[* black] Determine whether to reject the null hypothesis by looking at the sig value. If the sig value is less than the alpha value, the null hypothesis is rejected. Another way to determine whether to reject the null hypothesis is by looking at the confidence intervals. If 0 is not within these intervals you can reject the null hypothesis.
[* black] '''P-value / sig.: '''The number that says where on a standard bell curve a value needs to be in order to be statistically significant. [ex.: p-value of .05 means that a value must be outside the middle 95% of a bell curve to be statistically significant] (if we use this, we should probably have an image with it).
[* black] '''Alpha Value''': the probability of rejecting the null hypothesis given that it is true; often equal to the p-value.
[* black] '''Null Hypothesis''': the idea that there is no significant difference between specified populations, any observed difference being due to sampling or experimental error.
[* black] '''Alternative Hypothesis''': the idea that there is a significant difference between specified populations, any observed difference being due to a changed variable.
[* black] '''Confidence Interval Range''': an interval that consist of a range of values that are likely to have the unknown parameter.
