3. To explore whether iodine uptakes on lung computerized tomography (CT)

functional imaging differ between different lung cancer types, 19 patients with different types of lung cancer were enrolled. The patients’ iodine uptake (Hounsfield unit: HU) on CT functional imaging was measured and is given in Table 9.14.

(a) Compare the lodine uptake of the three groups using an appropriate method and Interpret the results.

(b) If necessary, conduct Tukey's, Dunnett's, and LSD-t tests and discuss the differ- ences in the results obtained using these methods. What are their advantages over Independent samples t-tests?
