Which of the following isn't an aspect to be considered when planning your problem question?
You’ll need to analyze data. You can’t just report about data other people have collected.
If you’re doing a controlled experiment - you’ll need at least 5 levels of your manipulated variable and 5 trials at each of those levels. If possible, 10 trials is better.
If you’re doing a correlation study - you’ll need at least 30-100 data points (depending on how easy data is to collect) in order to draw a conclusion.
If you’re doing an experiment with human subjects you’ll need to consider random sampling of individuals and report it in the Appendix section.
Which one isn't a reliable source to include in a background research section of an internal assessment report?
An article from "la Recherche" magazine
A paper published in the "Biotropica" journal
The unpublished results of a Master's thesis on your research subject by a student from Javeriana University.
An article from the Khan academy website
