1,2,3. I have chosen an article called “The Effectiveness of Short Message Service for Communication With
Concerns of Privacy Protection and Conflict Avoidance” from “Journal of
Computer-Mediated Communication”. I happen to be the same journal as last week
so the impact factor is still 1.778 and 5-year is 4.748.
The title of the article caught my interest since my personal communication methods have changed quite a lot with the introduction of free SMS and other messaging services.

In this paper had a cross-sectional research design where
they conducted surveys out on the street face-to-face with the subjects. The
survey was conducted three times. The first one was a pilot study and was
conducted in April 2008 in Hong Kong (183 participants), an extensive survey in
Hong Kong August 2008 (558 participants) and a third extensive survey in
October 2008 in Shanghai (210 participants). In total 953 valid responses were
recorded and 31 were void. Those who finished the survey received a small gift
as a token of appreciation.
The strengths of conducting a survey on the street are that it has a larger potential reach who answers the questions (different ages, job nature and education level) thus making it more representative, and according to the paper this kind of study will keep the response rate higher. However the response rates were 10% in Hong Kong and 8% in Shanghai, which seems low to me but they might have been lower if he survey was conducted online.
A weakness of the study is that all measurement items were collected at the same point of time. If they conducted a longitudinal study they might have been able to make predictions about the future.
They were able to see patterns in how people preferred using SMS in certain situations e.g. to avoid conflict. The researchers speculate upon what kind of conflict they’re avoiding when sending a SMS and their speculations seems probable to me but this is a weakness when conducting quantitative studies. It’s easy to see patterns but you might need more specific information to really understand the result.
If the study was conducted online or sent to the participants by mail it would have been possible to conduct a longitudinal study which would have improved the quality of the study.

I
also read “Physical activity, stress, and self-reported upper respiratory tract
infection” by Fondell et al.
In this paper they were interested in the relationship between physical activity levels, perceived stress and incidence of self-reported upper respiratory tract infection. A cohort study was conducted on 1509 participants in the age between 20-60 years during a 4-month period with five follow up questionnaires. They reached 74% of the total participants. The study was conducted online.

4. Quantitative
methods are great since its possible to have a large sample size. The variables
are easily measured when the participants answer quantifiable questions with
numbers. Even though the method provides a lot of data, the data it provides can be used to recognize patterns but not always more then that.
5. Qualitative methods are better used when the answers to the questions cant be quantifiable. The sample sizes are usually smaller but can provide more detailed information and is therefore great to conduct after a quantitative study has been conducted to be able to understand the patterns better. Due to the answers being more extensive and needs more analyzing the sample sizes usually are smaller.
