Two Different Studies Assessing the Effectiveness of Two Different Types

Short Answer

Two different studies assessing the effectiveness of two different types of social work intervention in preventing psychiatric hospitalization are conducted in two different regions by two different teams of researchers.One study,conducted in a rural area,finds that the mean number of days hospitalized for 10 treated clients is 60,as compared to a mean of 80 for 10 untreated clients.But this difference is not statistically significant.The other study,conducted in an urban area,finds a statistically significant p<05 difference in which 48 percent of 1,000 treated clients received some hospitalization,as compared to 52 percent of 1,000 untreated clients.What can and cannot be inferred about the comparative effectiveness of the two interventions? Explain.Can we infer that one intervention appears to be more effective than the other? Why or why not?
