Learning Target 1.5A: I can compute measures of center (mean, median) and variability (IQR, MAD, SD).  

Learning Target 1.5B: I can say something about a data set using measures of center and variability. 

Learning Target 1.5C: I can compute statistics using technology tools.

(particularly Desmos or TI-84 Calculator)
