Let me define some stuff first.
Y-axis: number of times reached value on the x-axis
Orange bars: Object #1
Gray bars: Object #2
Right vertical line: mean for object #1, mean = 85.85
Left vertical line: mean for object #2, mean = 63.85
Standard deviation for object #1: 1.5
Standard deviation for object #2: 2.8
Now, most of that data is useless to you guys, but how should I go about representing the standard deviation around each object's mean? The standard deviation has to do with the x-axis by the way.
The reason I ask this question is because of this sentence in one of my books: "Mark the standard deviations around the mean for each object and add a horizontal line to show this for each object."
I thought that these deviations would be other vertical lines, but that sentence says otherwise.
Thanks for any help.
