Magdeline wants to know if the number of words on a page in her computer science book is generally more than the number of words on a page in her math book. She takes a random sample of 25 pages in each book and then calculates the mean, median, and mean absolute deviation for the 25 samples of each book. Book Mean Median Mean Absolute Deviation Computer science 48.7 40 9.4 Math 34.2 45 1.9 She claims that because the mean number of words on each page in the computer science book is greater than the mean number of words on each page in the math book, the computer science book has more words per page. Based on the data, is this a valid inference? Yes, because there is a lot of variability in the computer science book data Yes, because the mean is larger in the computer science book No, because the mean is larger in the computer science book No, because there is a lot of variability in the computer science book data

As regards the validity of the inference made by Magdeline on the pages of her textbooks, the answer is No, because there is a lot of variability in the computer science book data.

Why is the inference not valid?

The absolute deviation of a data set shows how much some variables can deviate from the mean.

The high absolute deviation of the computer science book of 9.4 pages means that we can't say for a fact that the computer science book has more words per page than the math book.

This is because there will be some pages in the computer science book that might be 9.4 pages less than the mean.
