Strengths Of Lab Experiments. It provides researchers with a high level of control. It is known which variables are exogenous and which are endogenous allows to make causal inferences. Firstly the controlled environment means it easy to replicate the exact environmental conditions of the original experiment and this also means it is relatively easy for the researcher to clearly outline the exact stages of the experiment again making exact replication easier. A large number of studies have been performed by Qi and his co-authors 18 20.
Strengths And Weaknesses Of Field And Laboratory Experiments Download Table From researchgate.net
The components required pertaining to the experiment should be collected from Lab- in-charge after duly filling in the requisition form. Results show that the elastic modulus yield stress and tensile strength decrease with increasing temperature. There is no limit to the subject matter or industry involved. An experimenter must ensure that their experimental design is fair in order to be sure that the results and conclusions collected and formed are valid. It provides researchers with a high level of control. STRENGTH OF MATERIALS LAB MANUAL Academic Year.
You can precisely measure the exact effect of one thing on another.

In general because of the controls put in place the level of reliability is relatively high for laboratory experiments. However it must also be noted that it is not possible to completely control all variables. Standardised procedures and instructions are used which enables researchers to repeat the study in the exact same way with other participants. Page 9 10. Evaluation of laboratory experiments.
