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 Chattanooga TN Information

Chattanooga Tennessee

Chattanooga, Tennessee is the county seat and city of Hamilton County. It is located along the Tennessee River, which borders Georgia. On its western end, it extends into Marion County.


Native Americans were the first to settle in Chattanooga. Sites dating back to the Upper Paleolithic period (c. 10,000 BCE) show continuous human occupation through the Archaic, Woodland, Mississippian/Muskogean/Yuchi (900-1714 CE), and Cherokee (1776-1838) periods. The Chickamauga Mound is located near the Chickamauga Creek mouth and is the oldest visible art (c.750 CE).


Chattanooga has a humid subtropical four-season climate, as does much of Tennessee. Winter days are typically mild. However, most years have at minimum one day (average 3.2), where the temperature is below freezing. The amount of snowfall varies greatly from one year to the next. Between January 9-10 2011, snowfall was recorded at 11 inches (28cm). Between January 9-10, 2011, temperatures reached 11 inches (28 cm) in the summer. There are 52 days a year when temperatures reach 90 degrees Fahrenheit (32 degC), or higher. Climate change has made Chattanooga the sixth-warmest city in America.


The city was home to 167,674 people and 70,749 families, as well as 40,384 families, according to the 2010 census. Population density was 1,222.5 people per square mile (472.0/km2). The average density of housing units was 588.8/square mile (2227.3/km2). There were 79,607. The city’s racial composition was 58.0% white, 34.9% black, 2.0% Asian and 0.4% American Indian. There were also 2.1% Pacific Islander, 2.8% other races, 1.9% from more than one race, and 2.8% from another race. 5.5% of the population was Hispanic/Latino. Non-Hispanic whites accounted for 55.9% of 2010’s population, a decrease from 67.3% in 80.


Chattanooga is considered to be the gateway into the Deep South. It also serves as the Midwest and Northeast for motorists coming from other states like Alabama, Florida and Georgia. Chattanooga has a complex transportation infrastructure that includes interstates and tunnels, roads, bridges and railroad lines. Chattanooga, a small city of mid-sized, is considered to have the most severe traffic congestion among cities of its size. This is due to an unusually high volume of truck traffic. Cambridge Systematics’ 2015 study found that almost 80% of the trucks that pass Chattanooga go to another location. This is the highest percentage of any major metropolitan area in the United States.
