math studies is the most ironically named class I have ever taken because it barely involves math and nobody studies
They were probably thinking Oh, cool! I get to teach the smart kids! They’ll hand in all their work early!
And instead they get us.
In the case where you can choose your own topic, pick something easy that you also enjoy doing. Especially for a case where experimentation is involved, try to eliminate as many extraneous variables as possible.
Make sure there is actually resources available for your topic. As awesome as you…
When I was first starting IB, my teachers showered me with tips on how to handle the stress of IB. I thought I’d pass on the ones that really helped keep me sane these past couple of months.
- Study daily.
You won’t have enough time to revisit each and every chapter when studying for the…
I honestly believe that this is a very detailed website that critically discusses the IA and how to set it up offering very critical tips and information. My IA is due this Thursday, and it has honestly helped me out quite a bit.
Have different standard deviations for each data point? Not a graphing whiz? Having trouble inserting your error bars? Look no further!
Ok so I’m using Microsoft Word 2007, but it should be fairly similar for all versions … Firstly you want to go to “Insert” > “Chart” and pick the kind of graph you want. I’m going to go with a scatter plot.
After you select your chart, (you can change the layout of the graph using “Quick Layout” like i did) a microsoft excel window will automatically open alongside word. This is the window in which you will enter your data in (x,y) format.
After entering in your data (i’ve picked random numbers as an example) you’re going to want to create your own row underneath all that, and enter in your standard deviation points (in relation to the x,y points entered above).
So for example, 4.5 is the standard deviation value that goes along with the point (0.7, 2.7), 6.3 is the standard deviation value that goes along with the point (1.8, 3.2) etc.
You’re screen should now look something like this:
Next you want to close the excel window and go back to your graph. Under “Layout”, select “Error Bars” and then “More Error Bar Options” under the drop down menu.
Then once the box pops up, you tick off the bubble that says “Custom Values” and then “Specify Value” Now your window should look something like this:
We’re almost done! Now this will lead you once again to the alongside excel sheet with a little box that says ‘Custom Error Bars’. Use your cursor to highlight that entire row of standard deviations that we entered in earlier. Then hit “Ok”
Close your excel sheet and ta da! Error bars have appeared on your graph. You can now delete the horizontal ones if you do not want them, or the vertical ones by clicking and hitting “Delete” on your keyboard… Your graph will end up looking something like this:
Voila! You’re now an error bar pro! Happy lab writing :)
