Question 1176521
Absolutely! Let's compute the quartiles, interquartile range (IQR), and range for each dataset.

**A. Math Scores in Science:**

1.  **Arrange the data in ascending order:**
    16, 18, 20, 20, 22, 23, 25, 26, 27, 34, 36, 37, 39, 41

2.  **Find the quartiles:**
    * **Q1 (First Quartile):** The median of the lower half of the data. Since there are 14 data points, the lower half contains the first 7 values. The median of these values is the average of 20 and 22, which is 21.
    * **Q2 (Second Quartile/Median):** The median of the entire dataset. The median is the average of 25 and 26, which is 25.5.
    * **Q3 (Third Quartile):** The median of the upper half of the data. The upper half contains the last 7 values. The median of these values is the average of 36 and 37, which is 36.5.

3.  **Calculate the Interquartile Range (IQR):**
    * IQR = Q3 - Q1 = 36.5 - 21 = 15.5

4.  **Calculate the Range:**
    * Range = Maximum value - Minimum value = 41 - 16 = 25

**Results for Math Scores:**

* Q1: 21
* Q2 (Median): 25.5
* Q3: 36.5
* IQR: 15.5
* Range: 25

**B. Number of Hours Spent Using Social Media:**

1.  **Arrange the data in ascending order:**
    105, 107, 109, 111, 112, 115, 123, 126, 128, 128, 130

2.  **Find the quartiles:**
    * **Q1 (First Quartile):** The median of the lower half of the data. Since there are 11 data points, the lower half contains the first 5 values. The median of these values is 109.
    * **Q2 (Second Quartile/Median):** The median of the entire dataset, which is 115.
    * **Q3 (Third Quartile):** The median of the upper half of the data. The upper half contains the last 5 values. The median of these values is 128.

3.  **Calculate the Interquartile Range (IQR):**
    * IQR = Q3 - Q1 = 128 - 109 = 19

4.  **Calculate the Range:**
    * Range = Maximum value - Minimum value = 130 - 105 = 25

**Results for Social Media Hours:**

* Q1: 109
* Q2 (Median): 115
* Q3: 128
* IQR: 19
* Range: 25
