Information About Data Cleaning

Interval Vs. Ratio Data

You can also measure interval data along a continuum. This means that each point on the continuum is equally distant. Ex.: A difference of 30 degrees C and 31 degree C equals 99 degrees or 100 degrees. Interval data doesn’t have a meaningful zero value. Here’s an example: Temperature. Temperatures below zero do not necessarily indicate that there is no temperature. It simply means that it is extremely cold.

Ratio data is very similar to interval data in terms of the number of points on the scale. But, unlike interval data ratio data has a zero. Ratio data refers to weight in grams. The difference between 20 grams and 21 grams is equal to the difference between 8 and 9 grams. It really doesn’t matter how much something weighs if it weighs zero grams.

Quantitative data can further be broken down into other types beyond the distinction between continuous or discrete data.

Measurements: These measurements are used to measure physical items. You might need to measure the length and width of your living area before ordering a new sofa.

Sensors: A sensor is a device that detects environmental changes and sends it to an electronic device (usually a computer). This information is then converted into numbers, which is your quantitative data. For example, a smart temperature sensor will provide you with data throughout the day about the temperature.

Counts: These are quantitative data you get when you count things. You could count how many people visited your site within a week, or the number of people who attended an event.

Quantification of Qualitative Data: When qualitative data is converted into numbers. Let’s use customer satisfaction as an example. Qualitative data could include customer satisfaction statements such as “I’m really happy with this product.” This data could be converted to quantitative data by asking customers for their satisfaction ratings on a scale of 1-10.

Calculations: This is any quantitative data that can be derived from mathematical calculations. You might, for example, calculate your monthly final profits.

Projections: Analysts use algorithms, artificial intelligence, or “manual analyses” to project or estimate quantities. For example, you might predict how many sales you will make in the next quarter. This is an example of quantitative information.

Knowing what type of quantitative data you have is crucial in order to be able to apply the correct statistical analysis. Section five will discuss how quantitative data can be analyzed.

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.

About Massachusetts

Massachusetts Information

Find Out About Massachusetts

MassachusettsOfficially, Massachusetts is the Commonwealth of Massachusetts. It is the most populous state of the Northeastern United States. It borders the Atlantic Ocean and Gulf of Maine east, Connecticut and Rhode Island south, New Hampshire, Vermont north, and New York west. Massachusetts is the sixth-smallest state in terms of land area, but it is also the 15th most populous and 3rd most densely packed after New Jersey (and Rhode Island). Boston is the capital of Massachusetts and its most populous city. It also serves as the state’s cultural and financial centre. The urban core of Greater Boston is the largest metropolitan area in New England. It has a profound impact on American history, academia and the research economy. Massachusetts was originally dependent on agriculture, fishing, trade, and other natural resources. The Industrial Revolution transformed Massachusetts into a major manufacturing hub. Massachusetts’s economy changed from manufacturing to services during the 20th century. Modern Massachusetts is a leader in biotechnology and engineering, higher education, finance and maritime trade.


Massachusetts was an early English colony. The Pilgrims on the Mayflower founded the Plymouth Colony in 1620. In 1630, the Massachusetts Bay Colony established settlements at Salem and Boston. The Salem witch trials, one of America’s most notorious cases of mass hysteria in America, occurred in 1692. General Henry Knox, a general, founded the Springfield Armory in 1777. This was a catalyst for many technological advancements, including interchangeable parts, during the Industrial Revolution. The United States Constitutional Convention was influenced by Shays’ Rebellion in 1786. It was a popular revolt led by disaffected veterans of the American Revolutionary War. The pulpit of Northampton preacher Jonathan Edwards was the source of the Protestant First Great Awakening in the 18th century. It swept Britain, and the Thirteen Colonies. Boston was known as the “Cradle of Liberty” in the late 18th-century for the agitation that led to the American Revolution.

Major Cities & Towns

Massachusetts is small but has many topographically unique areas. Greater Boston is located in the state’s eastern coastal region. This includes most of its population and the Cape Cod peninsula. The Connecticut River Valley is located to the west, as well as the hilly, rural area of Central Massachusetts. The Berkshires, which form a part of the Appalachian Mountains’ northern terminus, are located along the state’s western border.


Massachusetts is characterized by a humid continental climate with warm summers and cold winters. The broad transition zone from Humid Subtropical climates is found along the coasts of the far southeast. This transition is limited to areas along the coast, such as the Barnstable County peninsula. The oceanic climate is rare due to the warm to hot summers. The climate in Boston is very representative of the commonwealth. It is characterized by high summer temperatures of around 81 degrees (27 degreesC) and low winter temperatures of 35 degrees (2 degC). It is also quite wet. Frosts can be seen all winter long, even in coastal regions due to the prevailing inland wind. Massachusetts’s location close to the Atlantic makes it vulnerable to hurricanes, nor’easters and tropical storms.


The 2020 U.S. Census showed that Massachusetts had more than 7 million people, an increase of 7.4% since 2010. With 871.0 people per sq mile, Massachusetts was third in the United States for densely populated states. This is behind Rhode Island and New Jersey. The state had 1,011,811 residents who were foreign-born in 2014, which is 15% of its population. The population was estimated to have dropped to 6.98million as of July 2021.


According to the United States Bureau of Economic Analysis, Massachusetts’ gross state product for 2020 is $584 billion. It was the third-highest US state with a per capita income of $53,221. The Massachusetts state’s minimum wage was $15.00 an hour as of January 2023. Tip workers earn $6.75 an hour. Employers are guaranteed to pay the difference if the hourly wage earned by a tipped worker is less than or equal to the general minimum wage. In January 2023, the wage will increase to $15.00 an hour for a general worker and $6.75 for a tipped employee. This was part of a series amendments to the minimum wage laws in 2018. The minimum wage increased slowly from January 2018 to 2023.
