Analysts look to rejectthe null hypothesis because doing so is a strong conclusion. This requires evidence in the form of an observed difference that is too large to be explained solely by chance. Failing to reject the null hypothesis—that the results are explainable by chance alone—is a wea...
In the context of A/B testing, the null hypothesistypically states that there is no difference in the outcomes between the two groups. For example, if you are testing two different landing page variants to determine which leads to more conversions,the null hypothesis could be that there is no...

What is a null hypothesis? Hypothesis: In the field of research, a hypothesis refers to a proposed explanation to a question, and it is often referred to as an ''educated guess''. The hypothesis serves as a starting point for further research. For example, a researcher may hypothesis that...
What is the Alternate Hypothesis? In order to understand what analternate hypothesis(also called analternative hypothesis) is, you first need to understand what thenull hypothesismeans. The wordhypothesismeansa working statement.In statistics, we’re interested in proving whether a working statement (...
In statistics, anull hypothesisis essentially the belief that there's no statistical difference between two data sets being compared. Hypothesis testing involves testing a statistical sample to confirm or reject a null hypothesis. The test is performed by taking a random sample of a population or ...
Null Hypothesis:A null hypothesis is a type of conjecture used in statistics that proposes that no statistical significance exists in a set of given observations, it is denoted as {eq}H_0 {/eq}Answer and Explanation: The null hypothesis, also known as the conjecture, assumes that any kind ...
Instatistics, scientists can perform a number of different significance tests to determine if there is a relationship between two phenomena. One of the first they usually perform is anull hypothesistest. In short, the null hypothesis states that there is no meaningful relationship between two measur...
If you survey everyone in the United States to get their voting preference, that’s a parameter. Parameters contain all of the information. And all the information is rarely known, which is why we need statistics. An important difference between parameters and statistics is that a statistic is...
Based on the banning of null hypothesis significance testing and confidence intervals in Basic and Applied Psychology (2015), this presentation focusses on alternative ways for researchers to think about inference. One section reviews literature on the a priori procedure. The basic idea, here, is ...
