The alternative hypothesis and null hypothesis are types of conjectures used in statistical tests, which are formal methods of reaching conclusions or making judgments on the basis of data. In statistical hypothesis testing, the null hypothesis and alternative hypothesis are two mutually exclusive statements.

Null & Alternative Hypotheses
The alternative hypothesis (H a) is the other answer to your research question. It claims that there's an effect in the population. Often, your alternative hypothesis is the same as your research hypothesis. In other words, it's the claim that you expect or hope will be true. The alternative hypothesis is the complement to the null hypothesis.
What is an Alternative Hypothesis in Statistics?
Null hypothesis: µ ≥ 70 inches. Alternative hypothesis: µ < 70 inches. A two-tailed hypothesis involves making an "equal to" or "not equal to" statement. For example, suppose we assume the mean height of a male in the U.S. is equal to 70 inches. The null and alternative hypotheses in this case would be: Null hypothesis: µ = 70 inches.
9.1: Null and Alternative Hypotheses
The actual test begins by considering two hypotheses.They are called the null hypothesis and the alternative hypothesis.These hypotheses contain opposing viewpoints. \(H_0\): The null hypothesis: It is a statement of no difference between the variables—they are not related. This can often be considered the status quo and as a result if you cannot accept the null it requires some action.
Alternative hypothesis
The alternative hypothesis is used to decide whether a test should be one-tailed or two-tailed. The critical region. The null hypothesis is rejected if the test statistic falls within a critical region that has been chosen by the statistician. The critical region is a set of values that may comprise: ...
9.1 Null and Alternative Hypotheses
The actual test begins by considering two hypotheses.They are called the null hypothesis and the alternative hypothesis.These hypotheses contain opposing viewpoints. H 0, the —null hypothesis: a statement of no difference between sample means or proportions or no difference between a sample mean or proportion and a population mean or proportion. In other words, the difference equals 0.
10.2: Null and Alternative Hypotheses
The null hypothesis ( H0. H 0. ) is a statement about the population that either is believed to be true or is used to put forth an argument unless it can be shown to be incorrect beyond a reasonable doubt. The alternative hypothesis ( Ha. H a. ) is a claim about the population that is contradictory to H0. H 0.
Alternative hypothesis
The alternative hypothesis is one of two mutually exclusive hypotheses in a hypothesis test. The alternative hypothesis states that a population parameter does not equal a specified value. Typically, this value is the null hypothesis value associated with no effect, such as zero.If your sample contains sufficient evidence, you can reject the null hypothesis and favor the alternative hypothesis.
8.4: The Alternative Hypothesis
The alternative hypothesis is simply the reverse of the null hypothesis, and there are three options, depending on where we expect the difference to lie. 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 ...
Null Hypothesis and Alternative Hypothesis
The Alternative Hypothesis . The alternative or experimental hypothesis reflects that there will be an observed effect for our experiment. In a mathematical formulation of the alternative hypothesis, there will typically be an inequality, or not equal to symbol. This hypothesis is denoted by either H a or by H 1.
9.1: Null and Alternative Hypotheses
Hypothesis. a statement about the value of a population parameter, in case of two hypotheses, the statement assumed to be true is called the null hypothesis (notation \ (H_ {0}\)) and the contradictory statement is called the alternative hypothesis (notation \ (H_ {a}\)).
9.1 Null and Alternative Hypotheses
The alternative hypothesis is the contender and must win with significant evidence to overthrow the status quo. This concept is sometimes referred to the tyranny of the status quo because as we will see later, to overthrow the null hypothesis takes usually 90 or greater confidence that this is the proper decision.

Null vs. Alternative Hypothesis [Overview]
The alternative hypothesis (H a H_a H a or H 1 H_1 H 1 ) is the hypothesis that stands contrary to the null hypothesis. The alternative hypothesis represents the research hypothesis—what you as the statistician are trying to prove with your data. In medical studies, where scientists are trying to demonstrate whether a treatment has a ...
What are null and alternative hypotheses?
Null and alternative hypotheses are used in statistical hypothesis testing. The null hypothesis of a test always predicts no effect or no relationship between variables, while the alternative hypothesis states your research prediction of an effect or relationship.
Alternative Hypothesis
The alternative hypothesis will then be formulated as follows: H 1:: the values of \ ( { \theta_i (i=1,\ldots,k) } \) are not all identical. This means that only one parameter needs to have a different value to those of the other parameters in order to reject the null hypothesis and accept the alternative hypothesis.

Alternate Hypothesis in Statistics: What is it?
With the null hypothesis, you get what you expect, from a historical point of view. In hypothesis-testing, there are always two competing hypotheses under consideration [1]: The status quo (null) hypothesis (H 0), The research (alternate) hypothesis (H a or H 1). You can think of the alternate hypothesis as just an alternative to the null. For ...
Alternative Hypothesis: Definition, Types and Examples
An alternative theory is the one tested by the researcher and if the researcher gathers enough data to support it, then the alternative hypothesis replaces the null hypothesis. Null and alternative hypotheses are exhaustive, meaning that together they cover every possible outcome.
