1. ### Repeated measure and blocking together

Hi I am considering using a batch for each unit of 4 runs of total 16 runs, therefor I will have a total of 4 different batches (blocks). This to account for the variations found in different batches. I want to do it as it will be expensive to use 16 different batches. I also want to repeat the...
2. ### Repeated measures, samples and control groupe

Hi all Right I am struggling with understanding the concept behind some statistic when I deal with this problem; I have an experiment where I want to understand how long it take a fluid to reach a specific temperatur and how it effects its nutritional content when during a heating process. So...
3. ### Experimental Design

I only have n= 2 in this design so I should actually consider increasing it?
4. ### Experimental Design

That make sense! Thank you. I have another question :) I choose that the factor A is fixed as the material will origin from only 3 different composition (A1,A2,A3), B will also be fixed as I will only investigate three thicknesses of each material and also the machine will be fixed. However...
5. ### Experimental Design

I want to investigate the effect of material 1 on all levels of thickness and machine before the treatment and after and the same for material 2 and material 3. So it is only the material that change, but the other factors will be inside each level of material and this will be repeated 2 times...
6. ### Experimental Design

I want to investigate if some of these factors (A,B,C) can optimize the warming process in terms of time and nutritional content of some food when using different material of a container A (material1, material2, material3), different thickness of container B (thickness1, thickness2) and...
7. ### Experimental Design

Hi everyone I am trying to figure out the best possible way to design an experiment I am interested in. I want to investigate the effect of three factors (A,B,C) and A has 3-levels, B has 2-level and C has 2-level and we will have 2 runs. I want to investigate these factors before a treatment...
8. ### Evalution of recored temperatures before and after

The heating period depends on the amount of volume in each bottle. We had 8 bottles with different sizes and volumes of fluid :) Temperature before <-- x(32, 36, 41, 42, 37, 37, 38, 37) Temperature after <-- x(32, 33, 35, 41, 38, 33, 37, 35)
9. ### Evalution of recored temperatures before and after

Thank you very much! but why can I not use paired t-test? I know that due to the small sample size it is difficult to assume whether the data is normal or non-normal distributed. So of course based on this, we can do a non-paramatic test, but is this the case every time we have a small sample size?
10. ### Evalution of recored temperatures before and after

Hi I have recorded the temperature of a fluid in a container before and after heating, and want to evaluate the significance by looking at the mean differences of the temperature before and after using SAS jmp. I used 8 different samples and from them I recorded the temperature before and...
