![]() ![]() From the graph, it can be inferred that as one variable increases, the other decreases this is evident as the data points direct downwards. The graph below shows a negative correlation. The graph can be interpreted as a positive correlation that indicates that as time spent studying increases, the test scores students receive also increases.įigure 1: The scatterplot infers a positive correlation between time spent studying and test scores. ![]() From the graph, it can be inferred that one co-variable would increase as the other co-variable increases this is evident as the data points direct upwards. The graph below shows a positive correlation. The following data used and shown are completely hypothetical and StudySmarter Originals. To finish, we will evaluate correlational research, including the advantages of correlation in psychology and its disadvantages.Ĭorrelations are a standard statistical test used in psychology.We will start by looking at the correlation meaning, correlation formula and the different types of correlation.Let's take a look at correlational research in psychology.Let's take a look at how correlations are studied in psychology. We expect to find a positive correlation between the variables. Or, the researcher may measure how much participants sweated on a hot day. If the hot day scenario was to be tested, a researcher might record the temperature changes and how much the participant sweats. For example, the co-variable 'a hot day' will be positively correlated with 'sweating a lot' it is hot today so I will sweat a lot. We may even state something in our everyday life, which is a predictive correlation. During your time studying research methods, correlations are something that will come up frequently. ![]()
