Statistical significance is achieved when the result is very unlikely to occur by chance. Practical significance is related to whether common sense suggests that the treatment makes enough of a difference to justify its use.

What is the difference between statistical significance and practical significance?
How do you know if something is statistically different?
What's the difference between parameter and statistic?
What does it mean for the findings of a statistical analysis of data to be statistically significant quizlet?
What is the difference between statistical significance and the strength of the relationship?
What does statistical significance indicate?
Why does statistical significance not imply importance?
How do you know if the difference between groups is statistically significant?
How do you find the difference between means?
How do you tell if the difference between two numbers is statistically significant?
What does it mean to be statistically significant?
1. For a result to be statistically significant means that the probability of the results observed been due to chance is very low or impossible. For a result to be statiscally significant means that the differences observed between the experimental group and the control group of the experiment is not due to chance or sampling errors.
What is practical significance?
Practical significance refers to how practical it is to convert a result observed in the laboratory to use in real world scenario. The difference observed between two variables in an experimental set up may be so small that it may not be worth it to produce it on a large scale for human use. Thus, the difference between statistical ...
What is a test statistic?
The test statistic tells you how different two or more groups are from the overall population mean, or how different a linear slope is from the slope predicted by a null hypothesis. Different test statistics are used in different statistical tests.
What is statistical test?
They can be used to: determine whether a predictor variable has a statistically significant relationship with an outcome variable. estimate the difference between two or more groups. Statistical tests assume a null hypothesis of no relationship or no difference between groups.
What is independent observation?
Independence of observations (a.k.a. no autocorrelation): The observations/variables you include in your test are not related (for example, multiple measurements of a single test subject are not independent, while measurements of multiple different test subjects are independent).
What is a parametric test?
Choosing a parametric test: regression, comparison, or correlation. Parametric tests usually have stricter requirements than nonparametric tests, and are able to make stronger inferences from the data. They can only be conducted with data that adheres to the common assumptions of statistical tests.
What are the most common types of parametric tests?
The most common types of parametric test include regression tests, comparison tests, and correlation tests .
What is a comparison test?
Comparison tests. Comparison tests look for differences among group means. They can be used to test the effect of a categorical variable on the mean value of some other characteristic. T-tests are used when comparing the means of precisely two groups (e.g. the average heights of men and women).
When to use a T-test?
T-tests are used when comparing the means of precisely two groups (e.g. the average heights of men and women).

in this question. We're trying to understand what is statistical significance and what is practical significance. The statistical significance is indicated when methods of statistics are used to reach a conclusion that a treatment is effective, for example.
