The majority of pupils still can’t tell the difference between probability and statistics. Probability and statistics are two topics of mathematics that are closely related. They are used to investigate the relative frequency of events. However, there is a significant distinction between probability and statistics. Let’s begin with a simple comparison.

Probability is concerned with forecasting future events. Statistics, on the other hand, are also used to examine the frequency of historical events. Another distinction is that probability is a theoretical area of mathematics, whereas statistics is an applied branch.

For math students, both of these courses are essential, relevant, and beneficial. However, as a math student, you should be aware that they are not synonymous. They may share many characteristics, but they are still distinct individuals.


You should notice the difference because it will aid you in appropriately interpreting the significance of mathematical data. Many students and mathematicians fail because they are unable to understand the distinction between probability and statistics. Let’s look at the differences based on the following criteria:-


Statistics vs. Probability




Probability Definition


It is a field of mathematics that studies the random occurrences that will occur in an event. It is impossible to predict the outcome before the event occurs. However, there are always multiple outcomes.


The study of real outcomes is what probability is all about. It’s somewhere between 0 and 1. The numbers 0 and 1 represent impossibility and certainty, respectively. The closer the probability number is to one, the more likely the event will occur.


Statistics Definition


Statistics is a mathematical discipline. For a given collection of experimental data, it employs quantified models and representations. There are numerous approaches in statistics for gathering, reviewing, analyzing, and drawing conclusions from any set of data.


To put it another way, it summarizes a technique utilized by the analyst to characterize the data set. Statistics analysis is used by statisticians to collect and evaluate data. It can also be used to convert data into a mathematical representation.




Probability Example


When it comes to probability, mathematicians would look at the dice and wonder, “Six-sided dice? They will also receive a projection of where the dice will most likely land, with each face facing up equally. After then, they’ll suppose that each face will have a chance of 16%.


Statistical illustration


The statistician, on the other hand, will use the same dice scenario but with different assumptions. In this situation, the mathematicians will look at the dice and wonder, “Those dice appear to be in good shape, but how do I know they aren’t loaded?”


He’ll do this by watching for a while and keeping track of how often each number appears. Then he’ll assess if the observations are consistent with the equal-probability face assumption. Once he has enough faith in the fairness of the dice.




Different types of probability


There are four major forms of probability.


Probability theory


It’s the very first probability method. We frequently utilize coin tossing and dice rolling in this method. We arrive at our conclusions by noting all possible outcomes of the activity as well as the actual events.


Let’s use the example of tossing a coin to better comprehend it. Then there will always be only two possible outcomes: heads or tails. If you throw the same coin 10 times, you’ll get 20 different results, and you’ll keep track of each one.


Probability in Experiments


It differs from the recent one in that the experimental probability is calculated by dividing the total number of trials by the number of possible outcomes. When we toss a coin, for example, the overall possible outcomes are two: heads or tails. However, suppose the coin is flipped 100 times and 30 times it lands on tails. The theoretical chance is then 30/100.


Probability in Theory


Theoretical probability is a method that is based on the possibility of something happening. Let’s say we have dice and want to know the theoretical likelihood that when we roll it, it will land on the number “3.”


Because a dice carries six numbers, there are always six choices. If we wish the dice to land on the number three, we have a 1:6 chance of doing so.


Personal Probability


Personal probability is another name for subject probability. Because it is based on the logic and conclusions of the individual. In other words, it is the likelihood that a person’s expected event will occur. Subjective probability has no formal procedures or calculations.


Because it is founded on the knowledge of an individual. Consider the following scenario: you are watching a football match. And the host team will win the game during the match. Your decisions may be based on facts or opinions on the game between the two teams, as well as the team’s chances of winning.

Statistical types


Statistics are divided into two categories.




The statistician describes the purpose in descriptive statistics. We utilize numerical metrics to describe the characteristics of a set of data. Apart from that, the descriptive statistic is all about data presentation and gathering.


It is not as straightforward as statisticians believe. Statisticians must understand how to construct tests and select the appropriate focus group. They should also eliminate biases in order to obtain more reliable outcomes from experiments. Descriptive statistics are divided into two categories.

Statistical Inference


Inferential statistics is a difficult subject. It is more difficult to understand than descriptive statistics. Complex mathematical calculations are used to create it. For scientists, these computations are extremely useful.


Allowing them to extrapolate trends about a wider group from a study of a subset of that population. Inferential statistics are used to make the majority of future forecasts. To derive the appropriate conclusions from his research, statisticians must create the appropriate experiment.

Model of Probability


This model is used to incorporate random variables and probability distributions into an event or phenomenon’s model. We know that in the deterministic paradigm, an event has only one possible consequence.


We have a solution in the form of the probability distribution for the probabilistic model. These models are useful because they alert us to all aspects of a situation that we may otherwise overlook.


Consider the following scenario: you have life insurance. That is based on the fact that you will undoubtedly die. However, you have no idea when you will die.


Model Statistical


A statistical model is a mathematical model of some sort. It involves a set of statistical assumptions about how sample data is generated. It depicts the data and the data generation process in an idealized form.


A mathematical link between one or more non-random variables and random variables is also known as statistical modal. All statistical hypothesis tests and statistical estimators have also been derived using the statistics model.




Probability’s Applications


Every change you make involves some element of probability. In other terms, it is a study of events that may or may not occur. Probability is an important aspect of our lives.


We unconsciously use it several times during the day. Most of the time, we use it without even realizing it. Everything is a possibility, from weather forecasts to our odds of dying in an accident.







Statistical Applications


Statistics keep us informed and aware of what is going on in the world. Because our environment is filled of information, statistics is an important element of our lives. Statistics Help determines all of this information mathematically. It means that statistics are useful in obtaining accurate data. Here are some examples of how statistics are used in our daily lives.








Probability and statistics are important aspects of mathematics. However, as statistics students, you must understand the distinction between these two concepts. There are numerous parallels between these two. However, they are vastly distinct from one another.


You should now be able to distinguish between probability and statistics. So be prepared to respond whenever someone asks what the difference is between probability and statistics.

What is probability, exactly?


It is a field of mathematics that studies the random occurrences that will occur in an event. It is impossible to predict the outcome before the event occurs. However, there are always multiple outcomes.
