Combined Analysis

Question

Hello, is there anyone help me about how can I perform combined analyze about agricultural research. I conduct a research in randomized block design with 4 different level of irrigation water amount and 3 replicates and I performed it for 3 years respectively in the same field. I want to see homogeneity situation over the years and if there is years interaction with treatments and if there is how can I perform duncan groups. Thanks in advance.

My recommendations...

First of all, get your data into JMP and in a useful format. See attached data tables. The stacked format is probably most useful. I used the Excel Import Wizard, Tables > Stack and Cols > Recode... tools in JMP to create these. Look them up. @jules has some good resources for learning about data preparation: Advanced Data Preparation: 10 Essential Tools in JMP(R) to Get From “Messy” to “Analysis Ready” ( 2019-EU-TUT-143 )

Alternatively you could just collect your data in the stacked format in the first place.

Then visually explore the data before you do any statistical tests:

My advice is to learn how to do this and then learn how to do the statistical tests.

I hope this helps.
