For example, what’s the annual rate of change for for the following data set: 54.0, 59.1, 62.7, 65.2, 67.7, 69.7, 71.2, 73.2, 75.7, 78.6, 81.6? Represents years 1970-1980.
Answer:
take the current year - the prior year to get the change and then divide by the prior year to get the % change.
59.1 - 54 = 5.1 / 54 = 9.44% change
Answer:
To determine the annual rate of change use the following formula:
(year2 - year 1)/(1 year)
So for the first two you would do:
(59.1-54)/1 = 5.1 is the annual rate of change
However, if you wanted to do it over several years, then you can just do:
(Final Year - Initial year)/(number of years)
Hope this helps!
