Directional research hypothesis: In research methods, a "directional research hypothesis" is described as a prediction that is being made by an experimenter or researcher related to the negative or a positive change, difference, or a relationship between two distinct variables of a specific population. The research prediction in directional research hypothesis is generally based on the extensive experience, past research, literature, accepted theory on the topic.

Jessica is performing directional hypothesis. She is doing a research on entire database and not a sampled way.

Jessica wants to know if the number of students doze off in a lecture and will be calculated by taking the students to the auditorium.

Directional hypothesis research is basically a way to predict a sudden change in a group in a given surrounding and cannot be based on normal research. Rather extensive research is required.

Jessica did an experiment that how students in an auditorium react when the temperature of the room changes. The number of students who doze off is the real answer to be summed up by her.

Jessica followed the principles as are under the definition of directional research.

Hence, Jessica used directional hypothesis to find her theories.
