Q. Based on the following calculator output, determine the inter-quartile range of the dataset. 1-Var-Stats xˉ=244.857142857Σx=1714Σx2=421554Sx=17.6486880667σx=16.3395101468n=7minX=220Q1=232Med2=240Q3=265maxX=269Answer:
Understand IQR Definition: Understand what the inter-quartile range (IQR) is.The IQR is the difference between the third quartile (Q3) and the first quartile (Q1) of a dataset. It measures the spread of the middle 50% of the data.
Identify Q1 and Q3: Identify the first quartile ( extit{Q1}) and the third quartile ( extit{Q3}) from the calculator output.According to the calculator output, extit{Q1} is 232 and extit{Q3} is 265.
Calculate IQR: Calculate the inter-quartile range (IQR) using the values of Q1 and Q3. IQR=Q3−Q1IQR=265−232IQR=33
