Spss 0 05. If a null hypothesis is rejected it means there is an impact. An α of 0 05 indicates that you are willing to accept a 5 chance that you are wrong when you reject the null hypothesis.
However if a null hypothesis is not rejected it means there is no impact. Spss calculates the t statistic and its p value under the assumption that the sample comes from an approximately normal distribution. If a null hypothesis is rejected it means there is an impact.
Sig or p is the probability of finding the observed or a larger deviation from normality in our sample if the distribution is exactly normal in our population.
Spss calculates the t statistic and its p value under the assumption that the sample comes from an approximately normal distribution. If trial 1 is normally distributed in the population there s a mere 0 01 or 1 chance of finding these sample data. However if a null hypothesis is not rejected it means there is no impact. Is 0 05 then the null hypothesis is not rejected.
