Missing $ inserted? Why?

Question

I am getting this error in my table, but I don’t know why?

\begin{table*}[htbp]

You can't use \pm outside of math mode. Maybe have a look at the siunitx package to properly display your values and uncertainties. And please also have a look at https://tex.stackexchange.com/questions/425453/why-not-scale-elements-that-contain-text And maybe you want to read up on significant figures... — samcarter_is_at_topanswers.xyz, Jul 10 '23 at 15:41
Thank you alot, done! you cant imagine how this simple error took my time...Really appreciate — TinaTz, Jul 10 '23 at 15:54
Mostly off topic, but you shouldn't rescale a table. It makes the fonts different throughout your document. (And if you remove the scalebox, then the error shows up at the correct spot.) — Teepeemm, Jul 10 '23 at 16:31

Just change $\pm$. Have a look to the following code:

\usepackage{caption}
\usepackage{booktabs}
\usepackage{graphicx}
\begin{document}

    }
\end{table}
\end{document}

Which produces the next output:
