Today, I’ll introduce how to filter variables after uploading data to SAS Studio. First, let’s upload data to SAS Studio. I’ll summarize data based on Treatment_modified. I want to summarize for each unique ID. So, I’ll add numbers from 1 up to the end. and I’ll summarize data again. Then, I’ll download this data to my PC. 1) to upload data to SAS First, let’s upload the data to SAS. I’ll assign this data to the Test table that I…
SAS Studio is a web version of the SAS program, and it can be used for free. As my current license for the statistical program I’ve been using is about to expire, I was searching for alternatives. Upon discovering SAS Studio, I decided to give it a try. Although I have never used SAS before, I’ve decided to take this opportunity to learn. I will now summarize the very basic learning materials I have covered up to this point. First,…
I will introduce how to perform a Two-Way ANOVA analysis using SAS Studio. Here is the data that you have available: Upload this Excel file to SAS Studio. After uploading the Excel file to SAS Studio, create a data table named “EXP1” in My Libraries. Then, click on the EXP1 data table. Then, select the icon for generating code located at the top. By doing so, a new tab named “Program 1” will be created, allowing you to generate the…
Today, I will explain the meaning of the F-value in testing for significance through statistical processing. Let me give you an example. Suppose we want to determine whether there are differences in the yield according to the varieties (A, B, C). The total experimental unit is 12 (3 varieties x 4 replicates). What would happen if there is a significant difference in yield among varieties A and C? If there is a large difference in yield between these varieties, the…
In my previous post, I explained what split-plot design and the statistical model is, and also how it is different RCBD. What is split-plot design in agronomy research? I explained the main difference between split-plot design and RCBD is that in split-plot design, error is divided into two (error a and b), increasing the significance of interaction between the main plot and sub-plot. Now our interest lies in cases where we have three factors. In a split-plot design, we typically…
