Chi square on a custom equation plot

Hello!

sorry if this may seem like a silly question, but I am having trouble with finding th chi^2 and reduced chi^2 values for my efficiency plot. I generated a code of my plot which i did on the curve fitting app, and I'm not sure how to go about writing in the chi^2 for it. My plot looks like this

Thank you!

I’m not very clear about the question you asked but I understand you need to find Chi-square value and reduced Chi-square value.

Formula for finding the Chi-square value is:

This can be achieved in MATLAB using this.

h = chi2gof(x)

Refer this link for the same.

You can find reduced Chi-square value through dividing the Chi-square value by degrees of freedom.

I hope this helps.
