Final answer:
The question pertains to calculating the mean absolute deviation (MAD) of the ages of Donna's brothers in Mathematics. Without specific ages provided in the question, we cannot calculate the MAD. The process involves calculating the mean age, finding absolute differences, adding them up, and dividing by the number of data points.
Step-by-step explanation:
The subject of the question is Mathematics, specifically referring to statistics and the concept of the mean absolute deviation (MAD). The MAD is a measure of how spread out numbers are in a data set. It is calculated by finding the absolute differences between each data point and the mean, then taking the average of those differences. However, the question does not provide specific ages that can be used to calculate the mean absolute deviation of Donna's brothers.
To illustrate how to calculate the MAD, let's assume we have the ages of Donna's brothers. We would first calculate the mean (average) age of the brothers. Next, find the absolute difference between each brother's age and the mean age. Add up all the absolute differences and divide by the number of data points (brothers) to find the MAD.
For example, if we had a data set with the ages of Donna's brothers, we would follow these steps:
- Calculate the mean of the ages.
- Calculate the absolute difference between each age and the mean.
- Add together all the absolute differences.
- Divide by the number of ages to find the MAD.
Since the question does not give specific ages, we are unable to provide an exact answer to the mean absolute deviation for the ages of Donna's brothers.
