The type of research method used forthis experiment is a field experiment.
This kind of experiment will usuallytake place in a natural setting such as a class room. This helps create a morenatural everyday environment The advantages of afield experiment are that they can provide better ecological validity. This isdue to them being carried out in natural settings. A field experiment can alsobe carried out in large organisations and areas where there are many people. The Disadvantages of afield experiment are extraneous variables these can not be accounted for in anexperiment and can influence researched to bias conclusions.
The participantsmay also respond differently as they know that they are part of an experiment.The type of samplingmethod used in this research is opportunity sampling. For this research,opportunity sampling was chosen as the sample of participants used were takenfrom people who were available at the time the study took place. A strength ofopportunity sampling is that the sample is readily available therefore makingit cheap, quick, and easy to carry out. Disadvantage is that the researcher’sown bias towards the participants such as age or appearance prevent them fromparticipating. Another sampling methodthat could be used is random sampling a strength of random sampling is all theparticipants have a chance at being randomly selected.
This removes bias fromthe experimenter. A disadvantage is that it can be rather time consuming as youneed a list of the whole target population. When conducting thisresearch, the experimenter would have to take in to account the participantsright to withdraw.
This is because it is common in field experiments forparticipants to be unaware they are part of an experiment, thus are unable towithdraw from the experiment.Class 1Results- 7, 8, 8, 8, 10, 10, 11, 11, 12, 15Mean= 8 + 10 + 11 + 8 + 8 + 15 + 12 + 7 + 11 + 10 = 100 ÷ 10= 10Median= 10Mode= 8 Class 2Results- 8, 9, 11, 12, 12, 12, 15, 15, 18, 18Mean= 8 + 9 + 11 + 12 + 12 + 12 + 15 + 15 + 18 + 18 = 130 ÷10 = 13Median= 12 Semi-structured interviews are a formof structured interview in which pre-set questions are used, althoughspontaneous questions can be asked to give extra clarity on certain areas. Thistype of non-experimental research is beneficial for this kind study as itallows the researcher to use a combination of both pre-set questions as well asspontaneous questions to gain better ecological and qualitative research data.
However, a strength is that the researcher can clarify any answers to certainquestions while still keeping control of the interview. A weakness of this typeof interview is that the participants who are taking part my give theresearcher the answers that they want to hear.
