Information About Data Cleaning And Data Services

Data Cleaning in Charlotte North Carolina from NW Database Services

What Is an Outlier?

There is much to do before you can begin the analysis phase of data analytics. The data analytics process can take up to two-thirds of its time to clean “dirty” data. This is data that must be edited, worked upon, or modified in any other way before it can be used for analysis.

Data analysts may discover outliers in “dirty” data during the cleaning phase. This leads to either removing them completely or handling them differently. So, the question is: What is an outlier?

What Is an Exception?

Outliers in data analytics are values that differ significantly from other datasets. They can be either significantly larger or smaller. Outliers can indicate variabilities in measurements, experimental errors or a novelty. A real-world example shows that a giraffe’s average height is 16 feet. Recent discoveries have revealed that two giraffes are 9 and 8.5 feet tall. These two giraffes are considered to be outliers compared to the rest of the giraffe population.

Outliers can lead to anomalies in data analysis results. These outliers can cause problems in data analysis and may need to be addressed.

How Do You Spot Outliers?

Once you have a basic understanding of how outliers are classified, we can move on to how to identify them within your data sets.

It is possible to spot outliers in small datasets. For example, if you have 28 26, 21, 24, and 78 data sets, you can see that the outlier is 78. However, when dealing with large datasets or big-data, additional tools are needed.

Visualizations Can Be Used to Spot Outliers

Data analytics analysts create data visualizations in order to visually present data in a meaningful and compelling way to communicate their findings to the relevant stakeholders. These visualizations are able to show patterns and outliers in large amounts of data using charts, graphs, and maps.

This article will cover the various types of data visualizations. However, here are two options that data analysts could use to quickly find outliers.

Northwest Database Services has 34+ years experience with all types of data services, including mail presorts, NCOA, and data deduplication. If your database systems are not returning poor data, it is definitely time for you to consult with a data services specialist. We have experience with large and small data sets. Often, data requires extensive manipulation to remove corrupt data and restore the database to proper functionality. Call us at (360)841-8168 for a consultation and get the process of data cleaning started as soon as possible.
