WebCorrelation means there is a relationship or pattern between the values of two variables. A scatterplot displays data about two variables as a set of points in the xy xy -plane and is a useful tool for determining if there is a correlation between the variables. Causation means that one event causes another event to occur. WebRandomization is important for experimental design of proteomics experiments. First, the samples should be randomly selected from the population, so that the inference using the sample data can be generalized to the population. More importantly, the use of randomization can avoid bias caused by potentially unknown systematic errors.
