The 85 95 thing?

I have a hard time interpreting the graph

ok so this is the rule i guess 68% of data falls within the first standard deviation from the mean. 95% fall within two standard deviations. 99.7% fall within three standard deviations.

hard to explain without giving away the answer, but I'll try the middle 95% of the data means two standard deviations above and below the mean |dw:1434758722642:dw|

each vertical line marks one standard deviation either above or below the mean

Alright i'm following along kind of

  • Vocaloid
the "endpoints" are: 1) the value which is 2 standard deviations below the mean and 2) the value which is 2 standard deviations above the mean

ah so 4.2 and 11.4?
