Hello!
I am intending to perform independent samples T Test, between two groups of companies in comparing average annual growth rate in years 2002, 2003 and 2004.
Which way to calculate average growth rate is most suitable, for performing T Test later?
Data:
sales 2002 = 50
sales 2003 = 40
sales 2004 = 60
1.
[(sales 2004/sales 2002)^0,5]-1 = 0,095445115 = 9,545%
2.
[(sales 2003/sales 2002)-1 = -0,2 = -20%
[(sales 2004/sales 2003)-1 = 0,5 = 50%
average growth = (-20% + 50%)/2 = 15%
Any other method to calculate awerage growth rate?
tnx
