What is a Directional Hypothesis? (Definition & Examples)
A hypothesis test can either contain a directional hypothesis or a non-directional hypothesis: Directional hypothesis: The alternative hypothesis contains the less than ("<") or greater than (">") sign. This indicates that we're testing whether or not there is a positive or negative effect. Non-directional hypothesis: The alternative ...
Directional Hypothesis: Definition and 10 Examples
Non-directional hypothesis: A non-directional hypothesis denotes the possibility of a relationship between two variables (the independent and dependent variables), although this hypothesis does not venture a prediction as to the direction of this relationship (Ali & Bhaskar, 2016). For example, a non-directional hypothesis might state that ...
Research Hypothesis In Psychology: Types, & Examples
A non-directional hypothesis, also known as a two-tailed hypothesis, predicts that there is a difference or relationship between two variables but does not specify the direction of this relationship. It merely indicates that a change or effect will occur without predicting which group will have higher or lower values.
Directional and non-directional hypothesis: A Comprehensive Guide
Directional hypotheses, also known as one-tailed hypotheses, are statements in research that make specific predictions about the direction of a relationship or difference between variables. Unlike non-directional hypotheses, which simply state that there is a relationship or difference without specifying its direction, directional hypotheses ...
Hypotheses; directional and non-directional
The directional hypothesis can also state a negative correlation, e.g. the higher the number of face-book friends, the lower the life satisfaction score ". Non-directional hypothesis: A non-directional (or two tailed hypothesis) simply states that there will be a difference between the two groups/conditions but does not say which will be ...
Directional vs. Non-Directional Hypothesis in Research
A non-directional hypothesis, also known as a two-tailed hypothesis, does not make a specific prediction about the direction of the relationship between variables. Instead, it states that there is a relationship, but without indicating whether it will be positive or negative.
5.2
5.2 - Writing Hypotheses. The first step in conducting a hypothesis test is to write the hypothesis statements that are going to be tested. For each test you will have a null hypothesis ( H 0) and an alternative hypothesis ( H a ). When writing hypotheses there are three things that we need to know: (1) the parameter that we are testing (2) the ...
Types of Research Hypotheses
Non-directional Hypothesis A non-directional hypothesis does not predict the exact direction or nature of the relationship between the two variables. A researcher would utilize this kind of hypothesis if it is not based on theory or when the new research findings contradict the previous research.
Aims And Hypotheses, Directional And Non-Directional
Three Different Hypotheses: (1) Directional Hypothesis: states that the IV will have an effect on the DV and what that effect will be (the direction of results). For example, eating smarties will significantly improve an individual's dancing ability. When writing a directional hypothesis, it is important that you state exactly how the IV will ...
PDF Chapter 6: Research methods Hypotheses: directional or non-directional
If a hypothesis does not state a direction but simply says that one factor affects another, or that there is an association or correlation between two variables then it is called a non-directional (two-tailed) hypothesis. Distinguishing between directional and non-directional hypotheses is really very straightforward but be careful!
Directional vs Non-Directional Hypothesis
Non-directional hypotheses, also known as null hypotheses, are formulated when researchers do not have a specific expectation about the direction of the relationship between variables. Instead, non-directional hypotheses state that there is no significant relationship, difference, or effect between variables. These hypotheses are objective and ...
Directional Test (Directional Hypothesis)
Hypothesis Testing >. A directional test is a hypothesis test where a direction is specified (e.g. above or below a certain threshold). For example you might be interested in whether a hypothesized mean is greater than a certain number (you're testing in the positive direction on the number line), or you might want to know if the mean is less ...
7.5.1: Critical Values
In statistical language, this is an example of a non-directional hypothesis, also known as a two-sided test. It's called this because the alternative hypothesis covers the area on both "sides" of the null hypothesis, and as a consequence the critical region of the test covers both tails of the sampling distribution (2.5% on either side if ...
One-Tailed and Two-Tailed Hypothesis Tests Explained
One-tailed hypothesis tests are also known as directional and one-sided tests because you can test for effects in only one direction. When you perform a one-tailed test, the entire significance level percentage goes into the extreme end of one tail of the distribution. In the examples below, I use an alpha of 5%.
8.4: The Alternative Hypothesis
Thus, our alternative hypothesis is the mathematical way of stating our research question. If we expect our obtained sample mean to be above or below the null hypothesis value, which we call a directional hypothesis, then our alternative hypothesis takes the form: HA: μ > 7.47 or HA: μ < 7.47 H A: μ > 7.47 or H A: μ < 7.47.
7.3: The Research Hypothesis and the Null Hypothesis
Non-Directional Research Hypothesis. A non-directional hypothesis states that the means will be different, but does not specify which will be higher. In reality, there is rarely a situation in which we actually don't want one group to be higher than the other, so we will focus on directional research hypotheses.

Non-Directional Hypothesis
Non-Directional Hypothesis. A non-directional hypothesis is a two-tailed hypothesis that does not predict the direction of the difference or relationship (e.g. girls and boys are different in terms of helpfulness).
Non-Directional Hypothesis:
A non-directional hypothesis, also known as a two-tailed hypothesis, is a type of hypothesis that does not specify the direction of the relationship between variables or the difference between groups. Instead of predicting a specific direction, a non-directional hypothesis suggests that there will be a significant relationship or difference ...
Directional & Non-Directional Hypothesis
Non-directional Hypothesis: It involves an open-ended non-directional hypothesis that predicts that the independent variable will influence the dependent variable; however, the nature or direction of a relationship between two subject variables is not defined or clear. For Example, there will be a difference in the performance of girls & boys ...
Non Directional Hypothesis
A non-directional hypothesis, also known as a two tailed hypothesis, is a type of hypothesis that predicts a relationship between variables without specifying the direction of that relationship. Unlike directional hypotheses that predict a specific outcome, non-directional hypotheses simply suggest that a relationship exists without indicating ...
