problem solving; to find the average of some numbers
AVERAGE IS A MIDDLE POINT OF ANY SERIES OR MID VALUE OF TOTAL DATA. WE CAN FIND AVERAGE TO ADD ALL NUMBER AND DIVIDED BY TOTAL NUMBERS YOU HAVE IN DATA
EXAMPLE:
2, 3 ,4 ,5 , 7, 9
AVERAGE = ∑ x / n
ΣX = SUM OF DATA OR NUMBERS
n = TOTAL NUMBERS OR FREQUENCY
AVERAGE = 2 + 3 + 4 + 5 + 7 + 9 = 30 ( SUM OF ALL NUMBERS OR DATA )
TOTAL NUMBERS IN COUNT OR FREQUENCY = 6
AVERAGE = 30 / 6
AVERAGE = 5
WE CAN FIND AVERAGE BY SOME OTHERS METHODS LIKE ARITHMETIC MEAN, MODE, MEDIAN. THESE ARE THE METHOD OF FINDING AVERAGE.
Let there are n numbers, if you want to find the average of those n numbers, just add those numbers and divide the sum by n.
ie s=sum of your n numbers.
then average= s/n
Let there are 5 numbers, 2,5,1,6,9
then n=5
s=23
average = s/n=23/5=4.6
