Outcomes

NC.7.SP.3a

Calculate the measure of variability of a data set and understand that it describes how the values of the data set vary with a single number. o Understand the mean absolute deviation of a data set is a measure of variability that describes the average distance that points within a data set are from the mean of the data set. o Understand that the range describes the spread of the entire data set. o Understand that the interquartile range describes the spread of the middle 50% of the data.
