numbers in the group then divide it by the number of numbers there are
         • Example 1 + 4 + 6 + 8 + 4 = 23 / 5 = 4.6
