Content: Once the desired conditions have been created, the studies measure the effects of them. For its part, in non-experimental investigations this manipulation does not exist, but rather the data is collected directly in the environment in which the events take place. It can not be said that one method is better than the other. Each one is equally valid depending on what is going to be studied and / or on the perspective that the researcher wants to give to his work. By its own characteristics, if the research is experimental it will be much easier to repeat it to ensure the results. However, the control of the environment makes some variables that may appear spontaneously more difficult to measure. It is just the opposite of what happens with non-experimental designs. characteristics
As previously mentioned, the first characteristic of this type of research is that there is no manipulation of the variables studied. Normally, these are phenomena that have already occurred and are analyzed a posteriori. Apart from this characteristic, other peculiarities present in these designs can be pointed out:
