I would like to ask how to interpret both naturally log-transformed data and square root data after getting the results from the SPSS analysis
should I report both values as below or the back-transformed means with the CI are enough?
For square root data :
The arithmetic mean obtained from the statistical analysis of the square rooted transformed data was 2.209 with 95 % confidence interval between (1.8, 2.62) for group 1. When the data is back-transformed for proper presentation, the mean od group 1 should be 4.87 days with 95 % confidence interval between (3.24, 6.86)? simply back-transformed the value by self multiplication? is that correct?
For Natural log-transformed data (LN) :
the mean obtained from SPSS was 2.59 was a confidence interval of (1.703, 3.48)
I couldn't understand how should I report back the natural log!
could you please give me a clue on how to report such result?
Thank you
