Post by: sweetest angel on May 13, 2010, 10:07:49 am

guys doing paper5, while drawing error bars, u miltply standard error by 2 and then draw up and down the bar graph or is it just drawing up and down.

for example if standard error is 0.1, u draw +/- 0.1 or is it 0.1x2=0.2 and then u draw +/- 0.2??
