4 Top Data Scientist Skills to be Successful

-
Data science is a combination of technical and general skills. As an analyst, you are responsible to provide useful information to the client. Below is a useful list of skills.

Top Data Scientist Skills.


4 Important Skills You Need for Data Scientists

1. Paradigms and practices.

This involves data scientists acquiring a grounding in core concepts of data science, analytics, and data management. 

Data scientists should easily grasp the data science life cycle, know their typical roles and responsibilities in every phase, and be able to work in teams and with business domain experts and stakeholders. 

Also, they should learn a standard approach for establishing, managing, and operationalizing data science projects in the business.

2. Algorithms and modeling.

Here are the areas with which data scientists must become familiar:
  • linear algebra, 
  • basic statistics, 
  • linear and logistic regression, 
  • data mining, 
  • predictive modeling, 
  • cluster analysis, 
  • association rules, 
  • market-basket analysis, 
  • decision trees, 
  • time-series analysis, 
  • forecasting, machine learning, 
  • Bayesian and Monte Carlo Statistics, 
  • matrix operations, 
  • sampling, 
  • text analytics, 
  • summarization, 
  • classification, 
  • primary components analysis, 
  • experimental design and unsupervised learning-constrained optimization.

3. Tools and platforms

Data scientists should master a basic group of modeling, development, and visualization tools used on your data science projects, as well as the platforms used for storage, execution, integration, and governance of big data in your organization.


Depending on your environment, and the extent to which data scientists work with both structured and unstructured data, this may involve some combination of : 

  • data warehousing, Hadoop, stream computing, NoSQL, and other platforms. 
  • It will probably also entail providing instruction in MapReduce, R, and other new open-source development languages in addition to SPSS, SAS, and any other established tools.

4. Applications and outcomes.

A major imperative for data scientists is to learn the chief business applications of data science in your organization, as well as ways to work best with subject-matter experts: 
  • In many companies, data science focuses on marketing, customer service, the next-best offer, and other customer-centric applications. 
  • Often, these applications require that data scientists know how to leverage customer data acquired from structured survey tools, sentiment analysis software, social media monitoring tools, and other sources. 
  • Plus, every data scientist must understand the key business outcomes—such as maximizing customer lifetime value—that should be the focus of their modeling initiatives.

SQL Query: 3 Methods for Calculating Cumulative SUM

-
Image
SQL provides various constructs for calculating cumulative sums, offering flexibility and efficiency in data analysis. In this article, we explore three distinct SQL queries that facilitate the computation of cumulative sums. Each query leverages different SQL constructs to achieve the desired outcome, catering to diverse analytical needs and preferences. Using Window Functions (e.g., PostgreSQL, SQL Server, Oracle) SELECT id, value, SUM(value) OVER (ORDER BY id) AS cumulative_sum  FROM your_table; This query uses the SUM() window function with the OVER clause to calculate the cumulative sum of the value column ordered by the id column. Using Subqueries (e.g., MySQL, SQLite): SELECT t1.id, t1.value, SUM(t2.value) AS cumulative_sum FROM your_table t1 JOIN your_table t2 ON t1.id >= t2.id GROUP BY t1.id, t1.value ORDER BY t1.id; This query uses a self-join to calculate the cumulative sum. It joins the table with itself, matching rows where the id in the first table is greater than...

5 SQL Queries That Popularly Used in Data Analysis

-
Image
 Here are five popular SQL queries frequently used in data analysis. 1. SELECT with Aggregations Summarize data by calculating aggregates like counts, sums, averages, etc. SELECT department, COUNT(*) as employee_count, AVG(salary) as average_salary FROM employees GROUP BY department; 2. JOIN Operations  Combine data from multiple tables based on a related column. SELECT e.employee_id, e.name, d.department_name FROM employees e JOIN departments d ON e.department_id = d.department_id; 3. WHERE Clause for Filtering Filter records based on specified conditions. SELECT * FROM sales WHERE sale_date BETWEEN '2024-01-01' AND '2024-12-31'   AND amount > 1000; 4. ORDER BY Clause for Sorting Sort results in ascending or descending order based on one or more columns. SELECT product_name, price FROM products ORDER BY price DESC; 5. GROUP BY with HAVING Clause Group records and apply conditions to the aggregated results. SELECT department, SUM(salary) as total_salaries FROM employ...
