      "From the data, we can observe that when the remote work percentage is 0 (i.e., no remote work), the average salary is approximately 162,631.52 USD. When the remote work percentage increases to 50, the average salary decreases to around 100,277.61 USD, which is a reduction of about 38.3% compared to the no-remote-work scenario. \n",

      "Based on this analysis, we can conclude that the `Machine Learning Engineer` salary in USD is negatively affected by remote positions, with fully remote positions resulting in a lower average salary compared to no remote work. However, the impact of remote work on salary is not strictly monotonic, as partially remote positions result in a lower average salary than fully remote positions. This suggests that other factors, such as company policies, industry standards, or individual circumstances, may also influence the relationship between remote work and salary.\n",
