Which of the following is an example of an alternative hypothesis?
The alternate hypothesis is just an alternative to the null. For example, if your null is “I’m going to win up to $1000” then your alternate is “I’m going to win more than $1000.” Basically, you’re looking at whether there’s enough change (with the alternate hypothesis) to be able to reject the null hypothesis.
What is alternative hypothesis in research?
An alternative hypothesis is one in which a difference (or an effect) between two or more variables is anticipated by the researchers; that is, the observed pattern of the data is not due to a chance occurrence. The concept of the alternative hypothesis is a central part of formal hypothesis testing.
What is an example of a null hypothesis and alternative hypothesis?
The null hypothesis is the one to be tested and the alternative is everything else. In our example: The null hypothesis would be: The mean data scientist salary is 113,000 dollars. While the alternative: The mean data scientist salary is not 113,000 dollars.
How do you write a simple hypothesis?

What do you need to test a hypothesis?
Statistical analysts test a hypothesis by measuring and examining a random sample of the population being analyzed. All analysts use a random population sample to test two different hypotheses: the null hypothesis and the alternative hypothesis.
What is hypothesis formulation?
A hypothesis is used to explain a phenomenon or predict a relationship in communication research. Formulating a hypothesis requires a specific, testable, and predictable statement driven by theoretical guidance and/or prior evidence. A hypothesis can be formulated in various research designs.
What are the characteristics of a good research hypothesis?
Following are the characteristics of hypothesis:
- The hypothesis should be clear and precise to consider it to be reliable.
- If the hypothesis is a relational hypothesis, then it should be stating the relationship between variables.
- The hypothesis must be specific and should have scope for conducting more tests.
Is a quality of good hypothesis?
The hypothesis has to be formulated in such a form to attain the following qualities: (i) It should be based on known facts and must have roots in the existing theories of knowledge. (ii) The hypothesis should be testable. (This is the most important requirement).
What is a good hypothesis statement?
A good hypothesis will be written as a statement or question that specifies: The dependent variable(s): who or what you expect to be affected. The independent variable(s): who or what you predict will affect the dependent variable. What you predict the effect will be.
