00:00.000 --> 00:04.960
In this video we will discuss how to carry out your experiment and collect your raw data.

00:04.960 --> 00:10.960
We will talk about taking your time, filming your experiment, collecting more data than you need,

00:10.960 --> 00:16.080
putting your data straight into your raw data table and noting down any experimental issues.

00:16.880 --> 00:21.440
Please take your time so that you stay safe and that you don't need to repeat the experiment.

00:22.000 --> 00:25.840
Being in a hurry can obviously increase safety issues, and if you don't plan

00:25.840 --> 00:30.640
really enough time, you might have to set up your equipment again and repeat your experiment,

00:30.640 --> 00:36.400
which is annoying and a waste of time. Film your experiment so you can access your data later.

00:36.400 --> 00:41.200
This might be useful in case you lose your data or need to change the research question.

00:41.200 --> 00:45.440
If it doesn't make sense to film your data, for example in my experiment I am collecting

00:45.440 --> 00:50.160
frequency of sound, so I did not film the experiment, try to find a way to store your

00:50.160 --> 00:55.440
data outside your raw data table. Collecting more data than you need might help improve

00:55.440 --> 01:00.320
data quality in the future. If at some point you discover that you need a wider range or

01:00.320 --> 01:05.360
more trials, you can always come back and use some of this extra data. Put your data straight

01:05.360 --> 01:11.360
into your raw data table, because this saves time. In addition, this helps with not losing your data.

01:11.360 --> 01:16.240
As soon as you complete your table, save it online. Finally, note down any experimental

01:16.240 --> 01:21.360
issues, because this will be useful in your evaluation section. In your evaluation,

01:21.360 --> 01:26.960
you will write about errors in and improvements to your method. It will be much easier to remember

01:26.960 --> 01:32.240
these if you note them down while they are fresh in your head. Your table should have a title,

01:32.240 --> 01:37.600
and all your dependent variable values should be given to the same number of decimal places

01:37.600 --> 01:41.840
as your uncertainty. In the case of my table, it's one decimal place.

01:42.480 --> 01:48.000
We have now completed step 4 action 2. Now you know how to carry out your experiment and collect

01:48.000 --> 01:55.120
your raw data. In the next video, we will discuss uncertainty values in your raw data table.
