NOTE: THIS SURVEY HAS BEEN COMPLETED, I NO LONGER NEED HELP!
AND THANK YOU ALL FOR FILLING THE SURVEY!
Greetings, humans. I am making a survey of caffeine's effects on tiredness. If you could find it in yourself to take a moment to answer the following questions, it would be greatly appreciated. I will post the results (statistics) in this thread when I'm ready.
1. On average how many litres per week do you drink energy drinks?
2. On average how many litres per week do you drink coffee? (One cup ~ 0.2 litres)
3. On average how many litres per week do you drink tea and soda?
4. On average how many hours per week do you sleep?
5. On average how tired do you feel on a scale from 1 to 10. (Brisk -> Tired)
6. (If you answered over 5 on last question) What do you think is the reason for your tiredness?
And here is how to answer:
Thank you for you co-operation!
Here, have some pineapple!
Results
--Statistics:
71 people filled this survey
The average amount of energy drinks per week was 2.8dl (1dl = 0.1l)
The average amount of coffee per week was 13.8dl (1dl = 0.1l)
The average amount of tea and soda per week was 33dl (1dl = 0.1l)
The average amount of sleep per week was 49.4
The average tiredness level was 5.2
--Conclusions:
Tiredness is affected by so many factors, that higher consumption of cafeine is rarely the (only) reason behind it. People who consumed more cafeine were not more or less tired than those who had less cafeine. Here is a chart with dots in it:
What I found interesting, however, was that the people who sleep less were not generally any more tired than those who sleep more. I'd guess the reason behind this is that people are different: some people just make do with less sleep than others. Here are some more dots in a chart:
Thank you again for helping with the survey.
