The Research Process …  Paper 2 Section B – Design an Experiment Note: The example Q is from the old syllabus exam, however they are nearly identical and will still help us learn 4 Marks 10 Marks  We are going to DO this experiment. From start to finish – You wil write a LAB REPORT Lets read the question What features of the experiment can be identify from the flavour text?... Note: The example Q is from the old syllabus exam, however they are nearly identical and will still  Your Experiment Lab Report will include: Research Question Aim IV/DV & Operationalised Hypothesis Method Participants/Sample (Age Range, Ethnicity/Race, Sex, Glasses/hearing aid…) Sampling technique (why did you choose this technique) Experimental design (Independent measures/repeated…) Materials (What materials did you need to do the experiment) Ethics – Which ethical guidelines did you follow – informed consent / deception / debrief… Procedure (step-by-step everything the participant does from the beginning of the experiment Results – Table displaying 2 levels of IV and and Average, one or two sentences describing the results, any participant comments Discussion/Conclusion – Explain what the data means/Interpret the data. What are the limitations of your experiment (Confounding variables/Participant variables  New concepts – Reliability (Connected to Standardisation)  A Quick new (ish) concept - Standardisation Controls make sure the levels of the IV represent what they are supposed to (the difference between them will create the intended situation – which ensures validity – we have what we claim we have (measure) It is ALSO important that every participant is treated EXACTLY the same Why? The process of treating participants exactly the same is standardisation!!! Standardised instructions – everyone hears the same instructions Use the same equipment to measure responses Make sure each participiant stays in the procedure for the same amount of time How can you apply this to OUR experiment Controls & Standardisation overlap as concepts, but they ARE different! Standardising the procedure makes it more RELIABLE The extent to which a procedure task or measure is Why do we want consistent e.g. It this as will produce the psychologists? same results each time  Reliability Reliability in psychology is the consistency of the findings or results of a psychology research study. If findings or results remain the same or similar over multiple attempts, a researcher often considers it reliable. Reliability is important because it determines the value of a psychological test or study. If test results remain consistent when researchers conduct a study, its reliability ensures value to the field of psychology and other areas in which Your Experiment Lab Report will include: Research Question Aim IV/DV & Operationalised Hypothesis Method Participants/Sample (Age Range, Ethnicity/Race, Sex, Glasses/hearing aid…) Sampling technique (why did you choose this technique) Experimental design (Independent measures/repeated…) Materials (What materials did you need to do the experiment) Ethics – Which ethical guidelines did you follow – informed consent / deception / debrief… Procedure (step-by-step everything the participant does from the beginning of the experiment Results – Table displaying 2 levels of IV and and Average, one or two sentences describing the results, any participant comments Discussion/Conclusion – Explain what the data means/Interpret the data.
