What is an outlier?
An outlier can be defined as a data point that differs significantly or greatly from other observations.
It occurs as a result of;
- variability in the measurement
- indication of novel data
- experimental error
From the information given, we have that;
121, 89, 410, 203, 55, 230, 182, 148, 135, 233, 11, 219, 108, 192
Since, the outlier is 410
The mean is given as;
= 121 + 89+ 203+ 55 + 230+182 + 148 + 135 + 233+ 11+ 219 + 108 + 192/13
Add the values
= 1696/13
= 130. 5
Hence, the value is 130. 5
