A researcher would like to evaluate the effectiveness of a pain-relief patch designed for lower back pain. Prior to testing the patch, each of n = 8 patients rates the current level of back pain on a scale from 1 to 10. After wearing the patch for 90 minutes, a second pain rating is recorded. The data are as follows: Include in your responses:K. Use mathematical notation to present the resultsL. Compute Cohen’s d to measure the size of the effect.M. Write a concise conclusion statement that includes the results of the study and the effect size. **Data Table: Before and After Analysis**This table presents a side-by-side comparison of two sets of numerical values, labeled "Before" and "After."

Question

A researcher would like to evaluate the effectiveness of a pain-relief patch designed for lower back pain. Prior to testing the patch, each of n = 8 patients rates the current level of back pain on a scale from 1 to 10. After wearing the patch for 90 minutes, a second pain rating is recorded. The data are as follows: Include in your responses:

K. Use mathematical notation to present the results

L. Compute Cohen’s d to measure the size of the effect.

M. Write a concise conclusion statement that includes the results of the study and the effect size.

**Data Table: Before and After Analysis**

This table presents a side-by-side comparison of two sets of numerical values, labeled "Before" and "After." It consists of the following entries:

- Before: 6, After: 2
- Before: 8, After: 3
- Before: 9, After: 4
- Before: 8, After: 1
- Before: 10, After: 2
- Before: 5, After: 3
- Before: 9, After: 8
- Before: 7, After: 7

The table shows the transformation or changes between the "Before" and "After" values across eight different instances. Each pair of numbers represents the before and after values for a specific case, illustrating changes or effects due to an intervention, process, or other influencing factors.
