I want to perform a multiple regression in SPSS. The tables and data look fine. However, this scatter plot is coming out.
What am I doing wrong? Or is it possible that such a diagram exists? If so, how do I interpret it?

Guys, I'm really confused again. I'm stuck on this problem because I need the current for all the formulas. I don't know how to calculate it.
I don't really understand how to calculate this. If possible, could you please explain the intermediate steps so that I can understand it better? Ps Yes, I know there's an equation underneath that might seem to fit. But I don't know how it's supposed to fit…
Thank you. ❤️❤️^^^^^^
I don't understand the task in general
A property needs to be fenced. It is 22.5 m long and 16 m wide. How many meters of fence are needed if the gate is 3 m wide?
There are exactly 49 possible value combinations, of which 48 were actually present.
In the present form, it is not possible to distinguish optically whether, for example, x=1 / y=0, there are now one or two or perhaps also 100 cases, because the individual cases are superimposed.
In the diagram editor of the SPSS software you can Options -> Class/group and can be displayed either by the size or by the color intensity of the markings, where many or fewer cases lie.
You could also try a little “shrinking” (jitter) into the data, so that cases with the same coordinate are slightly shifted relative to each other, but this is in the newer SPSS versions, as far as I know, only to make via the Graphs Chart Builder.
