onsider the following scenario about clinical research. Two researchers decide to address an important question concerning a particular approach to language intervention. The researchers have a good theoretical foundation for the particular intervention procedure. They suspect that the intervention approach will result in more functional language use for children. Given that the methods and design of the research are sound, they try to determine which of two possible outcomes may be true in the real world. One possibility is the null hypothesis: The language intervention procedure will not make a difference in developing (or hindering) the specific language behaviors. The alternate hypothesis is that the intervention will make a difference. The researchers must also determine whether the data obtained in the study reflect a “real” difference and not one that would occur by chance, given their hypothesis; thus, they establish a predetermined degree of certainty, typically, an alpha level = .05. Ultimately, their findings are submitted for publication, peer reviewed, and accepted for publication. Clinicians read the article and attempt to make the link from research to practice. Questions that clinicians might ask about the findings are: “What is the practical significance of this study?” or “How confident can we be that the approach is likely to make a real difference with the individual children we see?”
