Which number is the lowest ?

Answer

To organize the given marks in a tabular form and find the lowest number, follow these steps:

### Step 1: List the Marks
First, we need to write down all the marks given in the question:
- Marks: 4, 6, 7, 5, 3, 5, 4, 5, 2, 6, 2, 5, 1, 9, 6, 5, 8, 4, 6, 7

### Step 2: Identify the Range of Marks
Next, we identify the range of marks from the lowest to the highest:
- The lowest mark is 1 and the highest mark is 9.

### Step 3: Create a Frequency Table
Now, we will create a frequency table that lists each unique mark and how many times it appears in the data set.

| Marks | Frequency |
|-------|-----------|
| 1 | 1 |
| 2 | 2 |
| 3 | 1 |
| 4 | 3 |
| 5 | 5 |
| 6 | 4 |
| 7 | 2 |
| 8 | 1 |
| 9 | 1 |

### Step 4: Fill in the Frequency
Count how many times each mark appears:
- 1 appears 1 time
- 2 appears 2 times
- 3 appears 1 time
- 4 appears 3 times
- 5 appears 5 times
- 6 appears 4 times
- 7 appears 2 times
- 8 appears 1 time
- 9 appears 1 time

### Step 5: Identify the Lowest Number
From the frequency table, we can see that the lowest number is:
- **1**

### Final Answer
The lowest number in the marks is **1**.
