what happens if there is a mode in your set of data but you have to do a box plot?
The mode of a data set has absolutely no relevance to a box plot. A box plot looks like this:
|(minimum value)---------|(lower quartile/Q1)=====|(median)=======|(upper quartile/Q3)----------------------|(maximum value)
Fast facts about a box plot:
IQR (inter-quartile range) = Q3 - Q1
Range = Maximum - Minimum
Lower half of the data is in between the minimum and the median
The upper half of the data is between the median and the maximum
The middle half of the data is in between Q1 and Q3.
