Can anyone please tell me how to draw a standard deviation graph in the biology 3B may2012 question 1b(ii)

Okay, the standard deviation for the first point is 0.09!
So you add 0.09 to that point ( in this case 4.1) and draw a small horizontal line, then you go down 0.09 ( from 4.1) and draw another horizontal line.

Hello! I was just hoping somebody could clear this up for me. Can i break graphs in 3B? And start a graph from a number other than zero? because i've come across this really weird graph and i have no idea what to do about it.:confused:

Yes you can break graphs.

How can I plot standard deviation in a graph?I can plot the graph knowing the independant and dependant variables but I have no idea how to plot SD.This came in many of the recent papers for e.g Jan13 Q1b(i)and Jan12 Q1b(ii).Please explain using any example as soon as possible,my exam is tomorrow!

Dont worryy it's very simple
All you need to do, is add and subtract the SD from your point
FOR EXAMPLE, if your point is 345 and SD is 8 .. you add 8 and then draw a little horizontal line .. then subtract 8 and draw another horizontal line
Like this picture that only shows bar graph but the point is to see the horizontal line images.jpg

That sounds far fetched IMO.
For biology they have coursework instead of practicals ryt? Unlike chem n phy.

Most likely to be topics from Unit 1, ex, CVD..
I recommend you just skimming through the unit 1 syllabus

it means standard deviations overlap. when they overlap, the data is said to be less reliable. Say you had SD's of 4 and 6 those overlap (PS: they can never go that high) the data is not reliable, even if SD's are given
Another problem in Bibliography in jan 2012, any body pleaseee help me heree! tell me the exact answer for both and explain for me too! thankss!

Jiang, Dennis is the author where Dennis is his first name and Jiang is the second. The correct answer to the question is Jiang, Dennis, 2008, "The Stem Cells That Promise No Miracles", the Journal of Young Investigators,18 (3)

as to the second question, what u have written is wrong. U can write that the student can give a reference to the Kew paper.

Yes,I get it.So,after drawing the two horizontal lines, we draw a vertical line on the centre of the two horizontal lines,right?Can youl please show the graph with SD from Jan12 Q1b(ii).It would be really helpful,thanks.

Kew Ref is there in the 3rd paragraph

And they mean it was quoted in "Jiang, Dennis....." something like that.

The date thing i'm not sure but yeah better to write "18 (3) 2008" at the end of the bibliography
