What is the difference between statistically and clinically significant research

Expert Solution

A statistically significance in research is the relationship between 2 or more variables and its effects.A p - value of 5 % or lower is considered as statistical significant research study and if the p - value is large the research study is statistically insignificant. Statistical significance in research provides evidence about the plausibility of null hypothesis ,which hypothesizes that there is nothing more than random chance at work in data. Statistical significance is the ability to state that the observed difference in an outcome is not due to chance alone. Statistically significance . research is necessary for clinical significance but says nothing about the magnitude of effect.

Clinically significant research means the findings of the study is useful with patients. Clinical significance in research is the probabilities of benefit and harm .A clinical significant difference is clinically relevant and thus merits subsequent action.

Large sample + large effect = statistically significant and clinical significant

Large sample + small effect = statistically significant ,may not be clinically significant.

Small sample + large effect = maybe clinical significant but does not show statistically significance.

A researcher is interested in understanding if there is a statistically significant difference between people in different marital status in terms of their level of general happiness. Marital status was measured as follows: 1. Married, 2. Widowed, 3. Divorced, 4. Separated, and 5. Never married. General happiness was measured as follows: 1. Very happy, 2. Pretty happy, and 3. Not too happy. To test his hypothesis, the researcher ran the Analysis of Variance (ANOVA), and he obtained the following output table. ANOVA...

Is there a statistically significant difference in weight between men and women? (Conduct an independent t test.) Identify the independent and dependent variables. Write a null hypothesis. Write an alternative non-directional (2-tail) hypothesis. Interpret your results. Guidelines for interpreting independent t tests can be found in What to Include When Writing Up Independent t Test Results (PDF).

.You are interested in determining whether there is a statistically significant difference between economics and political science majors in terms of their overall grade point average (GPA). You randomly sample 10 economics majors and 16 political science majors. You find that the average economist has a 3.0 GPA with a standard deviation of 0.4, and the average political scientist has a 3.4 GPA with a standard deviation of 0.3. Conduct a two-tailed hypothesis test using significance level α = 0.05....
