Unit 5 - Algebra Test Review

Using the data given, determine which answer is correct about DAMIEN'S central tendency.

• Damien's mean is $6 and the median is $4.

• Damien's mean is $4 and the median is $6.

• Damien's mean and the median is $5.

Using the data given, determine which answer is correct about TONY'S central tendency.

• Tony's mean is $6 and the median is $4.

• Tony's mean is $4 and the median is $6.

• Tony's mean and the median is $5.

Damien's mean is $6 and the median is $4. This happens because the value of 28 is an​ (a)   and caused the ​ (b)   to be higher than the ​ (c)   . This would cause the distribution to be ​ (d)   .
