Updated · Jul 19, 2022
Data sets are the bread and butter of data analysts. If you’ve ever conducted analytical research with several variables, then you’re aware of just how vital they are. So, where to find data sets when conducting research?
Fortunately, numerous online platforms host and provide data set services. Let’s explore several repositories and dig into data sets some more.
What is a Data Set?
Simply put, it's a collection of particular information.
Excel data sets primarily come in tabular form. There are usually variables representing different facets of a phenomenon. An example is tabularized details on the distribution locations of a product or service based on different criteria such as an age group.
In other words, it consists of variables and corresponding values. The best way to create it is to use a module or data package. Today, there are several software packages that you can employ to create a data store.
The first step is to collect the information. Depending on the area of study or interest, several methods are used, such as:
- Online survey forms
- Case management systems
- Data registries
- Report systems.
CSV data sets generally consist of rows, integers, and columns of open data. Analysts often use data visualization software, like SPSS to unwrap the inner secrets of each set. This tool analyzes numerical data sets with unique algorithms while ensuring the effective presentation of your results.
Where to Find Data Sets?
Data sets aren't as challenging to find as you can imagine. Many agencies and private organizations store vast amounts of information. Over the past years, more and more have gone public - offering sets for free. An excellent example of this is when Amazon made its database accessible in the Open Registry.
Many databases are available online. Stored digitally in different formats, including CSV, students and researchers can download them for use.
Let’s take a look at the top-ten repositories for free data sets.
