What does the sample size (n=) mean for this analysis

+ Automatic Zoom
The efficacy of two kinds of cognitive-behavioral therapy (CBT) in relation to a clinical population were
compared. The therapies differed on the dimension of how wedded they were to the rational-emotive
behavioral therapy (REBT), a subtype of CBT that emphasizes a directive, confrontational approach to
encourage a patient to recognize the irrationality of specific thought patterns. Forty adolescents at an
inpatient clinic for treatment of self-destructive behaviors were randomly divided into two groups of
equal size, one of which received the less challenging type of CBT (Treatment A) and one of which
received the more challenging kind of CBT (Treatment B). All patients were treated by trained therapists
in one-on-one sessions for 1.5 hours per day (broken down into 45-minute sessions) for six weeks. All
participants were apprised that they were part of a study, all participants signed consent forms, and all
were told they would be informed of the results at its conclusion; participants exhibiting any behaviors
that required critical intervention were promptly treated outside the plan of the study. Outcome data
on the Revised Behavior Problem Checklist (RBPC)-PAR Edition* collected at the conclusion of six weeks
as shown below (also found in the Data Set Scenario 3 Excel file).

Definition Definition Number of subjects or observations included in a study. A large sample size typically provides more reliable results and better representation of the population. As sample size and width of confidence interval are inversely related, if the sample size is increased, the width of the confidence interval decreases.
