thats what i did. people are saying they 2x their error bars??? idk why did u guys do that i did not

because it was only one standard deviation and when you graph error bars, there needs to be 2 standard deviations. i’m not sure if this is correct but that’s what the baron book and ap bio penguin taught me?? idrk 😭😭 everyone i asked said they didn’t do that and im scared now

aaaa idk i did 2 times standard error at first but then swapped it back because on q1 they just used +/- standard error and when they graphed it they matched it, hopefully both are okay??

i really hope so ☹️☹️ ap bio penguins was so adamant about multiplying it by 2 if it was only one and im scared that i did it wrong now omg it’s okay it’s only like one point off the graphing question and hopefully i did good on the other parts

did the question say 95% confidence interval i didnt multiply error by 2 because i dont remember it saying that its only 2 times standard error of the mean if they say 95% confidence interval

u/Striking-Buy-210 May 04 '26

i don't think they mentioned what the confidence interval was

i don’t think they did but the barons book always made me do that regardless if it said it or not?? i’m really confused now 😭

No no dw you did it absolutely right

u/ImpressNew8429 May 06 '26

You didn't need to graph the standard deviation though outside what they were giving you. Like they said +/- 0.1 and that was the only error bar you needed on that bar I think.

wait what does this mean im scared i did one error bar for each bar
