What Is Statistical Analysis? Definition, Types, And Jobs

Statistical analysis is a rapidly growing career with a wide range of benefits. It is an important tool when it comes to making smart informative decisions based on data. With the help of statistical analysis we can easily know people’s preferences, what might happen in the market, understand the behavior of people, and more.

In this blog, we will learn how to do statistical analysis in the same way. We will learn about different types, tools, and working of statistical analysis.

What is Statistical Analysis?

Statistical analysis is collecting, organising, interpreting, and presenting data to discover trending patterns, trends, relationships, and make informed decisions based on data.

Statistical Analysis

It involves mathematical tools and techniques to understand what the data is telling us. For example, you might use statistical analysis to find out the average age of customers, the correlation between hours studied and exam scores.

Why Is Statistical Analysis Important?

Statistical analytics is used to make informed decisions based on raw data. It helps in making informed decisions and predicting market trends. It is useful for market research, financial forecasting, risk management, and customer behavior analysis.

With statistical analytics we can easily uncover hidden trends, relationships and patterns existing in datasets which can be crucial for planning and forecasting. You can easily eliminate risks by analysing available data and making informed decisions which can promote growth of the business.

Is Data Analysis and Statistical AnalyticsS Same?

Statistical Analysis

Data analysis and statistical analysis are not the same and share some major differences which must be taken into account.

Data Analysis

Data analysis is a complete overall term of inspecting, cleaning, transforming, and modeling data to extract useful insights from the data and help in making informed decisions. It uses various methods apart from statistics to operate on data for information.

Statistical Analysis

Statistical analysis is a part of data analysis which usually focuses on using mathematical techniques such as regression, hypothesis, mean, median, average, and more to understand data and extract useful insights from it. It is more based on statistics, probability and prediction.

Types of Statistical Analysis Techniques

Statistical Analysis

There are two main types of statistical analysis methods which are frequently used in analysing data. Let us find more about them below.

1. Descriptive Statistical Analytics

Descriptive Statistical analysis is used to organise raw data and summarize them in a user-friendly manner which can easily be recognised and understood. It describes the basic features of a dataset by using methods like mean, median, mode, range, standard deviation, and other tools such as charts and graphs.

The main goal of descriptive statistical analytics is used to represent an overview or snapshot of the data. For example, when you are calculating the average test score of a class gives a general idea of overall performance.

2. Inferential Statistical Analysis

The inferential statistical analysis deals with describing important information about data used to make predictions about a larger population or data based on sample. The methods include correlation, regression, confidence intervals, hypothesis testing, and probability distribution, and more.

3. Predictive Modeling

Predictive modeling is a statistical method working based on machine learning and statistical algorithm techniques. It is used to predict the possible future outcomes based on available or historical data. It is widely popular among various fields such as healthcare, weather forecasting, marketing, finance, and more.

They train historical data to identify relations and patterns among variables which can be used to make predictions on unseen information and data. The common techniques of predictive modeling are linear regression, decision trees, neural networks and support vector machines.

4. Prescriptive Analysis

Prescriptive analysis is used to recommend favorable actions to businesses or organisations after receiving the predictions from the predictive models. It involves decision making to achieve objectives set by an organisation.

It analyses multiple future scenarios, weighs different options, and advises the best course of action based on various preferences set by the organisation. For example, a prescriptive model can suggest optimal discount rate for each product to maximize the profits while minimising the inventory costs.

5. Exploratory Data Analysis (EDA)

The Exploratory Data Analysis (EDA) is used to analyse datasets to summarize their main characteristics. It helps data scientists and analysts to get the knowledge of data and uncover insights, relationships, and issues that can affect analysis moving ahead.

Features of Statistical Analysis

Check some of the features of statistical analysis below.

1. Data Collection

Statistical analysis begins with the collection of raw data from various sources such as surveys, experiments, sensors, or databases. Accurate and relevant data collection ensures that the analysis reflects real-world conditions and forms the foundation for drawing reliable conclusions.

2. Data Organization

After we complete data collection then the data is organised in a complete structured format such as spreadsheets, charts, tables and more. This helps in popper analysis of the extracted data and easy interpretation.

3. Data Summarization

This involves using measures like mean, median, mode, variance, and more to give a complete overview of the data. It simplifies the complex data into usable insights allowing for important decision making.

4. Data Interpretation

This feature focuses on taking out conclusions from the data analysed which involves understanding the complete statistical results about the real world problems.

5. Hypothesis testing

After data interpretation the complete focus shifts on detecting patterns, correlations, behavior analysis and trends within the data. It uses hypothesis testing which allows for formal testing of assumptions about data using various techniques like Chi-square tests, ANOVA, T-tests, and more.

6. Forecasting & Predictions

The collected data is analysed and then used for forecasting about future trends or values such as sales forecasting, stock market analysis, weather predictions, and more.

7. Anomaly Detection

It is important to find outliers or anomalies in the data such as potential fraud, rare events, errors, and more. Statistical analysis can help in finding out the outliers in the data which is very important in finance, cybersecurity, and quality control.

Roles of Statistical Analysis

Statistical Analysis

Statistical analysis makes use of mathematical formulas and techniques to make the raw available data understandable for the general public. With this you can use charts, graphs, and more methods to present key results for better decision making.

1. Data Summarization

Statistical analysis is used to simplify extensive & large volumes of data into meaningful summaries using methods like averages, percentages, and distributions. This helps users quickly grasp essential information present in the data.

2. Decision Making

It supports evidence-based decision-making by providing insights from data. Businesses, governments, and researchers use statistical evidence to choose the best course of action for a certain specific condition.

3. Identifying Patterns and Trends

Statistical tools in data analysis are used to uncover patterns, trends, and correlations in data, which are essential for forecasting, planning, and strategy development.

4. Hypothesis Testing

It allows for the validation or rejection of assumptions through formal tests, making research results more credible and reducing the risk of incorrect conclusions.

5. Process Optimization

Statistical analysis is used in quality control and operational efficiency, helping organizations reduce waste and improve consistency in industries and manufacturing.

6. Risk Assessment and Management

Statistical models help evaluate and predict risks and uncertainties, which is crucial in finance, healthcare, insurance, and project management.

7. Scientific and Academic Research

Statistical analysis is foundational in research for drawing reliable conclusions, publishing findings, and ensuring results are valid, reproducible, and significant.
