Can Theory Be Proven? Can theory be proven? A theory isn’t speculation about what might be true. It is a set of propositions that seek to explain a particular phenomenon or set of facts. A theory can be tested and shown to be accurate or modified as the evidence requires. Even when a theory is
Can The Hypothesis Be A Question? Can the hypothesis be a question? Your hypothesis is not the scientific question in your project. The hypothesis is an educated, testable prediction about what will happen. Is a hypothesis the same as a question? Both are aspects of the Scientific Method, but they are not identical. A research
Can You Compare P-values? Can you compare P-values? In your particular case there is absolutely no doubt that you can directly compare the p-values. If the sample size is fixed (n=1000), then p-values are monotonically related to t-values, which are in turn monotonically related to the effect size as measured by Cohen’s d. How do
How Is Hypothesis Testing Used In Public Health? Hypothesis testing is the process used to evaluate the strength of evidence from the sample and provides a framework for making determinations related to the population, ie, it provides a method for understanding how reliably one can extrapolate observed findings in a sample under study to the
Did Atiyah Prove The Riemann Hypothesis? Did Atiyah prove the Riemann hypothesis? The most recent famous claim came in September, 2018 from British-Lebenese mathematician Sir Micheal Atiyah. He used Todd functions and mentioned the Fine Structure constant a fundamental physical constant in his proof by contra- diction [17]. Has anyone proved the Riemann hypothesis? Reimann
What Does It Mean If Your Hypothesis Is Supported? What does it mean if your hypothesis is supported? If the results fully support your hypothesis and your reasoning in the Introduction were basically sound, then elaborate on your reasoning by showing how the science behind the experiment provides an explanation for the results. What does
Do You Ever Reject The Alternative Hypothesis? Do you ever reject the alternative hypothesis? After you perform a hypothesis test, there are only two possible outcomes. When your p-value is less than or equal to your significance level, you reject the null hypothesis. The data favors the alternative hypothesis. Which hypothesis means rejection of alternative
What Is An Example Of A Non Directional Hypothesis? For example, a researcher might hypothesize that college students will perform differently from elementary school students on a memory task without predicting which group of students will perform better. Also called nondirectional alternative hypothesis; two-tailed (alternative) hypothesis. What is a non-directional hypothesis? A nondirectional hypothesis is
Does A Hypothesis Need To Be An IF-THEN Statement? Does a hypothesis need to be an IF-THEN statement? They are necessary in a formalized hypothesis. But not all if-then statements are hypotheses. For example, “If I play the lottery, then I will get rich.” This is a simple prediction. In a formalized hypothesis, a tentative
Does A Hypothesis Need To Be Falsifiable? Does a hypothesis need to be falsifiable? A hypothesis must also be falsifiable. That is, there must be a possible negative answer. For example, if I hypothesize that all green apples are sour, tasting one that is sweet will falsify the hypothesis. Note, however, that it is never
