error bars
Data confidence markers
Error bars are graphical lines extending from data points on a chart, showing the range of uncertainty or variability in the measurements.
They typically represent standard deviation, standard error, or confidence intervals.
Short error bars suggest precise, reliable data; long ones indicate more uncertainty: The error bars overlap, so the difference isn't statistically significant.
