Find the mode in each of the following data collection.
5,7,9, 11, 14, 16, 20, 22, 25

Answer

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

### Step 1: Understand the definition of mode
The mode is defined as the number that appears most frequently in a data set. If no number repeats, then there is no mode.

### Step 2: List the data
The data provided is:
5, 7, 9, 11, 14, 16, 20, 22, 25

### Step 3: Count the frequency of each number
Now, we will check how many times each number appears in the data set:
- 5 appears **1 time**
- 7 appears **1 time**
- 9 appears **1 time**
- 11 appears **1 time**
- 14 appears **1 time**
- 16 appears **1 time**
- 20 appears **1 time**
- 22 appears **1 time**
- 25 appears **1 time**

### Step 4: Identify the highest frequency
From the frequency count, we can see that all numbers appear only **once**.

### Step 5: Determine the mode
Since no number appears more than once, there is **no mode** in this data set.

### Final Answer:
The mode of the given data collection is **none** (or "no mode").
