Who Is a Junior Data Analyst?

A Junior Data Analyst is an entry-level professional who supports senior analysts, business teams, and stakeholders by collecting, cleaning, analysing, and reporting data. Their primary goal is to transform raw data into meaningful insights that help organisations improve performance, optimize operations, and make informed decisions.

Junior Data Analysts typically work in industries such as technology, finance, healthcare, e-commerce, consulting, and operations, where data plays a critical role in tracking performance and identifying trends.

Key Roles & Responsibilities of a Junior Data Analyst

1. Data Collection and Preparation

  • Cleaning datasets by removing duplicates, fixing errors, and handling missing values

Clean and accurate data is the foundation of reliable insights.

2. Data Analysis and Interpretation

Junior Data Analysts analyse datasets to identify:

A key part of the role is turning analysis into easy-to-understand reports. Junior Data Analysts often:
