00:00.000 --> 00:04.240
In this video we will discuss how to calculate the averages for your dependent variable.
00:04.880 --> 00:10.480
We will look at an example calculation, rounding, and how to display your results.
00:10.480 --> 00:14.080
This part of your IA will be marked under the analysis criterion.
00:15.120 --> 00:20.480
When calculating averages, we add the dependent variable values from our trials and divide a
00:20.480 --> 00:26.560
sum by the total number of trials. In my example calculation, I will work with these five numbers.
00:27.280 --> 00:32.160
Data processing is in subsection two under data collection and analysis.
00:32.160 --> 00:35.600
The first step of data processing is calculating averages.
00:36.400 --> 00:40.320
In my example calculation, I briefly explain what I am doing,
00:40.320 --> 00:43.280
show my calculation, and round the final answer.
00:44.000 --> 00:48.880
It is very important to round your average to the same number of decimal places
00:48.880 --> 00:51.200
as the values from your row data table.
00:52.080 --> 00:55.360
I will calculate the averages for all of these columns,
00:55.360 --> 01:00.080
but I will not show these calculations in my IA to keep the work on size.
01:00.960 --> 01:05.120
Finally, I display the average values in the process data table.
01:05.120 --> 01:10.480
The table has a title and headings include the symbol for the variable and the unit.
01:10.480 --> 01:12.960
The symbol is in italics, the unit is not.
01:14.000 --> 01:16.560
This completes step five, action one.
01:16.560 --> 01:20.320
Now you know how to calculate the averages for your dependent variable.
01:20.320 --> 01:26.640
In the next video, we will discuss how to calculate uncertainties for your dependent variable.
