Was Statistically Significant Better?

In principle, a statistically significant result (usually a difference) is a result that's not attributed to chance. More technically, it means that if the Null Hypothesis is true (which means there really is no difference), there's a low probability of getting a result that large or larger.

Is being statistically significant good?

“Statistical significance helps quantify whether a result is likely due to chance or to some factor of interest,” says Redman. When a finding is significant, it simply means you can feel confident that's it real, not that you just got lucky (or unlucky) in choosing the sample.

Is there a statistically significant difference?

If the absolute value of the test statistic is greater than 1.96* standard deviations of the mean, then it's considered a statistically significant difference.
