PPI

PPI stands for Point Per Inch. PPI is the number of dots per inch in a printer's resolution or the number of pixels per inch in a monitor's screen resolution. The more PPI, the higher your image quality will be as it becomes sharper and clearer. The lower your PPI, the lower your image quality will be, and the more likely you'll see individual pixels in an image.

Affinity Diagram

A data visualisation tool that can be used to explore and group people's thoughts or reactions to a set of concepts. Affinity diagrams are often used in user research and design thinking as an experimental technique for generating new ideas or solutions.

The emergent patterns in these visual representations can help identify which aspects your audience will respond well to, thus enabling decisions on the information architecture and next steps in the process.

It is important to note that affinity diagrams were initially developed for qualitative research but have since been adapted for quantitative research (though they are not typically used with statistical data).
