Find the median of the following data. 24, 14, 13, 26, 12, 18, and 9___________

Answer

To find the median of the given data set: 24, 14, 13, 26, 12, 18, and 9, we will follow these steps:

### Step 1: Arrange the data in ascending order.
We need to sort the numbers from the smallest to the largest.

- Given data: 24, 14, 13, 26, 12, 18, 9
- Arranged in ascending order: 9, 12, 13, 14, 18, 24, 26

### Step 2: Count the number of observations.
Next, we need to determine how many numbers are in our data set.

- The arranged data set has 7 numbers: 9, 12, 13, 14, 18, 24, 26

### Step 3: Determine if the number of observations is odd or even.
Since we have 7 observations, we check if it is odd or even.

- 7 is an odd number.

### Step 4: Find the median.
For an odd number of observations, the median is the middle number in the ordered list.

- The middle number can be found using the formula: (n + 1) / 2, where n is the number of observations.
- Here, n = 7, so (7 + 1) / 2 = 8 / 2 = 4.
- The 4th number in our ordered list is 14.

### Conclusion:
Thus, the median of the data set is **14**.
