1. A study on the optic nerve anatomy in myopia and glaucoma reported the following mea- surements 0n the area of lamina cribrosa (mm2) from human optic nerve heads: 2.74 2.63 2.74 3.85 2.34 2.74 3.93 4.21 3.89 4.33 3.45 4.52 2.43 3.66 2.78 3.56 3.03 3.00 (a Compute the median and IQR of the data by hand. (b Calculate Ea ac.- and 23.55%. (c (d By accident, the value 3.93 is recorded as 39.3. How much does this affect the average? How much does this affect the median? Use (b) to compute mean and standard deviation. ) ) ) )
