Paired Samples T Test Null Hypothesis. There are two possible hypotheses in a paired t test. The null hypothesis h0 implies that there is no significant difference between the averages means of the two sets of sample.
Hypotheses of a paired t test there are feasibly 2 hypotheses in a paired t test. Null hypothesis for paired sample t test 1. Null hypothesis for a paired sample t test conceptual explanation 2.
µ 1 µ 2 that is the two samples have both been drawn from the same population.
To determine the value needed to reject the null hypothesis we need to refer to a table see below. The alternative hypothesis is that the two means differ. If the probability value of the null hypothesis is very low less than 0 05 you can conclude that the means are significantly different from each other. A paired samples t test always uses the following null hypothesis.
