The p value (also sometimes called alpha or probability level) is the percentage chance that the results of a statistical test are due to random error. So a p value of .01, for example, would mean that there is a 1% chance that the results are an error.
p is also the cut-off where a test is considered statistically significant. In Social Sciences, significance is assumed (and therefore the hypothesis supported) when p < .05. Other fields have different cut-offs, and there are times when a researcher may argue for a higher or lower p value.
It is important to note that p is only relevant to statistical significance. It has no bearing on the size or practical importance of results. As a common criticism of statistics is that a p value of .049 is "significant" while .051 is not, most researchers rely as much if not more on measures of effect size and practical application than on statistical significance. However, p remains the accepted convention for hypothesis testing.

Is Inferential statistics based on probability theory?
Yes; the p value used in hypothesis testing is probability. See the related link.
What is the importance of mode in statistics?
It is a value which is observed most often.
What are hypothetical values in statistics mean?
the value that is supposed to exist.
What graph shows data arranged by place value?
statistics
What is distribution is statistics?
The distribution for a variable is the set of value that the variable can take and the probabilities associated with those value.
What is meant by p value?
the p-value is used in statistics. It shows how strong the relationship between the variable are. Normally it is between -1 and 1. The closer it is to one the stronger the relationship is. the p-value is used in statistics. It shows how strong the relationship between the variable are. Normally it is between -1 and 1.

What Interpretation of p value statistics?
p value are used when comparing the likelihood of a stated [null] hypothesis being true against a stated alternative. It is a measure of the probability with which an observation which is at least as extreme as that observed will occur even though the null hypothesis is true.

How do you find the critical value in statistics?
To find the critical value in statistics, it requires a hypothesis testing. Using the critical value approach can also be helpful in this matter.
How do you know when there is a significant difference in statistics?
In statistics, a significant difference is typically determined through hypothesis testing. This involves comparing the observed data with what would be expected by chance alone. If the difference between the observed data and what is expected by chance is large enough, it is considered statistically significant. This is typically determined by calculating a p-value, with a lower p-value indicating a higher level of statistical significance.
What is value of the mode in statistics?
It is the value that occurs most often in a set of data.
