What is an outlier? This lesson presents the concept of outliers in statistics, displays examples, and shows how to find them. Related to this Question What is the difference between trends and outliers for a set of data? What is standard deviation?
The steps to find an outlier: 1. Put the data in numerical order. 2. Find the median. 3. Find the medians for the top and bottom parts of the data. This divides the data into 4 equal parts. The median with the smallest value is called Q1. The median for all the values - usuall...

What is an Outlier? An outlier is any data point which differs greatly from the rest of the observations in a dataset. Let’s see some real life examples to understand outlier detection: When one student averages over 90% while the rest of the class is at 70% – a clear outlier While...
1. What is an outlier? In data analytics, outliers are values within a dataset that vary greatly from the others—they’re either much larger, or significantly smaller. Outliers may indicate variabilities in a measurement, experimental errors, or a novelty. ...
Data cleansing, also referred to as data cleaning or data scrubbing, is the process of fixing incorrect, incomplete, duplicate or otherwise erroneous data in a data set. It involves identifying data errors and then changing, updating or removing data to correct them. Data cleansing improvesdata ...
Data science is useful in every industry, but it may be the most important in cybersecurity. For example, international cybersecurity firm Kaspersky uses science and machine learning to detect hundreds of thousands of new samples of malware on a daily basis. Being able to instantaneously detect ...
