Hypothesis

As the weekend approaches my productivity level declines

Overview of Project

Since I was tracking the device usage and how it affects my productivity, I was exploring one more hypothesis that whether my productivity level is anyhow related to the weekday / weekend approach.
Hence, I went ahead made a line graph to see the pattern. This is calculated on the basis of manual calculation wherein I have taken the average of the productivity for the day.

The data I have been collecting is as follows:

Date
Day
Productivity Level

Conclusion

After seeing my visualization I can say that my productivity does decline during the weekend. But as I observed, if my sunday is not productive, it affects my monday as well. Monday also shows either consistently low productivity or same as Sunday's productivity.
