This week, we analyzed the results and made some conclusions. First and foremost, we cannot prove anything due to our statistically insignificant results. However, we can state that our results have a general trend of smartphone usage decreasing both stress and efficiency. A possible reason for smartphones decreasing stress is the fact that, like many addictive processes, rewarding neurotransmitters are released after usage. A possible reason for smartphones decreasing productivity is the fact that an optimal amount of stress and arousal is needed to achieve peak efficiency. Yet, smartphone use may lead to someone having less than peak levels of stress and arousal, thus not performing optimally. We have also found that our study has some sources of error: equipment unreliability, it being a convenience sample (most of the students were boarders- there might be a lurking variable in boarding life or being from a different culture that may have affected the results), and students in the control group oftentimes talking to students around them. It seems that although our data is not statistically significant, our data's trend suggests that students may be better off not using smartphones before doing academic work due to their increased efficiency. Likewise, if students are feeling overwhelmed due to stress, they may benefit from using their smartphones a little bit.
Here are my daily tasks for next week:
In class, we will write the script and collect documentation for our presentation
We will rehearse our presentation
We will conduct more statistical analysis (ex. without outliers)
