Carlton is using the following data samples to make a claim about the house values in his neighborhood:

House Value
A $100,000
B $600,000
C $650,000
D $700,000
E $900,000

Based on the data, should Carlton use the mean or the median to make an inference about the house values in his neighborhood?
He should use the median because there is an outlier that affects the mean.
He should use the mean because there are no outliers that affect the mean.
He should use the mean because it is in the center of the data.
He should use the median because it is in the center of the data.

You can tell there is an outlier which is A because 100,000 is a big difference from the other values the mean is inaccurate due to the outlier.   Does this make sense?

Esther wants to know if the number of words on a page in her language arts book is generally more than the number of words on a page in her social studies 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
Language arts	78.5	60	14.2
Social studies	68.7	65	9.8


She claims that because the mean number of words on each page of the language arts book is greater than the mean number of words on each page of the social studies book, the language arts 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 language arts book data
 No, because there is a lot of variability in the language arts book data
 Yes, because the mean is larger in the language arts book
 No, because the mean is larger in the social studies book
