Data Analyst Job Profile

What is a Data Analyst?

Data Analysts determine how to use data to answer questions and solve problems. They examine current events in order to identify trends and forecast the future. They’re like detectives, figuring out how things work and making sense of it all. It can be a rewarding, creative, and challenging career.

Analytics combines theory and practice to identify and communicate data-driven insights that enable managers, stakeholders, and other executives to make more informed decisions in an organisation. Experienced Data Analysts consider their work in the context of their organisation as well as various external factors. Analysts can also account for the competitive environment, internal and external business interests, and the absence of specific data sets in data-driven recommendations to stakeholders.

There are four types of data analytics that build on one another to provide increased value to a company. These are:

  • Descriptive analytics looks at what happened in the past, such as monthly revenue, quarterly sales, and yearly website traffic. These kinds of findings enable a company to identify trends.
  • Diagnostic analytics investigates why something occurred by comparing descriptive data sets in order to identify dependencies and patterns. This assists a company in determining the root cause of a positive or negative outcome.
  • Predictive analytics attempts to predict likely outcomes by detecting trends in descriptive and diagnostic analyses. This enables an organisation to take proactive action, such as reaching out to a customer who is unlikely to renew a contract.
  • Prescriptive analytics seeks to determine the best course of action for a business. While this type of analysis is extremely valuable in terms of addressing potential problems or staying ahead of industry trends, it frequently necessitates the use of complex algorithms and advanced technology such as machine learning.

Organisations across all industries are increasingly relying on data to make critical business decisions, such as which new products to develop, which markets to enter, which investments to make, and which new (or existing) customers to target. Data is also used to identify inefficiencies and other business issues that must be addressed. The Data Analyst’s job in these organisations is to assign a numerical value to these critical business functions so that performance can be assessed and compared over time. However, the job entails more than just looking at numbers: a Data Analyst must also understand how to use data to help an organisation make more informed decisions.


On a daily basis, many Data Analysts have the following responsibilities:

  • Data collection: Data Analysts frequently collect data on their own. Conducting surveys, tracking visitor characteristics on a company website, or purchasing datasets from data collection specialists could all fall under this category.
  • Data cleaning: Raw data may contain duplicates, errors, or outliers. Cleaning the data entails keeping the quality of data in a spreadsheet or programming language so that your interpretations are not incorrect or skewed.
  • Modelling data: This entails creating and designing database structures. You might decide what types of data to store and collect, how data categories are related to one another, and how the data will appear.
  • Data interpretation: Identifying patterns or trends in data that will assist you in answering the question at hand.
  • Presenting: Communicating the findings of your research will be an important part of your job. You accomplish this by creating visualisations such as charts and graphs, writing reports, and presenting information to interested parties.
  • Collaborating with programmers, engineers, and organisational leaders to identify process improvement opportunities, recommend system changes, and develop data governance policies.


The national average salary for a Data Analyst in the UK is £32,899. Ranging from £22,000 to £ 50,000. With average additional compensations amounting to £2,138.

Working hours and work location 

Most Data Analysts work in groups, and the majority of their work is done on a computer. Much of the work can be done from home or a remote office, depending on the type of data being gathered. Data Analysts can usually expect to work regular hours, but important projects or approaching deadlines may necessitate some overtime and weekend work.

Data Analysts They work in a variety of fields such as:

  • Business
  • Finance
  • Criminal justice
  • Science
  • Medicine
  • Government.

What to expect

Data Analysts typically use computer systems and calculation applications.  Facts and numbers are the starting point, but understanding what they mean and presenting the findings in an interesting way, using graphs, charts, tables, and graphics, is more important. Data Analysts must be able to not only decipher data but also report and explain what differences in numbers mean when compared year to year or across departments. Because Data Analysts frequently have the best understanding of why the numbers are the way they are, they are frequently asked to advise project managers and department heads on specific data points and how they can be changed or improved over time.

The analysis of data typically proceeds through five iterative stages:

  • Determine which data you want to examine.
  • Collect the information
  • Clean the data before analysing it.
  • Examine the data
  • Interpret the analysis results

Data Analysts frequently use a wide range of tools to improve the accuracy and efficiency of their work during the data analysis process. The following are some of the most commonly used tools in the data analytics industry:

  • Microsoft Excel
  • Google Sheets
  • SQL
  • Tableau
  • R or Python
  • SAS
  • Microsoft Power BI
  • Jupyter Notebooks


Most entry-level Data Analyst positions require a bachelor’s degree or higher. Data analysis, mathematics, finance, economics, and computer science are all possible areas of study. A master’s degree in data analysis, data science, IT  or business could lead to new and better-paying job opportunities.

Almost every industry has a need for Data Analysts; the fields of sales, marketing, and healthcare typically have the most jobs available at any given time. Many Data Analysts progress to become data scientists. Data scientists, like Data Analysts, analyse data using statistics, maths, and computer science. A scientist, on the other hand, may use advanced techniques to create models and other tools that provide insight into future trends.

People who analyse data may hold additional titles such as:

  • Medical and health care analyst
  • Market research analyst
