Given Q1=20,Q2=35,Q3=50Q_1 = 20, Q_2 = 35, Q_3 = 50Q1=20,Q2=35,Q3=50. Is a value of 909090 an outlier using the 1.5×IQR1.5 \times IQR1.5×IQR rule?
Yes, because 90>Q3+1.5×IQR90 > Q_3 + 1.5 \times IQR90>Q3+1.5×IQR.
No, because 90<Q3+1.5×IQR90 < Q_3 + 1.5 \times IQR90<Q3+1.5×IQR.
Yes, because 90>Q3+IQR90 > Q_3 + IQR90>Q3+IQR.
