Finding, Understanding and Conducting Research Studies


Quantitative Studies

"Quantitative research consists of the collection, tabulation, summarization, and analysis of numerical data for the purpose of answering research questions or hypotheses" (Levine, 2017).

In addition,

"Quantitative research is concerned with making generalizations from a study sample to a target population, a process called statistical inference" (Levine, 2017).

To put it in lay terms, quantitative research is all about things that can be measured.

Finding Quantitative Articles

Unlike some of the studies you will be looking for, there is not a specific limiter to add to your searches to limit to just quantitative articles. One way you can narrow down to these studies is to add a search term of quantitative to your search string. See example below:

heart disease AND diet AND quantitative

Then you will need to read through the article abstracts of the results to determine if the study meets the criteria of a quantitative study.  

In addition, there are a few things you can do in various types of searching to help you narrow down to these types of studies. 

Using the Search Everything Tab

1. Search for your topic using the Search Everything tab on the library homepage.

2. Select the Peer-Reviewed limiter, and enter the Publication Date range 2015-2020.

3. You can also look for statistics as a subject under the Subject limiter. Click on the Show More link to see the full list of subjects. This can help you narrow to articles reporting statistics, which will give you a better chance of finding a quantitative study.

Search Articles and Other Databases

With the article search and other databases, look for a limiter that either says scholarly journals or peer-review to help get you into the research literature. These limiters will be located in different places depending on the database, but often they are to the left of the results.
