During the literature review, one of research scholar asked question that if alternate hypothesis and directional hypothesis both are same concept or different. Here is quick input which has given by our professor. (Credit - Dr. Hari Babu)

• Alternate Hypothesis is framed when you state null hypothesis.
• Null Hypothesis (H0) is written as "There is no significant relations/difference between x and y.
• Alternate hypothesis (H1): There is significant relationship/difference between x and y.
• Whenever, null hypothesis is written, the results might accept or reject the null hypothesis.
• If p<0.05, then the researchers reject the null hypothesis, means accept alternate hypothesis.
• Directional Hypothesis states, there is positive/negative relationship between x and y. It means, some direction is mentioned in the hypothesis. However, the direction is specifically to be taken from review of literature.
