| Apr 15, 2022 at 21:34 | comment | added | Axxxxx | The errors are the accumulation of instrumental errors in observation. These are all mainly observational errors | |
| Apr 15, 2022 at 18:17 | comment | added | whuber♦ | It would be nice to know what the errors mean and how they are determined. | |
| Apr 15, 2022 at 18:03 | comment | added | Axxxxx | I updated the problem and included the actual data. When it comes to the assumptions about the errors I'm not exactly sure since in both X and Y there are data points with high errors. | |

| Apr 15, 2022 at 14:16 | comment | added | EngrStudent | Welcome to CV. The following link is step-by-step through bkm for linear fits using the R software tool. Personally I use R in the RStudio IDE, which are both free. It is a solid data-analysis tool. Link: learnbymarketing.com/tutorials/linear-regression-in-r | |

| Apr 15, 2022 at 9:59 | comment | added | dipetkov | The problem statement is not clear. Can you show with an example exactly what data you have for each data point and say what assumptions you are willing to make about these errors. | |
| Apr 15, 2022 at 9:50 | comment | added | Axxxxx | I don't think its possible for me to ignore the error in x | |
| Apr 15, 2022 at 9:26 | comment | added | frank | If you are willing to ignore the error in $x$, you could use en.wikipedia.org/wiki/Least_squares#Uncertainty_quantification | |

| Apr 15, 2022 at 9:18 | comment | added | Axxxxx | Least square method | |
| Apr 15, 2022 at 9:09 | comment | added | Axxxxx | Used excel to compute it and it doesn't add the error to the equation | |
| Apr 15, 2022 at 9:03 | comment | added | frank | It depends on how you compute your "best fit line". | |
