Help with drawing gradients along error bars

Click For Summary
SUMMARY

The discussion centers on the proper representation of gradients in relation to error bars in a dataset exhibiting a linear trend. The user has drawn y-axis error bars and a trendline without statistical methods, but questions the acceptability of maximum and minimum gradients that do not encompass all error bars. The consensus is that while it is common for gradients to not intersect all error bars, adjustments to error values should not be made solely for visual conformity. Maintaining the integrity of the data is paramount.

PREREQUISITES
  • Understanding of linear regression and trendlines
  • Familiarity with error bars in data visualization
  • Basic knowledge of statistical significance
  • Experience with graphing tools or software (e.g., Excel, R)
NEXT STEPS
  • Research methods for calculating gradients in linear regression
  • Learn about the implications of error bars on data interpretation
  • Explore best practices for visualizing data with error margins
  • Investigate statistical software options for automated error bar calculations
USEFUL FOR

Data analysts, researchers, and students involved in statistical analysis and data visualization who need to accurately represent trends and error margins in their datasets.

Homework Statement



I have a set of data which clearly shows a linear trend. I've hand-drawn the y-axis error bars for the data (x-axis errors are negligible), and a trendline (without any mathematical/statistical techniques). The trendline stays well within each of the error bars.

However, I'm also supposed to draw maximum and minimum gradients. And I've noticed that these gradients completely miss out some of the error bars.

Is that usually acceptable? Or should I change some of the error values just so that the max and min gradients stay within all the error bars?
