30 Questions
What step of the research process requires precision and adherence to the established methodology?
Performing a statistical test
Which statistical test should align with the nature of data and hypotheses being tested?
Regression analysis
What should be evaluated in the context of the null hypothesis after statistical analysis?
Whether to reject the null hypothesis
In hypothesis development, what should the research question be characterized as?
Focused, specific, and researchable
What should researchers consider when discussing their research findings?
Clearly state if the idea was supported or not
After conducting preliminary research, what should the initial answer to the research question be based on?
Existing knowledge about the topic
What is the purpose of constructing a conceptual framework in research?
To identify which variables you will study
What is an essential step in formulating a hypothesis?
Making sure the hypothesis is specific and testable
In academic research, how are hypotheses commonly phrased?
In terms of correlations or effects
What should a hypothesis include for clarity?
Clear definitions of relevant variables, the specific group being studied, and predicted outcomes
Which step involves writing a clear and concise answer to the research question?
Formulating the hypothesis
How can one identify variables in a hypothesis?
By writing a simple prediction in if...then form
What is the variable you measure to observe the effect of the independent variable?
Dependent variable
Which statement best describes the null hypothesis?
It states there is no significant difference or effect.
Why is selecting appropriate methods for testing the hypothesis important?
To align with the study objectives.
What is a common expectation when creating a research hypothesis?
Making changes as data is collected.
In hypothesis testing, what role does real-world evidence play?
It helps in determining how different factors are connected.
What is the importance of clearly articulating your research hypothesis before testing?
To frame both a null and an alternative hypothesis effectively.
What is the purpose of discussing whether to reject or fail to reject the null hypothesis in the context of hypothesis testing?
To determine if the results support the alternate hypothesis
When presenting research results in academic papers, what is the common practice regarding the alternate hypothesis?
The results are interpreted as supporting the alternate hypothesis
Why is hypothesis testing not designed to prove or disprove anything?
To avoid making definitive conclusions
What do researchers typically focus on when discussing research results in statistics assignments?
The conclusion drawn from rejecting the null hypothesis
Why do researchers rarely use the terms 'reject' or 'fail to reject' when presenting research results in academic papers?
To simplify the language for readers
What do researchers generally refer back to when stating whether their research results support their initial hypotheses in academic papers?
The alternate hypothesis
What is the purpose of using census data as a potential data source?
To include data from various regions and social classes
How does a statistical test determine if differences between groups are significant?
By comparing within-group variance to between-group variance
What does a low p-value indicate in a statistical test?
Low chances that differences occurred by chance
Why is the choice of statistical test important?
To select the appropriate test based on data variables and level of measurement
In hypothesis testing, what does a one-tailed t-test help determine?
An estimate of the difference in average height between men and women
When is it likely that any difference measured between groups is due to chance?
Low p-value and high within-group variance
