Book Mean Median Mean absolute deviation Geometry 42.9 4 0 1.2 Science 48.5 42 9 .3
Wat am I supposed to find?
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
It pretty much tells u
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.
yeah which is why I'm thinking the variability is high
re-read what I wrote above
I'm not always perfect, so you may be correct. I'm still sticking with my answer though.
Same. Go wit Kim's answer
Jim. Sry autocorrect
Yes. He is right
k sry lol thanks! :)
