I have an odds ratio that is 0.88 (95% CL: 0.78,0.99). I'm keeping decimals to 2 places, so is it technically still fair to consider the OR estimate statistically significant (since it still doesn't contain 1.0 when using 2 decimal places)? Or for publication purposes, would something like this be downplayed?
Some journals address issues related to rounding in their author guidelines. Usually that guidance is related to p values, but I would recommend looking to see if the target journal makes reference to the presentation of statistics such as odds ratios.
ANOVA, or Analysis Of Variance, is used to compare the averages or means of two or more populations to better understand how they differ. Watch this tutorial for more.
