A group of individuals may be asked to shelve their individual weights together with the number of hours they sleep in a day Correlation can then provide a specific load value whether weight and sleep dummy are related to each otherOne more type of statistical analysis process is regression Regression aims to evidence a particular approach to observe the trends followed by a set of data .
