The number of cars in 20 families are given below:
1, 1, 2, 3, 4, 3, 2, 1, 1, 4, 4, 5, 2, 4, 2, 1, 3, 2, 3, 1
Arrange the data in the form of discrete frequency distribution.

Answer

To create a discrete frequency distribution table for the number of cars owned by 20 families, we will follow these steps:

### Step 1: Organize the Data
First, we will list the number of cars owned by each family as provided:
1, 1, 2, 3, 4, 3, 2, 1, 1, 4, 4, 5, 2, 4, 2, 1, 3, 2, 3, 1

### Step 2: Identify Unique Values
Next, we identify the unique numbers of cars from the data:
- The unique values are: 1, 2, 3, 4, 5

### Step 3: Count Frequency
Now, we will count how many times each unique value appears in the data:
- For 1: There are 6 families (1, 1, 1, 1, 1, 1)
- For 2: There are 5 families (2, 2, 2, 2, 2)
- For 3: There are 4 families (3, 3, 3, 3)
- For 4: There are 4 families (4, 4, 4, 4)
- For 5: There is 1 family (5)

### Step 4: Create the Frequency Distribution Table
Now we will create a table with three columns: Number of Cars, Tally Marks, and Frequency.

| Number of Cars | Tally Marks | Frequency |
|----------------|--------------------|-----------|
| 1 | ||||| | | 6 |
| 2 | ||||| | 5 |
| 3 | |||| | 4 |
| 4 | |||| | 4 |
| 5 | | | 1 |

### Step 5: Verify Total Frequency
Finally, we will verify that the total frequency adds up to 20:
- Total = 6 + 5 + 4 + 4 + 1 = 20

Thus, the discrete frequency distribution table is complete.
