    Graph Interpretations/Analysis Help

    Can someone please help me interpret these statistical results provided by the graphs represented on the pdf format? I do not know statisics very well and need a bit of help interpreting these results and a small analysis as well. Need to write an essay about this analysis, but I do not know what it is because I don't know how to interpret them. Thanks!

    Is it the Box and Whisker or the ANOVA that troubles you the most?

    Box and Whisker has five features:
    1) Heavy bar should be the median value
    2, 3) Shaded bars above and below are the middle quartiles
    4, 5) Lines extending beyond the shading are the extreme quarties.

    Unfortunately, your chart has another feature and it looks a little odd. It may be a variation:
    1) Heavy bar should be the meean value.
    2, 3) Shaded bars above and below are one standard deviation.
    4, 5) Lines extending beyond the shading are the 2nd and 3rd stardard deviations.
    6) Little circles may be outliers - possibly anomalous results.
