A Data Analyst collects, cleans, and interprets data sets in order to answer a question or solve a problem.
They work in many industries, including business, finance, criminal justice, science, medicine, and government.
What is data analysis?
Data analysis is the process of gleaning insights from data to inform better business decisions.
The process of analyzing data typically moves through five iterative phases:
👉Identify the data you want to analyze
Collect the data
👉Clean the data in preparation for analysis
👉Analyze the data
👉Interpret the results of the analysis
A Data Analyst is a person whose job is to gather and interpret data in order to solve a specific problem.
The role includes plenty of time spent with data but entails communicating findings too.
Here’s what many data analysts do on a day-to-day basis:
👉Gather data: Analysts often collect data themselves. This could include conducting surveys, tracking visitor characteristics on a company website, or buying datasets from data collection specialists.
👉Clean data: Raw data might contain duplicates, errors, or outliers. Cleaning the data means maintaining the quality of data in a spreadsheet or through a programming language so that your interpretations won’t be wrong or skewed.
👉Model data: This entails creating and designing the structures of a database. You might choose what types of data to store and collect, establish how data categories are related to each other, and work through how the data actually appears.
👉Interpret data: Interpreting data will involve finding patterns or trends in data that could answer the question at hand.
👉Present: Communicating the results of your findings will be a key part of your job. You do this by putting together visualizations like charts and graphs, writing reports, and presenting information to interested parties.
