A clinician interested in agoraphobia (fear of public places) tests a new treatment method. She samples five agoraphobics from her clinic and has them report how many times they ventured out of their houses (on their own) in the past month. They then received relaxation training and were introduced to trips away from their homes at gradually increasing durations. After 2 months, subjects again reported how many times they ventured (on their own) out of their houses. The data are below. Assess whether there is a significant change in trips outside the home from before to after therapy. a. Report and interpret an effect size b. what type of error might you be making?

Question
  1. A clinician interested in agoraphobia (fear of public places) tests a new treatment method. She samples five agoraphobics from her clinic and has them report how many times they ventured out of their houses (on their own) in the past month. They then received relaxation training and were introduced to trips away from their homes at gradually increasing durations. After 2 months, subjects again reported how many times they ventured (on their own) out of their houses. The data are below. Assess whether there is a significant change in trips outside the home from before to after therapy.

a. Report and interpret an effect size

b. what type of error might you be making?

**Data Table of Subject Trips Before and After**

This table provides data on five subjects, detailing the number of trips taken before and after a specific event or intervention.

- **Columns:**
  - The first column lists each subject, numbered from 1 to 5.
  - The second column, "Trips before," shows the number of trips each subject took prior to a certain event.
  - The third column, "Trips after," displays the number of trips taken by each subject after the event.

- **Data:**

  - **Subject 1:** 
    - Trips before: 0
    - Trips after: 2
  
  - **Subject 2:** 
    - Trips before: 0
    - Trips after: 2
  
  - **Subject 3:** 
    - Trips before: 3
    - Trips after: 4
  
  - **Subject 4:** 
    - Trips before: 3
    - Trips after: 7
  
  - **Subject 5:** 
    - Trips before: 2
    - Trips after: 6

This table can be used to analyze the change in the number of trips taken by each subject after intervention, helping to measure its impact or effectiveness.
