1-Those data collection tools are valid scientific tools because it's have been done by scientist so that means they have done those experiments to many people and figured out the information they presented.

2- I think if I do the online survey again I would have the same results because two of my friends have done twice and they had a slight different between both results. Furthermore, online survey are always right because they're using kind of technology that rarely have mistakes or errors.

3-I think the online survey would be better choice to do with a large group of people because as I mentioned before this kind of technology once in the blue moon have mistakes. So that means they will have more realistic results and more right.

I've changed my idea about one statement which is women are better listeners than are men because of several reasons.First of all, after having some statistics and see some lecture I found out that women are better listener. According to an experiment has been done by Cardinal where he asked a group of sex people included 3 men and 3 women to pretend that they're interviewer and while they're talking they'll be asked to do something else. For example, one of the participants were asked to drink water while she was interviewing. The results for this experiment were all women did it right. On the other hand, one out of three men did it right. Secondly, I tried to look at the females in our class since we started this unite and I figured out that they take more notes than males do. Sometimes those notes are more than what we need but the point is they can listen and write at the same time and bigger amount than us.

Happiness can be defined as a feel which is opposite of sadness. I feel happy with several things and in several times. Firstly, I love the feeling when I finish doing my homework and be free the rest of the day and that's makes me happy. Another one is when I smoke shesha after eating a heavy meal. This one only the smokers can understand what I mean. In addition, I feel happy when I see my parents happy and proud of me. Most importantly, I feel happy when I pray at the exact time that the pray have to be done. As an advice for other people that might makes them happy is to be optimistic always and don't feel about something that already happened. For instance, if someone failed the exam he or she has to think about the future and how to do better in other exams. My level of happiness has changed since I moved to Canada because I started to feel what my parents think about and the way they act with me. For example, once when I graduated from my school in Vancouver my parents were so proud of me and happy for me too. They told me to ask for whatever I want and they send me money to travel somewhere and have fun. This is kind of happiness for me. There are several secrets of happiness but what i believe in is to trust yourself and being optimistic always.
