Context: A cognitive research institute administered a high-level analytical reasoning assessment to a group of participants. The individual scores earned on the assessment are recorded below.
Assessment Scores (Unordered Raw Data) Sample Size: n = 12
118 108 132 121 112 136 124 116 122 104 128 119
1 Order the Data in Ascending Order Lowest to Highest
A Mean Calculation Work \(\bar{x} = \frac{\sum x}{n}\)
B Median Position & Value Work Middle value(s)
C Quartiles & IQR Work \(\text{IQR} = Q_3 - Q_1\)
D Standard Deviation Work \(s = \sqrt{\frac{\sum (x-\bar{x})^2}{n-1}}\)
