Focus groups vs. surveys In this section, we'll compare and contrast focus groups and surveys. We'll proceed to define both of them and then we'll describe and analyse their differences in social research. A focus group is a small group of between six and ten people who express their view about a particular topic that has been tightly defined by the researcher, who acts as a moderator (Gilbert and Stoneman, 2016). Surveys, on the other hand, use questionnaires to collect information that then will be codified. Surveys can be asked by the interviewer or they can be self-administered either by post or online (Babbie, 2013). First, let's compare internal validity. In surveys, it is easier to determine the internal validity of an indicator. You …show more content…

All the studies were carried out with the purpose of identifying the reasons for the increase of sexually transmitted infections (STI) and teen pregnancy. For focus groups, we selected two research articles on the topic (Roberts et al., 2005; Bay-Cheng et al., 2011). In one of the articles, the groups consisted of 43 girls from 14 to 17 years that formed seven focus groups. In the second article, there were four focus groups, with eight females and eight males from 15 to 17 in total. Both works selected agreed that because it was a sensitive topic, focus groups were ideal because of the less directive role of the researcher and the similarity between the participants made it easier to share their opinions and feel mutual support. None of the researchers used a random sampling selection technique; one advertised in a local newspaper while the other selected two schools and then selected students based on their communications skills, listening skills and interest in health-promotion activities. This translates in the studies not being generalizable as they can only represent the sample of people interviewed, especially in the second case where the participants all came from the same two schools. This also represents biased results, which harms its external validity. In the second article, the schools chosen were centrally located …show more content…

They administered a survey before and after the intervention. The total of students in that grade was 148 but only 95 (64%) had their parent's consent to participate, the intervention took place in a school in 'an economically and ethnically diverse' area. Participants were between the ages of 12 and 15. A correlation analysis was used to examine the relationship between the variables collected (gender ideology and sexual knowledge and contraceptive beliefs) for boys and girls separately. Similarly to our previous example, this research couldn't be generalized as the sample wasn't randomly selected and isn't representative of the population. The sample is biased seeing that only students with their parent's consent were allowed to take part. Nonetheless, since the students were interviewed before and after the intervention, changes resulting from the second survey can be regarded as occasioned by this intervention. This proves causality and therefore is an indicator of internal
