I need to respond to the following statement
There are similarities and differences between mean differences and simple regression. A similarity between them is that they both show the difference between 2 or more variables. A difference between them is simple regression is used to show the relationship of continuous variables while mean difference shows a constant. The mean difference is Unaffected by the order in which the variables are used. Simple regression tends to use a constant variable to find the answers to the variable in which you are intending for, without the constant variable you cannot find the correct result.
