Excel Graphing Screencasts
These two videos are for my classes, made using the free screencast tool ScreenCast-O-Matic.
The first is for my IB Bio group for setting up a graph for a complex set of data, adding extra datasets, error bars and formatting. The second is a similar video for a simple Physics investigation in Grade 10.
Hopefully they are helpful as you can go back and re-watch important bits as you do the write-ups.
If anyone knows of a decent way to add best-fit curves (lines are easy) to datasets, please let me know!

Linked to some of the other posts about data visualisations, here is Information is Beautiful creator David McCandless at TED Global 2010.
“Data is the new (s)oil”
Visualisation is a great tool for highlighting trends and patterns in data sets, but we must still learn to go into the data ourselves. We must use a critical eye when looking at these graphics – what do they intend to communicate and how well do they achieve their goal?
Not a video, but…
… a great site for visualising data. InformationIsBeautiful.net.
I particularly like these posts:
