Statistical power is the likelihood that a test (statistical test) will detect an effect when there is an effect there to be detected. Statistical power<span> is inversely related to </span><span>the probability of making a </span>Type II error (Type II errors<span>, or </span>false negatives, occur when you don’t see things that are there) = beta<span>. 
statistical power = 1 – </span>β. The critical value<span> is the </span>value corresponding to a given significance level.  The statistical power<span> is </span>influenced by the choice of significance level for the test (by the critical value). Larger critical value means increased power of the test: <span> the chance of obtaining a statistically significant result is increased (reduces the risk of a </span>Type II error<span> (false negative regarding whether an effect exists) is reduced) . </span>
 
        
                    
             
        
        
        
<span>I am a Carbon atom and I took birth in the air. I had spend a memorable time in a molecule and there were two very nice oxygen atoms too. I just got into the air and I am very excited that I had my complete incoming box of electrons. I am a carbon atom and I have six electrons. Right now I am in a carbon dioxide molecule and I am just wondering in air. While i was enjoying my journey I waved to my friends like oxygen gas which is a molecule of two oxygen atoms.Oxygen atom is my best friend. I’ve heard stories of becoming solids and many different things when i was too young, but now I just like the air and I am loving it.</span>
