# What is the p-value? Step By Step Guide! 17 February 2023

A p-value is commonly used to test statistical data. It is the value of all the observations likely to find in and compared with the null hypothesis that was true. P Value Calculator is used to find all the observation values. The p-value describes the probability value. It also explains how likely your data would be under the null hypothesis.

The whole procedure is done on the basis of probability. The likelihood of happening or the occurrence of data values. The p-value calculator tests the whole statistical data of the observation and the probability of the chances. How many times the same data or value is going to repeat during your test experiment? The p-value would also describe the level of extreme when the null hypothesis would be true. Then the p-value would be smaller otherwise the test values go away from the null hypothesis test values. The p-value is a simple way to test the hypothetical result with the real-time result.

P value calc can be a source of providing the most important information regarding a market and the product and the services that are best to launch on this particular market. Brands can change their path and strategic path without putting a huge amount of money into research.
The p-value and its importance:

When conducting research on a large population. Then it's impossible for you to conduct research on such a huge sample. In this condition, you need to calculate the p-value of the population. It would assist to find the data about that whole population and conclusion.
The statistical data can’t describe the absolute value of the data. But statistical data provides you with a value close to this. The error is so small that you can ignore it.  Most of the time it considers the true data from a large population.

This type of statistical research is normally conducted when companies want to know market trends. What kind of product and service is the best for a particular market? This kind of data is the backbone for implementing the company’s strategies in a particular marketplace. The p-score calculator assists you in testing the hypothesis on the whole population.
Brands can change their path and strategic path without putting a huge amount of money into research.

How can we calculate the P-Value?
The P-value is quite useful and it is a statistical term to determine the hypothesis. P-values are used to test if the null hypothesis is true. It also assists to test the probability of the sampling. Students may wonder, how to calculate p value?
You can say it is simply the representation of the odds of happening. When a particular event happens if our null hypothesis is true! To find the p-value, you require to draw a null hypothesis. It is better to understand the null hypothesis first:
What is a null hypothesis:
The null hypothesis is a hypothesis in which you are claiming that a certain population or a market is coming just by chance or the result is coming just by chance. The result you are calming and the actual result happening is just by chance. You can say that the null hypothesis is used to test our p-value Calculator values.

What is the alternative hypothesis?
An alternative hypothesis test is also used to refine your p-value. In this test, you are using the matching result you are getting in the real world. Not by chance, but by some kind of outside element producing. Then compare the same results as our p-value calculator is producing the result about a certain type of population.

How to calculate the p-value?
The P-Value Calculator reflects whether you can reject or accept the null hypothesis or not. For this, you need to estimate the mean value or the alpha value of the sample. You are going to test by testing for the p-value. Here two situations arise from the test of the sample:

Consider the p-value is less than the alpha or the mean value. Then you can reject the null hypothesis totally. You come to the conclusion the alternative hypothesis is true for the values.
If the p-value calculator predicts a value, which is greater or equal to the alpha. In this case situation, you can’t reject the null hypothesis. you can’t avoid the null hypothesis in this situation.
It doesn’t mean that the null hypothesis is true. But you can’t certainly reject it totally.

The P Value Calculator is reflecting values on the basis of the probability factor.  When you are tossing a coin in the air, it has a probability of coming as the tale is ½. If it is coming only as head more than 3 times you can say, it is by chance.
