Range, IQR and Standard Deviation

1. IQR stands for interquartile range. “Interquartile” looks like a strange and difficult word, but we can break it down into easier parts.

   • Range is the difference between the largest and smallest number in the data set.
   • Generally speaking, standard deviation compares how spread out your numbers are to the mean of your data set.
