How Do You Spell OUTLIERS?

1. Outliers are data points or observations that significantly differ from the majority of other data points in a sample or a statistical population. They are values that lie at an abnormal distance away from the main cluster of data points. These extreme data values are considered to be "outliers" as they may have resulted from random variation, measurement errors, or may represent true anomalies.

   In statistical analysis, outliers are often seen as problematic or influential observations that can greatly impact the overall analysis or the interpretation of the data. They can skew the results of statistical measures such as the mean (average) and standard deviation, leading to inaccurate conclusions.

   Identifying outliers is crucial for various fields including finance, healthcare, and social sciences. Statistical techniques such as box plots, scatter plots, and Z-score analysis are commonly used to detect outliers. Outliers can be treated in different ways depending on the purpose of the study and the type of analysis conducted. They can be removed from the dataset, transformed, imputed with other values, or analyzed separately to gain insights into the reasons behind their existence.

   Overall, outliers are data instances that greatly deviate from the expected pattern within a dataset and play a vital role in understanding the variability and peculiarities present within the data. Their identification and appropriate treatment are essential for accurate statistical analysis and interpretations.

2. In geol., portions of any stratified group of rocks which lie detached, or out from the main body.
