Statistically significant is the term used to define when two data are distinct enough in value as to be considered different values. To determine whether two data are close enough in value or distinct enough in value to be considered the same or different, usually you have to do a p-test or a t-test, depending on the type of data that you are looking at. Then confer with the corresponding chart for the test that you did to see whether or not the data is statistically significant.

What is a statistically significant?
if it is unlikely to have happened by chance
What does it mean for the findings of a statistical analysis of data to be statistically significant?
Data is statistically significant if the p (probability) value is below a certain level (ex: 5% or 1%). The p value describes how often one would receive the results they got if left to chance alone. The lower the p value, the less likely it is that your results were due to chance and is stronger evidence against the null hypothesis. Also important to keep in mind is that just because something is statistically significant does not mean it is practically significant.
Can paired means be statistically significant?
No. However, the difference between them can be.
Is it possible for the results of the study to be of practical importance even though they are not statistically significant?
Yes!
Is statistical significance below or above 0.05?
If the outcome is below or equal to 0.05, then it is statistically significant; above is not.
