Answer 1

An outller is an extremely high on or extremely low value in our data, we can identity on outller if it is greater than Q3 + 1,5(IQR) (012 Q, -105 (IDR). lower than 17) Given data in ascending order 2. 2 3 4 6 15 divide the data into two, halfs sets find mean of each halt set it it is Qi and

median of first half = 2 = Q, median of second hald, Q = 6 I OR Q - Q, 6-2 - 4 9z+ (1.5) I&R = 6+ B) (H) 3 le 122 ar- 15TOR 2 () (41) The data points above 12 are outliers of below outlier 15 19) mean with outliers 2+2 +3 +476415 6 = 32 5.33 mean without outliers - 2-42+ 3+ 4+G s.
