Hoaglin, Mosteller, and Tukey (1983) present data on blood levels of beta-endorphin as a function of stress. They took beta-endorphin levels for 19 patients 12 hours before surgery, and again 10 minutes before surgery. The data are presented below, in fmol/ml: 1 2 3 4 5 6 7 8 9 10 ID 12 hours 10.0 6.5 8.0 12.0 5.0 11.5 5.0 3.5 7.5 5.8 10 minutes 6.5 14.0 13.5 18.0 14.5 9.0 18.0 42.0 7.5 6.0 ID 11 12 13 14 15 16 17 18 19 12 hours 4.7 8.0 7.0 17.0 8.8 17.0 15.0 4.4 2.0 10 minutes 25.0 12.0 52.0 20.0 16.0 15.0 11.5 2.5 2.0 O Cengage Learning 2013

Question

Calculate the effect size of the data below?

The table, based on research by Hoaglin, Mosteller, and Tukey (1983), shows beta-endorphin levels in the blood of 19 patients at two different times: 12 hours before surgery and 10 minutes before surgery. The measurement unit is femtomoles per milliliter (fmol/ml).

**Table Explanation:**
- **Column Labels (ID):** Each column represents a patient, labeled numerically from 1 to 19.
- **Rows:**
  - **12 hours:** Displays beta-endorphin levels for each patient taken 12 hours prior to surgery.
  - **10 minutes:** Displays levels for each patient 10 minutes before surgery.

**Data:**

- **Patients 1 to 10:**
  - Beta-endorphin levels 12 hours before surgery range from 3.5 to 12.0 fmol/ml.
  - Levels 10 minutes before surgery range from 5.8 to 42.0 fmol/ml.

- **Patients 11 to 19:**
  - Levels 12 hours before surgery vary from 4.4 to 17.0 fmol/ml.
  - Levels 10 minutes before surgery vary from 2.0 to 52.0 fmol/ml.

This data suggests fluctuations in beta-endorphin levels in response to the stress of impending surgery.
