The circumstances and effect relationship to be

The views and opinions any researchers are assesed through various methods. These approaches are particularly important as they make collected data more valid and less biased. Lab experiment are conducted in a well controlled environment  and hence produce accurate measurements are possible. The experimenter  decides how, when and where the experiment will occur. They choose the  participants,  circumstances of the experiment. Participants should be randomly given to independent variable group. Lap experiments strengths include the fact that they are easier to replicate  because a standardized procedure is used.  Exact control of unessential and independent variables permits a circumstances and effect relationship to be shaped. In any case, it is a counterfeit setting and delivers unnatural behaviour that do not mirror real life and has low biological legitimacy making it hard to sum up the discoveries to a genuine setting. Results might be biased and progress toward becoming confounding variables due to the demand charecteristics or experimenter effects (Shadish,2002).According to Ahmed and Akbar (2009) field experiments are carried out  in the everyday or real life environment of the participants. The experimenter however can manipulate the independent variable, but  have little or no control of extraneous variables, and no random allocation of participants.Its strengths incorporates of the behaviour in a field experiment  will probably reflect real life situations  in light of its natural setting which has higher environmental legitimacy than a lab test. As indicated by Dunning and Thad (2012) there is likewise less odds of demand characteristics  influencing the results, as participants may not know they are being studied and this happens when the investigation is undercover. There is nonetheless, less control over incidental factors that may predisposition the outcomes and this makes it troublesome for another researcher to reproduce the investigation in the very same way. There is additionally ethical ramifications of misdirection of participants .Case studies are deep investigations of an individual or group and data is gathered from various  sources through different techniques like observations and interviews. Due to the top to bottom approach of case studies they give insights on aspects of human thinking and behaviour that would be unethical to examine in different ways. They are utilized as a part of exploratory research and aides in generation of new thoughts and are an imperative method for representing theories and can help indicate how unique parts of a person’s life are identified with each other (Jeremy and Teigen, 2014). A strength of case study is that it gives point by point and subjective data and likewise gives knowledge to additionally research. However case studies, generalise the results to apply to a more extensive populace. Diffucult to reproduce and tedious in light of the fact that a case studies manages just a single individual/occasion/aggregate one can never make sure whether the decisions made from a specific case apply somewhere else. The consequences of the examination are not generalizable on the grounds that we can never know whether the case we have explored is illustrative of the more extensive group of comparable cases (Jeremy and Teigen, 2014
