What average measure would you use to find the spread of marks in an examination?
The answer is mode
How do you find average spread to the nearest hundredth?
There are several different measures of average spread: the standard deviation is the most common but average absolute deviation is another possibility. You could also have total ranges or inter-quartile ranges from sets of observations, each one being a measure of spread. Their averages would also be average spreads. You would have to calculate the average spread according to whichever definition you wanted and then round up or down to 2 decimal places (or the nearest hundredths).
Why you measure standard deviation?
The idea is to know how much the values "spread out" from the average.
Find the average of 132 140 145 128?
Find the average of 140
What does the average spread mean in math terms?
Line all the numbers in order, find their average, then subtract the average from each of the numbers (If you have any negative numbers, take the minus sign off to make them positive), then add all the answers up, then divide by the number of values. Example: 100-88=12 95-88=7 90-88=2 85-88=3 80-88=8 75-88=13 12+7+2+3+8+13=45 45/6=7.5 Average=87.5=88 Average spread=7.5
