Melissa wants to know if the number of words on a page in her geography 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, then calculates the mean, median, and mean absolute deviation for the 25 samples of each book.
Mean Median Mean Absolute Deviation
Geography 48.9 41 9.2
Math 34.5 44 1.9
She claims that because the mean number of words on each page in the geography book is greater than the mean number of words on each page in the math book, the geography book has more words per page. Based on the data, is this a valid inference?
Yes, because the mean is larger in the geography book
No, because the mean is larger in the geography book
No, because there is a lot of variability in the geography book data
Yes, because there is a lot of variability in the geography book data

yes, I did
so wich one do u think and y
The mean absolute deviation determines the amount of variability. The bigger the mean absolute deviation, the more variability there is.The more variability there is in this case, the less reliable Melissa's conclusion is. It's not valid because there is a lot of variability.
