This was a nice exercise, but how can we use the height, head length to make a quick approximation of the height of a person if all we find is a skull?

Definitions: Mean:_________________________ Median________________________ Mode:_________________________ Range__________________________ Outlier __________________________ Assign one person to find the mode, one find the range, one find the median and the rest find the mean of the information on our table. Have the others in your group find the mean. Definition of ratio: A comparison of two numbers by division. 2 Mean of height:_______ Mean of head length: _________ Lets do it a better way!!!!!!!!! Ratio of Height/head___________________ Median height: _________Median head length:_________
