In statistical hypothesis testing, the alternative hypothesis is one of the proposed propositions in the hypothesis test. In general the goal of hypothesis test is to demonstrate that in the given condition, there is sufficient evidence supporting the credibility of alternative hypothesis instead of the exclusive proposition in the test (null hypothesis).

Heuer outlines the ACH process in considerable depth in his book, Psychology of Intelligence Analysis. [1] It consists of the following steps: Hypothesis – The first step of the process is to identify all potential hypotheses, preferably using a group of analysts with different perspectives to brainstorm the possibilities.
The alternative hypothesis, as the name suggests, is the alternative to the null hypothesis: it states that there is some kind of relation. The alternative hypothesis may take several forms, depending on the nature of the hypothesized relation; in particular, it can be two-sided (for example: there is some effect, in a yet unknown direction) or ...
We define two hypotheses the null hypothesis, and the alternative hypothesis. If we design the test such that α is the significance level - being the probability of rejecting H 0 {\displaystyle H_{0}} when H 0 {\displaystyle H_{0}} is in fact true, then the power of the test is 1 - β where β is the probability of failing to reject H 0 ...
alternative =indicates the alternative hypothesis and must be one of "two.sided", "greater" or "less" conf.level = confidence level for the returned confidence interval. Examples of the sign test using the R function binom.test The sign test example from Zar [5] compared the length of hind legs and forelegs of deer. The hind leg was longer than ...
Another factor that determines how much we use counterfactual thought is how close we were to an alternative outcome. This is especially true when there is a negative outcome that was this close to a positive outcome. For example, in a study by Meyers-Levy and Maheswaran, subjects were more likely to counterfactual think alternative ...
But in psychology, there are many alternative hypotheses for every null hypothesis. [164] [165] In particular, when statistical studies on extrasensory perception reject the null hypothesis at extremely low p-value (as in the case of Daryl Bem), it does not imply the alternative hypothesis "ESP exists". Far more likely is that there was a small ...
According to Batson's empathy-altruism hypothesis, if someone feels empathy towards another person, they will help them, regardless of what they can gain from it. [2] An alternative hypothesis is empathy-joy, which states a person helps because they find pleasure at seeing another person experience relief. [3]
