Detailed explanation-1: -In scientific studies, this is known as the “p-value.” If it is unlikely enough that the difference in outcomes occurred by chance alone, the difference is pronounced “statistically significant."
Detailed explanation-2: -This result is a ‘statistically significant’ result. A set of measurements or observations in a statistical study is said to be statistically significant if it is unlikely to have occurred by chance.
Detailed explanation-3: -A data set provides statistical significance when the p-value is sufficiently small. When the p-value is large, then the results in the data are explainable by chance alone, and the data are deemed consistent with (while not proving) the null hypothesis.
Detailed explanation-4: -statistical-significance is the degree to which an event is unlikely to have occurred by chance alone. In other words, it tells how likely the event occurred due to some manipulation or actual difference between the groups in the study.
