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
Directional Hypothesis Examples. 1. Exercise and Heart Health. Research suggests that as regular physical exercise (independent variable) increases, the risk of heart disease (dependent variable) decreases (Jakicic, Davis, Rogers, King, Marcus, Helsel, Rickman, Wahed, Belle, 2016). In this example, a directional hypothesis anticipates that the ...
Directional and non-directional hypothesis: A Comprehensive Guide
Definition of directional hypothesis. 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 ...
Research Hypothesis In Psychology: Types, & Examples
Examples. A research hypothesis, in its plural form "hypotheses," is a specific, testable prediction about the anticipated results of a study, established at its outset. It is a key component of the scientific method. Hypotheses connect theory to data and guide the research process towards expanding scientific understanding.

Understanding Statistical Testing
By the term hypothesis, I mean a formal proposition about which its truth or falsity is unknown. ... Directional hypotheses are sometimes introduced as a point hypothesis and a directional hypothesis such as H 0: θ = 0 versus H 1: θ > 0 (Neutens & Rubinson, ... This is the basis for hypothesis-driven science. For example, ...
The What, Why and How of Directional Hypotheses
A directional hypothesis, often referred to as a one-tailed hypothesis, is an essential part of research that predicts the expected outcomes and their directions. ... by definition, a hypothesis - a proposed explanation or prediction that is subject to testing and verification. So, don't be disheartened if your directional hypothesis doesn ...
Directional Hypothesis
Definition: A directional hypothesis is a specific type of hypothesis statement in which the researcher predicts the direction or effect of the relationship between two variables. Key Features. 1. Predicts direction: Unlike a non-directional hypothesis, which simply states that there is a relationship between two variables, a directional ...
7.3: The Research Hypothesis and the Null Hypothesis
The Research Hypothesis. A research hypothesis is a mathematical way of stating a research question. A research hypothesis names the groups (we'll start with a sample and a population), what was measured, and which we think will have a higher mean. The last one gives the research hypothesis a direction. In other words, a research hypothesis ...

Data analysis: hypothesis testing: 4.3 One-sided tests
4.3 One-sided tests. As well as non-directional hypotheses, you will also encounter hypotheses that have a less than or equal to (≤) and greater than (>) supposition (sign) in the statement (as you saw in Activity 3). This is called a directional hypothesis. A directional hypothesis is a type of research hypothesis that aims to predict the ...
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.
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 ...
Aims And Hypotheses, Directional And Non-Directional
If the findings do support the hypothesis then the hypothesis can be retained (i.e., accepted), but if not, then it must be rejected. 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 ...
Causal vs. Directional Hypothesis
Whereas a relational hypothesis can be non-directional, causal hypotheses are always directional. This means that a causal hypothesis must either propose a negative or positive cause-and-effect ...
Types of Research Hypotheses
There are seven different types of research hypotheses. Simple Hypothesis. A simple hypothesis predicts the relationship between a single dependent variable and a single independent variable. Complex Hypothesis. A complex hypothesis predicts the relationship between two or more independent and dependent variables. Directional Hypothesis.
What is a Hypothesis
Definition: Hypothesis is an educated guess or proposed explanation for a phenomenon, based on some initial observations or data. It is a tentative statement that can be tested and potentially proven or disproven through further investigation and experimentation. Hypothesis is often used in scientific research to guide the design of experiments ...
Hypothesis: Definition, Examples, and Types
A hypothesis is a tentative statement about the relationship between two or more variables. It is a specific, testable prediction about what you expect to happen in a study. It is a preliminary answer to your question that helps guide the research process. Consider a study designed to examine the relationship between sleep deprivation and test ...
7.2.2 Hypothesis
The Experimental Hypothesis: Directional A directional experimental hypothesis (also known as one-tailed) predicts the direction of the change/difference (it anticipates more specifically what might happen); A directional hypothesis is usually used when there is previous research which support a particular theory or outcome i.e. what a researcher might expect to happen
The Research Hypothesis: Role and Construction
A hypothesis (from the Greek, foundation) is a logical construct, interposed between a problem and its solution, which represents a proposed answer to a research question. It gives direction to the investigator's thinking about the problem and, therefore, facilitates a solution. Unlike facts and assumptions (presumed true and, therefore, not ...
Directional Hypothesis
A Level Psychology Topic Quiz - Research Methods. Quizzes & Activities. A directional hypothesis is a one-tailed hypothesis that states the direction of the difference or relationship (e.g. boys are more helpful than girls).
Directional Hypothesis definition
Directional Hypothesis. In statistics and science, a directional hypothesis predicts that a specific relationship between numbers or objects will exist, and furthermore, the direction in which that relationship is heading. In math, this relates to the concept of the null hypothesis where a two-tailed solution might exist, but that only one of ...
Hypothesis
The hypothesis of Andreas Cellarius, showing the planetary motions in eccentric and epicyclical orbits.. A hypothesis (pl.: hypotheses) is a proposed explanation for a phenomenon.For a hypothesis to be a scientific hypothesis, the scientific method requires that one can test it. Scientists generally base scientific hypotheses on previous observations that cannot satisfactorily be explained ...
9.1: Hypothesis Tests for Regression Coefficients
Note that this is a directional hypothesis since we are posting a negative relationship. Typically, a directional hypothesis implies a one-tailed test where the critical value is 0.05 on one side of the distribution. A non-directional hypothesis, β≠0β≠0 does not imply a particular direction, it only implies that there is a relationship ...
Consistent time allocation fraction to vegetation green-up ...
An alternative hypothesis, which we termed the constant time allocation hypothesis, suggests a relatively stable time allocation due to a carryover effect among the timing and duration of other phenological events , implying that this allocation is intrinsically biologically regulated. For example, an earlier SOS could lead to an earlier POS.
