To find the average number of siblings that your classmates have, we will calculate both the mean and median. You provided the data set:
\[ 0, 1, 3, 4, 2, 4, 3, 2, 4, 1, 4, 6, 2, 4, 7, 1, 4, 10 \]
Step 1: Mean Calculation
To calculate the mean, we need to sum all the values and then divide by the number of values:
- Sum the values:
\[ 0 + 1 + 3 + 4 + 2 + 4 + 3 + 2 + 4 + 1 + 4 + 6 + 2 + 4 + 7 + 1 + 4 + 10 = 56 \]
- Count the number of values:
There are 18 values in total.
- Calculate the mean:
\[ \text{Mean} = \frac{\text{Sum}}{\text{Number of values}} = \frac{56}{18} \approx 3.11 \]
Step 2: Median Calculation
To calculate the median, we need to first arrange the values in ascending order:
\[ 0, 1, 1, 1, 2, 2, 2, 3, 3, 4, 4, 4, 4, 4, 6, 7, 10 \]
Now we can find the median. Since there are 18 values (an even number), the median will be the average of the 9th and 10th values in the ordered list.
- Find the 9th and 10th values:
The 9th value is 3 and the 10th value is 4.
- Calculate the median:
\[ \text{Median} = \frac{3 + 4}{2} = \frac{7}{2} = 3.5 \]
Summary
- Mean: approximately 3.11
- Median: 3.5
Thus, the average number of siblings that your classmates have is approximately \(3.11\) (mean), and the median number of siblings is \(3.5\).
