There are various methods used in experimental research in any topic or field that affects the people in the world we live in, and also in projects and research implementation and management. The methods used in a significantly large way determine the accuracy of the data collected the report that is issued at the end of the study and also the viability of the final findings.
In this assignment, we look at the single-factor two-level design. This is one of the designs of experiment (DoE) used in finding out and ascertaining the variability of any data collected from the field in any study, and for this reason therefore it id used as the method for hypothetical research study. The single factor two-level design has a number of advantages in that it is the simplest methods to use, and for this reason it comes in handy especially in complex research study. Secondly, it can be used in within subjects with repeated measures or in between subjects. When used in between subjects, it will take either independent or matched groups. This is particularly applicable when the subjects under scrutiny are variable. When used within subjects on the other hand, it is possible to test the hypothesis’ viability by carrying out the test either once using the Complete or Latin Square, or testing more than once using the Reverse or Block Randomization (Bordens & Abbott, 2008, p. 211).
The main disadvantage about the within subject design however is that testing the variables more than once especially in estimated variables, varying findings may result, thus undermining the viability of the tests. For this reason therefore, only one test should be carried out. From this analysis therefore, it is evident that within-subject design is an ideal way for hypothetical research study.
