Dataset I: 1 2 3 4 a) The median of Dataset I is: b) The IQR of Dataset I is from to c) The mean of Dataset I is: d) The standard deviation of Dataset I is: Dataset II: 6 789 10 e) The median of Dataset II is: f) The IQR of Dataset II is from to g) The mean of Dataset II is: h) The standard deviation of Dataset II is: i) Explain the impact (on the meadian, IQR, mean, and standard deviation) of adding 5 to every observation in the dataset. What would happen if we added 13 instead? in
