The experimental method is a procedure carried out to support or reject a hypothesis. The mean is calculated by adding all the numbers in a set together and dividing the total by the number of numbers. Experimental and clinical psychologists conduct research in psychology to better understand human thought and behavior. There are several different types of inferential test in addition to the sign test. In a repeated measures design (within groups), a group of participants are recruited, and the group does the experimental task with the IV set for condition 1 and then the same for condition 2. After describing A level psychology video resource - in this video I cover Experimental method. For example, IS = interacted with stranger, and AS = avoided stranger. consistently) record a persons height as 200m, but that doesnt mean this measurement is accurate. which two variables are For example, the average number of limbs for a human being will have a, Easy and quick to calculate: You just subtract one number from another, Accounts for freak scores (highest and lowest). Many characteristics e.g. A scattergram illustrates two variables for various data points. Participants behaviour is distorted as they fear being judged by observers, A target behaviour is identified and the observer records it every time it occurs, The group that received the experimental treatment (e.g. a theory go on to describe a piece of research evidence saying, Xs study Contextualising how the topic in question relates to That SSRIs have no effect on symptoms on depression or subject conformity will be the same when orders are issued by someone wearing a uniform as when orders are issued by someone bot wearing a uniform.

Case studies are in-depth investigations of a single person, group, event or community. It cant be counted but can be turned into quantitative data by placing the data in categories and then counting frequency. The researcher decides where the experiment will take place, at what time, with which participants, in what circumstances and using a standardized procedure. There are no set questions and the participant is given the opportunity to raise whatever topics he/she feels are relevant and ask them in their own way. This method means each member of the population has an equal chance of being selected and thus is not subject to any bias. Data from studies can be quantitative or qualitative: For example, some quantitative data in the Milgram experiment would be how many subjects delivered a lethal shock. develop and refine practical design and procedures. In a repeated measures experiment, researchers may use counterbalancing to control for the order in which tasks are completed. A sampling technique where participants are chosen because they are easily available, Order effects can occur in a repeated measures design and refers to how the positioning of tasks influences the outcome e.g. They generate qualitative data. We must use operationalisation to ensure that variables are in a form that can be easily tested e.g. advertisements, books films etc.). by deliberately giving wrong answers). The peer reviewers assess: the methods and designs used, originality of the findings, the validity of the original research findings and its content, structure and language. The x-axis lists the categories and the y-axis illustrates the different results between the categories.
