In statistics, outliers are values outside the norm relative to the rest of collected data. Many times they can skew the results and distort the interpretation of data. They may or may not indicate anything significant; they might just be an anomalous data point that is not significant. It is difficult to tell.

there are no limits to outliers there are no limits to outliers
What is unaffected by outliers?
interquartile range
Does outliers affects data?
No. Outliers are part of the data and do not affect them. They will, however, affect statistics based on the data and inferences based on the data.
How do outliers influence the shape and spread of the data?
Outliers will make give the graph a long tail (or tails). Overall, the graph will be flatter and wider.
Is the variance impacted by extreme outliers?
Yes, it is.

Why are outliers bad?
Outliers can be problematic because they can skew statistical analyses, leading to misleading interpretations and poor decision-making. They may indicate data entry errors, measurement issues, or represent rare events that don't reflect the overall trend. In predictive modeling, outliers can disproportionately influence results, undermining the model's accuracy and reliability. Therefore, identifying and addressing outliers is crucial for maintaining the integrity of data analysis.
What do outliers on a scatter plot indicate?
Simply that there were some observations that were very much smaller or very much larger than most of the rest.

How many pages does Outliers - book - have?

What are data points that do not fit with the rest of a data set?
Data points that do not fit with the rest of a data set are known as outliers. These values are significantly different from the majority of the data, either much higher or lower, and can skew statistical analyses. Outliers may arise from variability in the data, measurement errors, or they could indicate a novel phenomenon worth investigating. Identifying and understanding outliers is crucial for accurate data interpretation.
Can there be 2 outliers in a set of data?
There is no limit to the number of outliers there can be in a set of data.

What does the whisker in a box-and-whisker plot represent?
The whiskers mark the ends of the range of figures - they are the furthest outliers. * * * * * No. Outliers are not part of a box and whiskers plot. The whiskers mark the ends of the minimum and maximum observations EXCLUDING outliers. Outliers, if any, are marked with an X.
Can you safely remove outliers from scatter charts?
You can only do it if either the outliers are way out - so far that they must be odd, so far that there can be no argument, no need for statistics to prove them to be outliers, or you need to prove that they are outliers using statistics - something like Grubb's test. To do that, the simplest way is software.
