Questionnaires and Surveys

Another way to collect quantitative data is through surveys and questionnaires. SurveyMonkey, Typeform and Qualtrics make it easy to create and distribute surveys online. With ease anyone can collect quantitative data. You can use surveys to collect customer feedback, user opinions, or just find out what people think of certain products or services.

In order to get meaningful information from surveys, it is crucial to ask respondents for quantitative information. They should, for example, be asked to rate how satisfied they are with the survey.

Online Access to Open Source Data

Data analysts might also be able analyze data from other databases. It depends on the field and type of data that you need. 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?

The ability to use quantitative data for statistical analysis is one of the most important features of these data. There are many techniques and methods for quantitative data analysis. Your goals will determine the way you analyze your data.

Before you start to explore specific methods of analysis, it is important that you understand the differences between descriptive and inferential analyses.

What Is the Difference Between Descriptive Analysis & Inferential Analysis?

It is exactly what its name suggests. It describes the data. This is very helpful because it allows you quickly to see the basic characteristics of your data as well as the information you work with. Most common descriptive statistics include the range (the difference between the highest and lowest scores), the minimum and maximum scores (the lowest and highest scores in a set of data) and frequency (how often a particular value appears within the data set).

You might use different measures to assess the trend in your data. You can use the following measures to measure central tendencies: the mean (the sum of all values divided by number), the median, the middle score when all scores are ordered numerically, and the mode (the most frequently occurring score). Another useful calculation is the standard deviation. This tells you how representative your entire dataset is.

While descriptive statistics are useful for providing a quick overview of quantitative data, they don’t allow you to draw any conclusions. This is where inferential analysis comes in. Inferential statistics allows for predictions and inferred conclusions. This allows you to test hypotheses and forecast future outcomes with 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.
