In statistical hypothesis testing you have a null hypothesis against which you are testing an alternative. The hypothesis concerns one or more characteristics of the distribution. It is easier to illustrate the idea of directional and non-directional hypothesis. In studying the academic abilities of boys and girls the null hypothesis would be that boys and girls are equally able. One directional hypothesis would be that boys are more able. The non-directional alternative would be that there is a gender difference. You have no idea whether boys are more able or girls - only that they are not the same.
A non-directional hypothesis only proposes a relationship. In contrast, a directional hypothesis also proposes a direction in the relationship. For example, when one variable increases, the other will decrease.
because Hypothesis itself is an assumption and we always use the term hypothesis only for assuming a perfect answer. so,we use mostly three forms,directional,non-directional and null hypothesis. it is a very simple and straightforward way to prove or make correct our hypothesis.
Boys and girls are different heights. As opposed to: Boys are taller than girls.
When the alternative hypothesis is non-directional, we use a two-tailed test. Example: H0: mean = 50 Ha : mean not equal to 50 Here is a directional hypothesis that would use a one-tailed test. H0: mean = 40 Ha : mean > 40 or H0: mean = 40 Ha: mean < 40
A non-directional hypothesis only proposes a relationship. In contrast, a directional hypothesis also proposes a direction in the relationship. For example, when one variable increases, the other will decrease.
A directional hypothesis predicts the direction of a relationship or difference between variables, stating which variable will have a greater or lesser effect. A non-directional hypothesis simply predicts that a relationship or difference exists between variables without specifying the direction.
directional
Because the statistical test will compare the probability of the outcome under the null hypothesis in relation to the outcome under either a dierectional or non-directional alternative hypothesis.

Distance is nondirectional, such as ten feet, displacement is directional, such as ten feet east of my present position.
A non-directional research hypothesis is a kind of hypothesis that is used in testing statistical significance. It states that there is no difference between variables.
Yes. The hypothesis comes first. That determines the nature of the test.
Whether your alternate hypothesis is directional (one-sided) or non-directional (two-sided) is largely up to you but must be determined before you conduct your experiment, not after. It's not defined by the outcome.

hypothesis mean when you expect what will happen in your experiment to see the differentes. yall didn't know that ,it was so easy!
