In this video we will discuss how to calculate the averages for your dependent variable.
We will look at an example calculation, rounding, and how to display your results.
This part of your IA will be marked under the analysis criterion.
When calculating averages, we add the dependent variable values from our trials and divide a
sum by the total number of trials. In my example calculation, I will work with these five numbers.
Data processing is in subsection two under data collection and analysis.
The first step of data processing is calculating averages.
In my example calculation, I briefly explain what I am doing,
show my calculation, and round the final answer.
It is very important to round your average to the same number of decimal places
as the values from your row data table.
I will calculate the averages for all of these columns,
but I will not show these calculations in my IA to keep the work on size.
Finally, I display the average values in the process data table.
The table has a title and headings include the symbol for the variable and the unit.
The symbol is in italics, the unit is not.
This completes step five, action one.
Now you know how to calculate the averages for your dependent variable.
In the next video, we will discuss how to calculate uncertainties for your dependent variable.
