Information About Data Cleaning And Data Services


Surveys and Questionnaires

Surveys and questionnaires are another way to gather quantitative data. It’s simple to create and distribute a survey online using tools such as SurveyMonkey, Typeform, and Qualtrics. Anyone can now collect quantitative data with ease. Surveys can be used to gather customer feedback or user opinions, or simply find out what people think about certain products and services.

It is important to ask respondents for quantitative data in order to gather meaningful information from surveys. For example, they should be asked to rate their satisfaction on an 0-to-10 scale.

Online Access to Open-Source Data

Data analysts may also be able to analyze data from other databases. It all depends on what field you are working in and the type of data you require. The internet is full of free and open datasets spanning a range of sectors, from government, business and finance, to science, transport, film, and entertainment–pretty much anything you can think of.

What Is the Best Way to Analyze Quantitative Data?

One of the most important characteristics of quantitative data is their ability to be used for statistical analysis. There are many methods and techniques for quantitative data analysis. The way you analyze your data will depend on what you want to learn.

It is important to know the difference between descriptive and inferential analysis before you dive into specific methods of analysis.

What Is the Difference Between Descriptive Analysis and Inferential Analysis?

Descriptive analysis is exactly what it sounds like. It describes the data. This is very useful because it allows you to quickly see the fundamental characteristics of your data and the information you are working with. The most common descriptive statistics are the range (the difference in highest and lowest scores), minimum and maximum (the lowest or highest scores in a data set), and frequency (how frequently a particular value appears in the data set).

To gauge the overall trend of your data, you might calculate different measures of central tendencies. The measures of central tendencies include the mean (the sum all values divided by the number), the median (the middle score when all the scores are ordered numerically) and the mode (the most commonly occurring score). The standard deviation is another useful calculation. This will tell you how representative the whole dataset is.

Although descriptive statistics can give you a quick overview of your quantitative data, they do not allow you to draw any definitive conclusions. Inferential analysis is where you come in. Inferential statistics allows you to make predictions and infer conclusions. This allows you test different hypotheses and predict future outcomes using probability theory.

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.

City of Houston TX Information
Houston TX

Houston is the largest city in Texas and the fourth-most populous in the Southern United States. It also ranks sixth in North America’s population with 2,304,580 residents in 2020. It is located in Southeast Texas, near Galveston Bay, the Gulf of Mexico and is the seat and largest municipality of Harris County. It is also the principal city of Greater Houston Metropolitan Area, which is the fifth most populous metropolitan statistical areas in the United States. Houston is the Southeast anchor of the larger megaregion, known as the Texas Triangle.


Houston is located on land that was once home to the Karankawa as well as the Atakapa people for more than 2,000 years before any settlers arrived. The existence of these tribes is almost impossible today, most likely due to competition with other settler groups in 18th and 19th century. The land was largely uninhabited up until the 1830s when settlement began.


Houston’s climate is humid subtropical (Cfa) according to the Koppen climate classification. This is typical for the Southern United States. Although not located in Tornado Alley like most of Northern Texas, tornadoes can sometimes be seen in the area from spring supercell thunderstorms. Prevailing winds blow from the southeast and south most of the year. They bring heat from Galveston Bay and the Gulf of Mexico.


According to the 2020 U.S. Census, Houston had a population estimate of 2,304,000. The population of Houston was 2,312,717 in 2017, and 2,325,502 in 2018. In 2017, nearly 9% of Houston’s metropolitan population was made up of 600,000 undocumented immigrants. Houston’s population was 2,100,263 at the 2010 United States Census. This is an increase from the 2,396 residents in the 1850 census.


Houston is a car-dependent city. In 2016, 77.2% of Houston commuters drove alone to work, up from 71.7% and 75.6% respectively in 1990 and 2009. Another 11.4% of Houstonians commuted by car to work in 2016, while 3.6% took public transit, 2.1% walked and 0.5% cycled. According to a 2012 commuting study, the average commute time in the region was 12.2 mi (19.6 km). The average commute to work in Houston (city), takes 26.3 minutes, according to the American Community Survey 2013. According to a Murdoch University study, Houston has the longest commute time and lowest urban density among 13 large American cities. A 2017 Arcadis study placed Houston 22nd in terms of transportation sustainability. Harris County ranks second in America in gasoline consumption, behind Los Angeles County.

Top Businesses

Houston is recognized worldwide for its energy industry–particularly for oil and natural gas–as well as for biomedical research and aeronautics. The city is also a growing center for renewable energy sources, such as solar and wind. In fact, the City Government buys 90% of its 1 TWh annual power mostly from solar and some from wind. It has been a hub for tech startup companies. Crown Castle, KBR and Cybersoft are some of the major technology and software firms in Greater Houston. Hewlett Packard Enterprise moved its global headquarters from California in the Greater Houston area on April 4, 2022. Houston’s economic base also includes the Houston Ship Channel.
