what is a data scientist?
More than ever, companies, governments and other institutions rely on data to make decisions. This data can track traffic flows, consumer purchasing habits and weather patterns. Raw data doesn't help decision-makers choose the best options; someone has to process and analyse it. This task falls to data scientists as expert analysts with deep knowledge of technology and statistics.
Data scientists combine analytical skills with knowledge of the topic they're analysing to create models based on their study data. As a data scientist, you use these models to understand past and present situations and predict future behaviour.
what do data scientists do?
Like all scientists, data scientists conduct analyses and present their findings to stakeholders. Communication skills are a vital part of your job as a data scientist. You provide clear, useful information when communicating with corporate management, the government or the public.
As a data scientist, your knowledge benefits government institutions and non-government organisations that sponsor research in various fields. Some data scientists work in the healthcare, pharmaceutical and chemical industries. You can also work for mining, automobile and meteorology companies. You contribute to agriculture and mining by predicting natural disasters and other events that affect these sectors.
view opportunitiesaverage salary of a data scientist
Due to the rising demand for data scientists, the remuneration package is usually competitive, even for beginners. The average remuneration for data scientists in New Zealand is $150,000 annually. At entry-level, joining the field with minimal experience, your starting salary is $140,000 per year. The amount increases as you build your skills or specialise in specific sectors. An experienced data scientist takes home over $170,000 per year. The remuneration package includes annual leave days and paid sick days, among other benefits.
what factors affect the salary of a data scientist
The salary of a data scientist is based on expertise and qualifications. Entry-level data scientists are likely to earn less due to their minimal experience. When you have additional qualifications, your earnings increase steadily. The size of the project and the funding also influences your salary. Some projects have limited resources and pay less than large projects with higher budgets.
Working for the private sector also increases your remuneration prospects compared to working for the government. Evaluate the monetary and non-monetary benefits you are likely to receive before signing a contract.
types of data scientists
In the world of data science, you can pursue different specialisations. These include:
- data engineering: as a data engineer, you build and maintain the frameworks used for analysis by consolidating, cleaning and structuring data collected from multiple sources.
- database management and architecture: a step up from a data engineer, this specialist is responsible for designing an organisation's digital framework.
- operations data analysis: as an operations data analyst, you work in a less technical role using statistical software to evaluate and solve business-specific problems.
- marketing data analysis: as a marketing data analyst, you are concerned with measuring and improving the effectiveness of a marketing campaign, particularly in terms of ROI and considering marketing trends.
- machine learning: machine learning is a growing field within data science. Data scientists specialising in machine learning create algorithms without direct human participation. These automated systems can operate many times faster than humans, making them ideal for large data sets.
- artificial intelligence: artificial intelligence (AI) is another specialisation area within data science. Although related to machine learning, AI has its methods and principles, and many data scientists specialise in one or the other.

data scientist duties and responsibilities
As a data scientist, your daily work activities include:
- synthesising and analysing data: as a data scientist, you collect data from different sources in the company and analyse it. You collect data from various software programs and other business intelligence dashboards.
- developing forecast models: as a data scientist, you determine the statistical and analytical tools used to evaluate data in an organisation. You create predictive models and forecasts based on the information stipulated by the company.
- proposing hypotheses: from the initial data analysis, you present a hypothesis that solves a specific business problem. You use the hypothesis as the basis of your research, and your analysis focuses on validating it for key decision-makers in the company.
- identifying data and analysis needs: as a data scientist, you identify the valuable data that a business needs to drive research and improve business growth. You can develop data models for collecting information from business intelligence needs. You also design metrics for tracking and measuring business performance.
- building new models and analytical tools: as a business grows and develops new products, it requires new predictive models to aid its growth. Your job is to develop the models and help the company collect information on consumer reactions to its products.
-
work environment
As a data scientist, you typically work in an office environment. You conduct most of your analysis using computers and other information technology. Your job may involve travelling to meetings or conferences, but regular travel is uncommon. You may not even work in a traditional office. Increasingly, many data scientists work remotely, either going into an office occasionally or working entirely online.
-
who are your colleagues?
Depending on your employer and the industry you work in, your colleagues might include researchers, data analysts, data engineers, chemical engineers and economists. You might also be working in close proximity to clinical doctors and nutritionists, as well as other specialists that could include, but not be limited to, office managers, project managers, research scientists and technical writers.
-
work schedule
The work schedule of a data scientist is relatively predictable. Most of the time, you work standard office hours on weekdays; late hours or weekend work are rare. However, flexibility in working hours is an expected part of the job. Delivering reports or similar publications is integral to many data scientists' roles, and late hours may be necessary when a deadline approaches. On average, you work between 37 and 39 hours a week.
-
job outlook
Your career as a data scientist offers excellent prospects for advancement. In addition to going deeper into data science through experience and postgraduate study, you can move into other fields. You could specialise in data sciences like artificial intelligence or machine learning. If you enjoy working with large teams of data scientists, consider moving into a management role. If you're more focused on the science side of your work, entering academia as a researcher or lecturer may be for you.
