Information About Data Cleaning And Data Services

Data Cleaning in Charlotte North Carolina from NW Database Services

Box Plots Can Be Used to Identify Outliers

It is easy to identify outliers by visualizing data in a box plot. The box plot will display the “box”, which represents the interquartile range (from lower quartiles to the upper), and any outliers outside of the “whiskers”. Each side represents the minimum and maximum data values. The prominent outlier will be the minimum value if the box is closer to the maximum whisker. The prominent outlier for boxes that are closer to the minimum-valued whisker would be the maximum value. You can easily create box plots in Excel or Python using a module like Plotly.

Scatter Plots Can Be Used to Identify Outliers

Scatter plots, as the name implies, show scatterplots which display the values of a dataset “scattered on an axis” for two variables. Outliers will be easily visible in scatter plot visualizations. These will be data points that are farthest from the regression line (a single line that is the most fitting the data). These visualizations can be created in Excel or Python, just like box plots.

How to Spot Outliers with Statistical Methods

Data analysts may employ statistical methods to aid in machine learning modeling. This can include identifying, understanding and, in some cases, eliminating outliers.

We’ll be discussing two common algorithms for identifying outliers. However, there are many other options that could prove more useful in your analysis.

Dbscan Can Help You Identify Outliers

DBSCAN (Density Based Spatial clustering of Applications with Noise), is a method for clustering that’s used in machine-learning and data analytics. DBSCAN graphically represents the relationships between features, trends, and populations within a dataset. It can also be used to detect outliers.

DBSCAN is a density-based clustering algorithm that uses non-parametric algorithms. It focuses on finding neighbors who are close together. Outliers are points that exist in isolated low-density areas, far from their neighbors.

DBSCAN is a data analyst and machine learning specialist that will be familiar to data analysts. It’s an algorithm that has been around since 1996. And, with it winning a ‘test-of-time award’ at a major data mining conference, it looks like it’s going on to stay a industry standard. DBSCAN implementations can be found in scikit, R and Python.

Find the Z-Score to Identify Outliers

Z-score, also known as the standard score, is defined by Wikipedia as the “number of standard deviations” that determine whether the value of a raw (or observed value) is higher or lower than the mean value of what is being measured or observed.

A z-score is a way to describe any data point. It places it in relation with the standard deviation or mean of all data points. Negative standard scores are below the mean. Positive standard scores are raw scores that are above the mean. Normal distributions are created by the standard deviation being 1 and the mean being 0.

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.

City of Greensboro NC Information

Greensboro Carolina

Greensboro was once a city and the county seat in Guilford County, North Carolina. It is third in North Carolina, after Raleigh and Charlotte, and the 69th most populous US city. It is also the largest city within the Piedmont Triad metropolitan area. It had 299,035 people at the 2020 census. It is the intersection point of three major interstate highways, Interstate 40, Interstate 85 and Interstate 73 in central North Carolina’s Piedmont region.

History

Greensborough, the spelling before 1895, was built around a central square courthouse square in 1808. It succeeded Guilford Court House to become the county seat. Thus, the county courts were placed closer to the county’s geographic center. This was a more accessible location for most of the county’s citizens who traveled on horseback or by foot at that time.

Climate

Greensboro, like most of the southeastern United States has a humid subtropical environment with four distinct seasons. The winters are generally short and cool with an average January temperature of 38.9 degrees F (3.8 degrees Celsius). There are an average of 75 nights that fall below freezing and 4.3 days when temperatures rise above freezing. Nearly every winter, snowfall is measured and averages 7.5 inches (19.1cm), but it varies greatly from one winter to the next. The facilitation of freezing rain by cold-air damming can be a greater concern than snow.

Demographics

According to the 2020 United States Census, the city had 299,035 residents, 118,046 families, and 69.420 families. The 2019 U.S. Census estimates showed that 296,710 people lived in the city, an increase of the 291,303 according to the 2019 American Community Survey. The 2010 U.S. Census showed that there were 269 666 people, 111 731 households, and 63,244 family members residing in the area. The population density was 2,131.7 per square mile (822.2/km2). At an average density of 980.8 units per square mile (389.6/km2), there were 124,074 housing units.

Transportation

Greensboro is served at Piedmont Triad International Airport. This airport also serves nearby cities High Point and Winston-Salem, as well as the Piedmont Triad Metropolitan region. Piedmont Triad International, North Carolina’s third busiest airport, averages 280 takeoffs/landings per day. PTI was the hub of Skybus Airlines, which is now closed.

Top Businesses

Greensboro’s economy, as well as the Piedmont Triad’s, has been based on textiles, tobacco and furniture. Greensboro’s central position in the state makes it a popular spot for families and businesses. FedEx also has regional operations in the city. It was announced in December 2021 that Toyota Motor North America, which is a subsidiary Japanese automaker Toyota would have a $1.3 million battery plant in Greensboro.
