Kelly wants to know if the number of words on a page in her geometry book is generally more than the number of words on a page in her science 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.

Kelly claims that because the mean number of words on each page in the science book is greater than the mean number of words on each page in the geometry book, the science book has more words per page. Based on the data, is this a valid inference? No, because the mean is larger in the science book No, because there is a lot of variability in the science book data Yes, because the mean is larger in the science book Yes, because there is a lot of variability in the science book data

how did u get that though?

In the table under the word mean, for science it is 48.5 and for math it is 42.9

I don't agree. The variability in the science book is much higher. So the data is much more spread out (meaning that the true center is likely to be different from the mean). There may be an outlier skewing the mean.

I guess but in general, the average is what your looking for. But I definitely do agree

The MAD is quite high.

  • jim_thompson5910
yeah which is why I'm thinking the variability is high
