Question

The number of siblings for a group of sixth grade students is shown below:

0, 1, 2, 1, 6, 0, 2, 0, 1, 10
1,0,2,1,6,0,2,0,1,10.
1,0,2,1,6,0,2,0,1,10.
Find the mean and median of the data.
What does the mean tell you about the data?

Answer 1

To find the mean and median of the given data, we can follow these steps:

Step 1: Arrange the data in ascending order:

0, 0, 0, 1, 1, 1, 2, 2, 6, 10

Step 2: Calculate the mean:

Mean = (Sum of all values) / (Number of values)

Mean = (0 + 0 + 0 + 1 + 1 + 1 + 2 + 2 + 6 + 10) / 10

Mean = 23 / 10

Mean = 2.3

Step 3: Calculate the median:

Since we have an even number of values (10), the median is the average of the two middle values.

Median = (1 + 2) / 2

Median = 3 / 2

Median = 1.5

The mean of the data is 2.3, and the median is 1.5.

The mean tells us the average number of siblings per student in the given data. In this case, the mean is 2.3, which means that on average, the sixth grade students in the group have approximately 2.3 siblings. However, since the number of siblings is a discrete value, it is important to note that the mean may not necessarily represent an actual number of siblings for each student. It is more of a statistical measure that provides an overall representation of the data
