Find the mode in each of the following data collection.
, 14, 14, 14, 16, 17, 18, 18, 18, 20, 22, 22, 22, 25, 28, 28, 30

Answer

To find the mode of the given data collection, we will follow these steps:

### Step 1: List the Data
The data provided is:
14, 14, 14, 16, 17, 18, 18, 18, 20, 22, 22, 22, 25, 28, 28, 30

### Step 2: Count the Frequency of Each Number
Now, we will count how many times each number appears in the data set:

- 14 appears **3 times**
- 16 appears **1 time**
- 17 appears **1 time**
- 18 appears **3 times**
- 20 appears **1 time**
- 22 appears **3 times**
- 25 appears **1 time**
- 28 appears **2 times**
- 30 appears **1 time**

### Step 3: Identify the Highest Frequency
Next, we need to identify which number(s) appear the most frequently. From our counts, we see:

- 14: 3 times
- 18: 3 times
- 22: 3 times

### Step 4: Determine the Mode
Since 14, 18, and 22 all appear 3 times, they are the mode of this data set.

Thus, the mode is:
**14, 18, and 22**

### Summary of the Solution
The mode of the given data collection is **14, 18, and 22**.
