What is an Error Bar? An error bar is a line through a point on a graph, parallel to one of the axes, which represents the variation or spread relative to corresponding point (which is usually a central tendency, such as mean). In IB Biology, the error bars most often represent the standard deviation of a data set relative to the mean.

When assessing the habitat with the lowest soil temperature, it is inconclusive between boy field and sandpit field. While Hayfield conclusively has the highest soil temperature, the data for boy field and sandpit field overlap, making it challenging to determine the habitat with the lowest temperature definitively.
