0.15 1.54 2.62 4.12 0.34 1.82 2.77 4.32 0.48 2.05 3.15 4.51 0.92 2.26 3.55 4.73 1.07 2.36 3.81 5.02 Solution
excel is used to do the analysis.
upper fence is =Q3+1,5*IQR= 3.8875+1.5*2.465=7.5850
lower fence is =Q1-1.5*IQR=1.4225-1.5*2.465=-2.275
No, all the values are between the upper and lower fences.
There are no outliers.
