Question

Not all EBP projects result in statistically significant results. Define clinical significance, and explain the difference between clinical and statistical significance. How can you use clinical significance to support positive outcomes in your project?

Answer 1

Statistically significant results

Statistical significance has to do with the likelihood that a research result is true(i.e., a real effect of the intervention) and not merely a matter of chance.

Clinical significance

Clinical significance is sometimes called clinical importance or practical importance. I don't think I've ever observed an "authority" or best quality level meaning of clinical importance in light of the fact that the criteria will change contingent upon the sickness, condition, or patient populace.

The difference between clinical and statistical significance

Statistical significance and clinical significance. They are not the same thing. One answers the question, Are the statistical results due to random chance? and the other answers the question, So what? Will the results matter to our patients?

Significance means “the quality of being important.” Importance is a value judgment, right? In spite of the fact that esteem judgments are viewed as emotional, there are components of the "thing" being valued that assistance one appoint the normal for criticalness. In research, we attribute importance or worth to research findings according to accepted, albeit sometimes arbitrary, conventions.

Significant, in terms of statistics, is defined as “probably caused by something other than mere chance.” Researchers proclaim a study finding to be “statistically significant” or not, depending on whether their research result is less than the a priori alpha level set before the study commenced.

Clinical significance to support positive outcomes

Short break before we go on to clarify some commonly misunderstood points. I'm marking these harder or confounded research ideas as research staying focuses. Here are a few related to our topic.

Research Sticking Point 1: Many students don’t quite get how researchers determine whether their research results are statistically significant or not. Basically, the researchers conduct their experiment and enter their data into a statistical program, like IBM’s SPSS Statistics. When they are fulfilled that the information entered is finished and precise, they run the measurable tests required to answer their exploration speculations (e.g., Chi-square, connection, ANOVA). They then compare the p-value they get from their test results to their a priori alpha level. If the p-value is less than their alpha level (i.e., p < 0.05) then they declare their result statistically significant. If the resulting p-value is greater than the alpha level, the result is not statistically significant.

Research Sticking Point 2: The invalid speculation is constantly thought to be valid. In many investigations, the analyst is endeavoring to dismiss or negate the invalid speculation that their factors of premium have no relationship or are the same than the SOC (H0 = H1)). By dismissing or invalidating the invalid, they can acknowledge the elective theory (H1 ≠ H0) and proclaim their variable is measurably critical.
