What is Statistics?

Statistics, a vital part of math, helps us understand data better. It's not just math tricks; it's a way to make sense of complex data. The journey starts by collecting info from places like surveys or experiments. This is where statistical insight begins, setting the stage for what's next. The next step is organizing the data, where statisticians arrange info, turning it from numbers into a clear dataset.

 Armed with different math models, statistics then goes on an analytical adventure, searching for patterns and trends. By measuring connections between factors, statisticians unveil insights for predictions and decisions. The interpretative side of statistics acts as a bridge between raw data and practical knowledge. Here, statisticians decode meanings, turning complex results into understandable stories.

Key Concepts Used in Statistics:

  1. Mean
  2. Median
  3. Mode
  4. Standard deviation (σ)
  5. Variance (σ²)
  6. Techniques: Probability distribution, acceptance sampling, statistical quality control

Application Areas of Statistics:

  1. Medical

Data Science vs Statistics: Major Differences between Data Science and Statistics

 

ComponentsData ScienceStatistics
Concepts

Data science operates proficiently on both qualitative and quantitative data, especially in the context of big data. The primary focus is on identifying underlying trends and patterns, involving a comprehensive process that includes data collection, pre-processing, exploratory data analysis, model building, and optimization. Techniques encompass a broad spectrum, including regression, classification, and the utilization of diverse machine learning algorithms.

Statistics adopts a purely mathematical approach, dissecting smaller, more manageable sampled data to unravel cause-and-effect relationships. It primarily deals with quantitative data, employing terms such as mean, median, mode, standard deviation, and variance for nuanced data comparison. The methods include probability distribution, acceptance sampling, and statistical quality control.

Application Areas

Data science extends its applications beyond statistics, venturing into specialized fields like computer vision, natural language processing, disaster management, recommender systems, and search engines. Its versatility allows for addressing complex challenges in various domains, including healthcare, aviation, manufacturing, and transportation.

Statistics finds applications in sectors where random variations in sampled data are prevalent. These sectors include medical, information technology, economics, engineering, finance, marketing, accounting, and business. The precision of statistics allows for accurate predictions for a larger population based on sampled data.

Approach

Data science embraces a more exploratory approach, identifying the best modeling technique by evaluating predicted accuracy. Data scientists engage in comparing the accuracy of multiple machine learning models before selecting the most effective one. The emphasis is on building and fine-tuning models on pre-processed datasets, ensuring efficacy in real-world scenarios.

Statistical analysis often commences with a simple model, such as linear regression, assessing the consistency of the data against the model hypothesis. The focus is on building a single model that best fits the data, incorporating both descriptive and inferential statistical approaches.

 

Career Options

The field of data science offers a spectrum of clearly defined roles with tasks varying based on qualifications and experience. Roles include data scientist, data analyst, data architect, data engineer, and database manager. The demand for data science degree holders has surged, with average salaries ranging from 7.2 LPA for entry-level positions to 12 LPA for senior professionals.

Statistics presents a diverse array of roles, including market researchers, financial analysts, business analysts, economists, and database administrators. However, there's no rigid hierarchy, and roles can vary across organizations. Statistician roles have consistently been in demand globally, with salaries ranging from 5.6 LPA.

Skill Sets and Tools

Data scientists require a degree in data science or a related field, coupled with a strong understanding of algorithms. Proficiency in programming languages like Python, R, C/C++, and Java is crucial, along with analytical skills. Soft skills such as teamwork, communication, organization, and problem-solving are also essential for a holistic skill set.

Professionals in statistics need a degree in statistics or mathematics, showcasing advanced mathematical skills in calculus, linear algebra, and probability. Fluency in tools like Excel, SAS, SPSS, and Minitab is essential, along with a basic knowledge of Python for statistical analysis. Strong communication and planning skills are also prerequisites for success in the statistical profession.

Real-World Applications

Data science manifests in impactful real-world applications, such as healthcare for predicting dangerous illnesses, computer vision for real-time object identification, and retail and e-commerce for customer personalization. Its reach extends to banking and finance for fraud detection, aviation for flight route planning, and manufacturing for predictive maintenance.

Statistics finds practical utility in areas like the stock market for determining dynamically changing stock values, weather forecasting for accurate predictions using probability concepts, and sports for comparing circumstances and making decisions during games. It permeates research, public administration, business, consumer goods, insurance, and disaster prevention.
