Are you looking for EDA Tools that can help you with your projects and data collection?
Exploratory data analysis (EDA) is a technique used to evaluate and investigate data sets, generally by applying data visualisation tools. The primary goal of these Exploratory Data Analysis tools is to help in the examination of data prior to forming any assumptions. It can assist in identifying obvious errors as well as in patterns within the related data, identifying outliers or unusual events, and discovering interesting relationships between the variables.
Here you will get to know about tools based on programming as well as Non-programming criteria in order to provide you with a better learning experience.
Tools for Programmers
Programming tools can be used to perform EDA on a data collection in order to identify the missing value in it. Other functions that can be carried out include: the description of data, the handling of outliers, and the extraction of insights from charts. These tools are:
- Python:
Identifying any missing value in a data set can be accomplished by using Python. Data description, addressing outliers, and gaining insights through plotting are other functions that the program may perform modelling. High-level data structures and dynamic typing and binding make it an appealing tool for Exploratory Data Analysis (EDA. Python includes several open-source modules that can automate the entire EDA process and save time for developers.
- R:
The R programming language is frequently used by data scientists and statisticians to develop statistical measurements and analyse large amounts of data.
Tools for non-programmers
Non Programming tools for EDA provides access to all of the essential features, such as summarising data, visualising data, data wrangling, and so on, and is powerful enough to examine data from all imaginable perspectives. These tools are:
1. Microsoft Excel / Spreadsheet
Excel and data analytics are two terms that come to mind. When it comes to data science, whether you are just starting or have been doing it for years, you should be aware that, even after numerous years, Excel remains an essential aspect of the analytics industry. Even today, this software is still being used to tackle most of the difficulties that arise in analytics initiatives. Learning this technology has gotten significantly easier, thanks to a larger than ever community of support, tutorials, and free resources.
2. Trifacta
Trifacta’s Wrangler data cleaning and manipulation tools are upending standard data cleaning and manipulation methods. Unlike Excel, which has data size limitations, this tool does not have such restrictions, allowing you to work securely with large data sets. You can make reports in no time, non-programmers thanks to the wonderful features of this application, which include chart recommendations, inbuilt algorithms, and analysis insights. It is a tool focused on addressing business problems more quickly, helping us be more productive when working with data.
3. Rattle the GUI with the R key
Rattle gives a sufficient number of tools for exploring, transforming, and modelling data in a matter of clicks. However, when it comes to statistical analysis, it has fewer possibilities than SPSS. Although SPSS is a commercial product, Rattle is completely free.
4. Qlikview
QlikView is a business intelligence tool. It is one of the most widely used business intelligence tools globally, and it is used by companies worldwide. This tool’s primary function is to extract business insights and show them visually appealing. Thanks to its state-of-the-art visualisation features when working with data, you’ll be shocked by how much control you have. While working with data sets, it features an inbuilt recommendation engine that keeps you up to date on the latest and greatest visualisation techniques available.
EDA Charts
A variety of alternative charts can be used, based on the properties of your data. For example:
- Line charts are used to demonstrate changes over time.
- Pie charts are used to illustrate the relationship between a part and the whole.
- Maps are used to visualise geographic information.
Conclusion
Exploratory Data analysis summarises large data sets because it ensures that you have the correct data for the statistical model you have chosen. You would surely not want to discover at a later point that the data you have collected does not correspond to the statistical model you are attempting to construct. Before any data analysis, research methodology, or data modelling can occur, it is necessary to do a thorough EDA by using various tools.
