The document discusses directional and non-directional hypotheses. A directional hypothesis specifies the expected direction of the relationship between variables, such as predicting a positive or negative relationship. A non-directional hypothesis simply predicts a difference between variables but does not specify the direction of the difference.

We're testing to see if the mean of the sample group is either less than or greater than the mean of the control group, which - in statistical terms - is considered to be a two-direction or two-tailed test. Remember that the hypotheses were Ho:XbarA = XbarB and Ha: XbarA is not equal to XbarB.

December 13, 2023 - If there is evidence in the literature to support a specific effect of the independent variable on the dependent variable, write a directional (one-tailed) hypothesis. If there are limited or ambiguous findings in the literature regarding the effect of the independent variable on the dependent variable, write a non-directional (two-tailed) hypothesis.

August 6, 2024 - They hypothesized that there would be differences in the outcomes between the two therapies. Involving 150 patients randomly assigned to either manual or exercise therapy over 12 weeks, the study measured outcomes such as pain intensity, range of motion, and patient-reported functional status. The results indicated significant differences between the treatment groups, with varying directions and magnitudes across different measures. This non-directional hypothesis facilitated an unbiased assessment of both therapies’ effectiveness.
