Consider a small dataset, sample= (15, 101, 18, 7, 13, 16, 11,21.5.15, 10,9). It is inferred that 101' is an outlier that is much larger than the other values. 1) Explain any 4 techniques to detect outlier in data (4 Marks] #) Write the R code to detect the outlier using boxplot 3 Marks] in) Write the R code to detect the outlier using IOR [3 Marks]
