1. Do you think these data collection tools are valid scientific tools? Why or Why not? (In research this is part of what is called validity)

I think these data collection tools are not valid because when peaople answer the survey , noone take it serious. Therefore, the answers could be elusory.My second reason is that, if the questions are intended for feelings or behaviour, most of people play role of someone who they want to be.Hovewer, these tools could be valid but how much valid ?

2. Do you think your results would be if you took the on-line questionnaire at a different time, on a different day? Why or why not? (In research this is part of what is called reliability)

(I will reply these questions as i believe that tools are valid )I dont think results can vary according to time because the feelings about some specific and special things like feelings about our life, or sentiments don`t change. Even if some events around us change and these events influence us, the basic answers can`t vary. Due to the fact that questions prepare upon specific points.

3. Which of the two tools is better to do with a large group of people (eg. university students, people living in cities versus rural locations, etc.) to discover patterns of happiness in a given population? Why do you think that one is better suited?

If the researchers ask for the realistic answers, they have to do with everybody. I can`t say to do with university students is logically because they have a lot of desire , they have a lot of idea, they are sometimes dreamer .They can sometimes be realistic but they are young and they know the world or the meaning of the feelings according to their experience but those experience are not enough. However , there is one expression "Four eyes see more than two"
