So, let’s go to “Analysis -> Exploration” and observe descriptors about a certain feature. Now we are ready for analysis! It is always a good idea to take a look at the data before performing statistical tests. Let’s delete those variables by clicking on “Variables”, selecting them and clicking on “Delete”. If you used the tables I provided in this example, you may notice some empty columns A, B and C, which were already there before importing the files. Now, if you want to import data from 2 or more files, like in this case, it is important to press CTRL/CMD and click on every file before clicking on the “Import” button at the bottom. You should get a screen like this one:īrowse your data folder. On the top left, click on the 3 dashes symbol and then click on “Import”. You could type your data yourself in the left side, but since we already have our data from elsewhere, let’s import it. And a split screen: left, where your data will live, and right, where the results will show up. You have 4 tabs: Variables, Data, Analysis and Edit. It is hardly possible to have a starting screen simpler than that. Open Jamovi and you will see a screen like the one shown below: There are also a user guide and other tutorials there! Using Jamovi

Just download it from the website and follow standard installation steps. csv files) containing data about shape descriptors. Let’s suppose I did 2 distinct segmentations and I want to compare the shapes of the black elements (yellow contour) against the white elements (red contour): Since I work with image analysis, I will use Jamovi to compare features of different elements in the following image (a sample from imageJ called “TEM_filter_sample”). They are very much alike, but here I will focus on this last one for no particular reason.

Recently, two options free and open-source emerged as a solution to this: JASP and Jamovi.
There is a free similar option to SPSS called PSPP, but since it mimics the latter, their interfaces are similar.Īnother options would be using programming languages like Python and R, but that still wards off all non-programmers. They are all very powerful platforms, but their initial interface with too many menus and buttons may intimidate new users (besides the price). Thus, popular commercial softwares, like SPSS, SAS, Origin, Stata, Prism, as well as Excel itself, have been and are used. Besides that, Jamovi is open-source and developed in R, a powerful programming language to perform statistical tests.Īlmost every field in science uses statistical analysis as a tool to validate or refuse a hypothesis. And I mean simplicity by a clean convidative interface and an easy usage.
