Can we run an ANOVA if we have only "cero" values (0) in some treatments?

Lets say we have 5 treatments, and 4 replicates per treatment. However, we have "cero values" (0) in 3 of the treatments and then at least numbers in the other 2 treatments. We are getting some...

What transformation shall I apply to data expressed in percentage before running stats on those?

I have raw data expressed in their respective units, but I am interested in testing if the contribution to a total value change with my treatment. Therefore, more than if the number is different I...

In mixed effects model, (R) what exactly implies that the response variable (RV) relates to the predictors as + or as *?

I am trying to test if a scaling relationship (oxygen consumption vs body weight) chance under different conditions (say 1,2,3,4,5,6,7). All conditions were tested in the same animals and...

How can I statistically test if a slope (scaling) extracted from my data set (n=78) is different from a theoretical value (i.e. 0.75)?

Hi all, I will appreciate your statistical advise on how to compare a slope extracted from my data set, therefore with 95% CI, is it different or equal to a theoretical value (i.e 0.75)? Huge thanks!

We have been examining pH in the gut of a small marine isopod and have been finding pH to be just slightly to the acid side of neutral. I suggest you contact [email protected] to discuss.

crustaceans like shrimps posses gut pH almost 7.2 to 7.4

Miloš Buřič

The optimal values are naturally about 7, but pH decrease below 6 can affect problems during and after molting, because of further calcification.

Lethal values are much lower (even below 4), in accordance to different species tolerance.

In the land crabs Gecarcoidea natalis and Discoplax celeste the foregut ph values were 6.69 and 6.03 respectively. See Linton and Greenaway 2004 Journal of Experimental Biology . 12/2004; 207(Pt 23):4095-104.
