How do you explain p-value to non technical person?

How do you explain p-value to non technical person?

The p-value signifies the strength of the evidence against the null hypothesis. The smaller the p-value, the more powerful the evidence is to suggest that the null hypothesis should be rejected, and that the alternative hypothesis should be selected (usually the threshold, or significance level is p <= 0.05).

Can you explain statistical significance to a non technical person?

“Statistically significant” means that something could have just happened randomly, but it is unlikely. Instead, there is much more likely that there is some kind of cause.

What does it mean if there is a significant difference?

A Significant Difference between two groups or two points in time means that there is a measurable difference between the groups and that, statistically, the probability of obtaining that difference by chance is very small (usually less than 5\%).

How do you determine statistical significance?

The level at which one can accept whether an event is statistically significant is known as the significance level. Researchers use a test statistic known as the p-value to determine statistical significance: if the p-value falls below the significance level, then the result is statistically significant.

What is the easiest way to find the p-value?

If your test statistic is positive, first find the probability that Z is greater than your test statistic (look up your test statistic on the Z-table, find its corresponding probability, and subtract it from one). Then double this result to get the p-value.

How do you solve a significant difference?

Subtract the group two mean from the group one mean. Divide each variance by the number of observations minus 1. For example, if one group had a variance of 2186753 and 425 observations, you would divide 2186753 by 424. Take the square root of each result.

What is p-value in simple words?

In statistics, the p-value is the probability of obtaining results at least as extreme as the observed results of a statistical hypothesis test, assuming that the null hypothesis is correct. A smaller p-value means that there is stronger evidence in favor of the alternative hypothesis.
