A directional hypothesis is a prediction made by a researcher regarding a positive or negative change, relationship, or difference between two variables of a population. A directional hypothesis is also known as a one-tailed test, and is a prediction made that is based on past knowledge of the subject. Put Quizlet study sets to work when you prepare for tests in Directional Hypothesis and other concepts today. West Yorkshire, there will be a positive correlation between the number of stressful life events experienced in the last year and the number of coughs and colds suffered, whereby the more life events you have suffered the more coughs and cold you will have had”. Short exam-style and exam-standard assessment papers (with mark schemes) to help test specific units or key topics in the relevant specification. Null Hypotheses, Research Hypotheses, and Theories, • Null hypothesis rejected → research hypothesis supported, concerns the relationship between one independent and one dependent variable, concerns a relationship where two or more independent variables, or two or more dependent variables, or both, are being examined, concerns the action of two variables in conjunction with each other, (Ho) predicts that no relationship exists between variables, and it is subjected to statistical analysis, or alternative hypothesis (H1); states the expected relationship between variables, the researcher merely predicts that a relationship exists; the direction of the relationship is not presented, the researcher predicts the type of relationship that is expected; they have several advantages- they make the expectations clear, allow more precise testing of theoretical propositions, and allow the use of one-tailed statistical tests. If we had a correlational study, the directional hypothesis would state whether we expect a positive or a negative correlation, we are stating how the two variables will be related to each other, e.g. There will NOT be a positive correlation between the number of stress life events experienced in the last year and the number of coughs and colds suffered, whereby the more life events you have suffered the more coughs and cold you will have had”, With a non-directional or  two tailed hypothesis…. Given the data, what are the odds of being unfaithful if unhappy? Learn vocabulary, terms, and more with flashcards, games, and other study tools. there will be a significant correlation between variable A and variable B. Null hypothesis The null hypothesis states that the alternative or experimental hypothesis is NOT the case, if your experimental hypothesis was directional you would say….

(2) (b) Outline one strength and one weakness of the random sampling method. we are not able to manipulate the IV as in a natural or quasi-experiment , or if some other research method has been used, then we call it an “alternate hypothesis”, alternate to the null.
