Answer:
- The mean of the given data set without outlier is 1.4
Explanation:
We can observe the outlier without any calculations, it is 7.
The outlier is the data point that is extremely high or low compared to the rest of data.
The mean of the data set excluding the outlier is:
- mean = sum of terms / number of terms
- mean = (1 + 0 + 1 + 3 + 2)/5 = 7/5 = 1.4
