In an era that is increasingly reliant on data and collecting statistics and data analytics, it is essential that individuals and organizations make sure their data is working for them. Utilizing a variety of tools and techniques, a set of raw numbers can be converted into useful and educational insights that guide decision-making and intelligent management.

Data analysis is the systematic analysis and interpretation of data sets in order to identify meaningful patterns, trends, and patterns. These patterns are used as the basis for business decision-making and to improve performance. It also entails communicating the results of these analyses to stakeholders and other staff members within the company.

To make a data analysis efficient, it should start with a clearly defined goal and end with actionable, concrete suggestions to the company. This will ensure the work is targeted and efficiently translated into real-world business impact. Netflix viewing recommendations are one example. They are based upon extensive data collected on what people watch, when they watch it and how much they enjoy particular type of content. This has resulted in personalized recommendations that have a major impact on the habits of viewers, resulting in higher revenue for Netflix.

Once a business question or issue is clearly identified, it’s time to collect data. This typically involves pulling structured data either from internal sources such as CRM, or from external sources like government records and APIs for social media. The data is cleaned prior to analysis. This may include removing duplicate or anomalous entries as well as reconciling inconsistencies, standardizing data structure and format, and dealing with white spaces and syntax errors.
