What is an outlier in data analytics?
- it is a point in descriptive data that is historical
- it is a point in inferential data that is numeric
- it is a value or data point that varies significantly from others in the data set
- it is a pointer to the sample data set
| Explanation & Hint:
An outlier is defined as a value or data point varying significantly from the others, either much smaller or much greater. Outliers can lead to anomalies in the results obtained, because they can lead to negative effects on the results of your analysis. Outliers have to be cleaned up before the data set can be used for effective analysis. |
