In this video we will discuss how to carry out your experiment and collect your raw data.
We will talk about taking your time, filming your experiment, collecting more data than you need,
putting your data straight into your raw data table and noting down any experimental issues.
Please take your time so that you stay safe and that you don't need to repeat the experiment.
Being in a hurry can obviously increase safety issues, and if you don't plan
really enough time, you might have to set up your equipment again and repeat your experiment,
which is annoying and a waste of time. Film your experiment so you can access your data later.
This might be useful in case you lose your data or need to change the research question.
If it doesn't make sense to film your data, for example in my experiment I am collecting
frequency of sound, so I did not film the experiment, try to find a way to store your
data outside your raw data table. Collecting more data than you need might help improve
data quality in the future. If at some point you discover that you need a wider range or
more trials, you can always come back and use some of this extra data. Put your data straight
into your raw data table, because this saves time. In addition, this helps with not losing your data.
As soon as you complete your table, save it online. Finally, note down any experimental
issues, because this will be useful in your evaluation section. In your evaluation,
you will write about errors in and improvements to your method. It will be much easier to remember
these if you note them down while they are fresh in your head. Your table should have a title,
and all your dependent variable values should be given to the same number of decimal places
as your uncertainty. In the case of my table, it's one decimal place.
We have now completed step 4 action 2. Now you know how to carry out your experiment and collect
your raw data. In the next video, we will discuss uncertainty values in your raw data table.
