Alternative Hypothesis Example: Example:“Plants grow better when given filtered water compared to tap water.” Example:“Professional musicians are more likely to have higher auditory memory than non-musicians.” 2. Null Hypothesis (H0) The null hypothesis is the “no effect” hypothesis. It’...
Hypotheses aren’t about science, experiments, and creating new theories only. While students in science classes formulate a hypothesis every second day, others from non-science fields may find it challenging to write it for an essay or a research paper. This article is here to reveal the natu...
An Example of How to Write a Hypothesis A worker on a fish-farm notices that his trout seem to have more fish lice in the summer, when the water levels are low, and wants to find out why. His research leads him to believe that the amount of oxygen is the reason - fish that are ...
But apart from these variations, we are usually interested in what is called the “alternative hypothesis” and, in contrast to that, the “null hypothesis”. If you think these two should be listed the other way round, then you are right, logically speaking—the alternative should surely ...
To test this hypothesis, we designed and ran an online survey of 1099 parents of school-aged children in Germany in June 2020. In our detailed time-use data, we carefully elicit how many hours students spent with a range of activities per day both before and during the school closures. We...

Artificial intelligence powered by deep neural networks has reached a level of complexity where it can be difficult or impossible to express how a model ma
(Supplementary Fig.8; Friedman test rejected the null hypothesis that distributions are equal withp = 0; post-hoc multiple comparison analysis using Nemenyi’s test showed that the six groups were significantly different withp < 0.001 for all pairs), confirming that the identified link ...
We can also observe that the standard deviation of the international wheat price has the highest value and that the UK’s standard deviations are relatively higher than those of the other countries. The results of a Jarque–Bera test indicate that the null hypothesis of normality is rejected at...
(p = 0.041), which leads us to reject the null hypothesis of this test that humility was normally distributed. Listwise deletion was used to handle missing data, yielding a final sample size of 1152. Results were also consistent if multiple imputation with chained equations was used to ...
