Information About Data Cleaning

There Are Two Types Of Outliers

  • Univariate outliers are extreme values that only relate to one variable. Sultan Kosen, who stands 8 feet, 2.8 inches (251 cm) tall, is the current tallest man in the world. This case is a rare univariate exception because it has one factor, height.
  • Multivariate outliers are combinations of extreme or unusual values for at most two variables. If you look at the height and weight of an adult group, you may notice that one person is 5ft 9ins tall. This measurement would be within the normal range of this variable. This person might also be 110 lbs. This observation is within the normal range of the variable of interest, weight. These two observations are combined to create an adult who stands 5ft 9inches tall and is 110lbs. This is a remarkable combination. This is a multivariate outlier.

Outliers can be classified as any one of the following:

  • Global outliers, also known as point outliers, are data points that lie far from the rest.
  • Contextual outliers, also known as conditional or outliers, are values that significantly differ from the rest of data points in the same context. This means that a value that occurred in a different context may not be considered outlier. This category is often found in time series data.
  • Collective outliers can be described as a subset or group of data points that is completely different from the whole dataset.
    We now know what an outlier looks like, so let’s see how they end up in data sets.

How Can Outliers Get Into Datasets?

After we have learned what outliers look like and how to identify them it is worth asking how they end up in data sets in the first place.
Here are some common reasons for outliers in data:

  • Human error when manually entering data, such a typo
  • Intentional errors such as dummy-outliers in a dataset used to test detection methods
  • Sampling errors are caused by the extraction or mixing of data from incorrect or multiple sources
  • Data processing errors can result from data manipulation or unintended modifications to a dataset.
  • Instrumental error can cause measurement errors
  • Experiment planning and execution errors can result from data extraction or experiment planning.
  • Natural outliers are those that occur naturally in the data, and not because of any error. These errors are called novelties.

How Do You Spot Outliers?

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.

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.

About Hawaii

Hawaii Information

Find Out About Hawaii

HawaiiHawaii is a state located in the Western United States. It is situated in the Pacific Ocean approximately 2,000 miles (3.200 km) from America’s mainland. It is the U.S.’s only state located outside North America and is also the only one that is an archipelago.

History

Hawaii was established by Polynesians between 1000 and 1200 CE. It was also home to many independent chiefdoms. James Cook, a British explorer, was the first non-Polynesian to reach the archipelago in 1778. The flag bears the Union Jack and is an example of British influence. The arrival of European and American explorers and traders as well as whalers soon after led to the destruction of the once-isolated Indigenous community. They introduced diseases like syphilis and measles to reduce the native Hawaiian population to fewer than 40,000.

Climate

Hawaii is blessed with a tropical climate. Because of the east’s near constant trade winds, humidity and temperatures tend to be lower. Summer highs are usually around 88 degrees (31 degrees Celsius) during the day and a low of 75 degrees (24 degC at night). Winter temperatures average 83 degrees Fahrenheit (28 degrees Celsius) during the day, and at low elevations they rarely dip below 65 degrees F (18 degC). In winter, snow, which is not often associated with the tropics can fall at 13,800 feet (4.200 m) on Mauna Kea or Mauna Loa, both on Hawaii Island. Haleakala is not prone to snowfall. Mount Waialeale, on Kauai, has the second-highest annual average rainfall of all places on Earth at 460 inches (12,000mm). The two seasons that Hawaii has are the dry and wet seasons are the same.

Population

The Kingdom of Hawaii period saw the arrival of mainland Americans and Europeans to Hawaii. This markedly increased the population of Hawaii, which was formerly dominated by Indigenous Hawaiians. Many of the Indigenous Hawaiians who died from foreign diseases experienced a decline in their numbers, which fell from 300,000. in 1770s to 60,000 in 1850s to 24,000 by 1920. Other estimates of the pre-contact population range between 150,000 and 1.5 million. In 1923, 42% were of Japanese descent and 9% were of Chinese descent. 16% of the population was of native descent. After the arrival of many migrant workers from Asia at the close of the 19th century, Hawaii’s population began to grow.

Economy

The state’s unemployment rate was 3.2% as of December 2015. The 18% spending made in Hawaii by the United States Military in 2009 was US$12.2 Billion. Hawaii is home to 75,000 personnel from the United States Department of Defense. Phoenix Marketing International found that Hawaii was home to 7.2% of the nation’s millionaires, according to a study from 2013.
