# Different Types of Statistical Analysis: An Important Guide For Students

Businesses and organizations use statistical analysis to understand the data. It helps them in their decision-making. Statistical analysis techniques come in a variety of forms. They are used on a wide range of data, sectors, and applications. Understanding the types of statistical analysis tools and how to use them will assist you in exploring data, identifying patterns, and identifying trends in your industry. Different statistical ideas may be easily applied to real life. Such as predicting the time, calculating the amount of money, calculating the cost of schooling, etc. That is why students need to understand the types of statistical analysis.

Thus, here we will discuss the types of statistical analysis. So, let’s begin our discussion with an overview of statistical analysis.

**What Is Statistical Analysis?**

It is a technique for collecting, analyzing, and representing large amounts of data to look for trends and patterns. Statistics are used in companies, research, and government. It is also used to carry out scientific study. Then evaluate the results of that investigation. Following are the examples of statistical analysis. Let’s have a look:

- Many researchers apply statistical analysis to keep children healthy. They examine data from infectious disease vaccines and confirm the safety and reliability of the vaccines.
- Designers use data to generate high-quality designs. It increases fabric beauty and provides the airline industry with a boost. It also benefits guitarists in making lovely musical sounds.

**Types Of Statistical Analysis**

There are several different types of statistical analysis. They are as follows;

**Descriptive Analysis**

Descriptive statistical analysis assists in the description of data. It creates a data summary. So that it may be analyzed for useful information. We do not come to a conclusion using descriptive analysis. But we do understand what is in the data.

There are two types of descriptive analysis used to describe data:

- Central tendency measures
- The measure of variance

**Prescriptive Analysis**

It works on the data by asking this question. A common area of business analysis is choosing the best course of action in a given circumstance. Its entire goal is to give the greatest suggestion for a decision-making process.

The prescriptive analysis employs a variety of methodologies. It includes simulation, business law, graph analysis, algorithms, machine learning, etc.

**Predictive Analysis**

A method for predicting future events is predictive analysis. It is founded on both current and historical data. Based on past and fresh data, it uses statistical algorithms and machine learning tools. It is used to predict future events, trends, and behaviors. In business, predictive analytics is utilized to obtain a competitive advantage. It lessens the risk of an uncertain future.

Predictive analysis is most commonly used in marketing, financial services, internet service providers, and insurance companies. The predictive analysis employs techniques. Such as simulation, data mining, artificial intelligence, and others.

**Causal Analysis**

Everyone wants to know why the question “WHY” is asked. Why is it that certain things are happening in a certain way? As a result, casual analysis assists in understanding WHY things happen the way they do. The causal analysis identifies the actual issue of events. This method is widely used in the IT sector. It enables them to get knowledge about the software’s quality assurance.

**Exploratory Data Analysis**

Data scientists mostly use this type of inferential statistics. It focuses on identifying patterns and figuring out unknown correlations. Missing data is identified, unknown relationships are discovered, and hypotheses and assumptions are developed using exploratory data analysis.

**Mechanistic Analysis**

The mechanistic analysis is significant in major enterprises. It is used to determine how changes in one variable influence the other variables. It is helpful in a system with well-defined terminologies, such as biology.

**BONUS POINT**

**What are the four most basic statistical analysis methods?**

The following are some of the most common statistical analysis approaches:

**Mean**

By summing the numbers in the lists and dividing the result by the number of items, you may get the mean. It is the most basic type of statistical analysis. It helps the user to find the data set’s center point. The formula of the mean is as follows:

Mean = Sum of numbers/ Numbers of items in the set

**Standard Deviation**

The standard deviation is used to assess how data points are distributed. It is a statistical analysis technique. It figures out how data spread around the mean. The data spread significantly from the mean is referred to as standard deviation. When the standard deviation is low, it suggests that the majority of the data is near to the mean. The formula of standard deviation is;

**σ2 = Σ(x − μ)2/n**

**Regression**

It is a statistical strategy. It finds out the connection between dependent and independent variables. Regression is a technique for determining how changes in one variable impact another. It can indicate if the correlations between the two variables are weak, strong, or change over time. The formula of regression is as follows:

Y=a+b(x)

**Hypothesis Testing**

It compares the data to the particular assumption to see if the conclusion is true or not. The hypothesis can nullify the test result, which is known as the null hypothesis or hypothesis 0. The first hypothesis is generally known as hypothesis 1. It is anything that contradicts the null hypothesis.

**Conclusion**

So, to conclude, we have discussed the different types of statistical analysis. We have also learned the different types of statistical analysis methods. As we all know, statistics is a difficult subject. It is challenging for a several students. But if you try hard and practice, you can achieve anything. So, in the end, I hope this blog on types of statistical analysis helps you.
