Inferences Concerning Two Means If researchers want to compare two samples in terms of the mean scores using inferential statistics‚ they can utilize a confidence interval approach to the data or an approach that involves setting up and testing a null hypothesis. Whether two samples are considered to be independent or correlated is tied to the issue of the nature of the groups before data are collected on the study’s dependent variable. If the two groups have been assembled in such a way that

Reasoning: – Facts‚ Inferences‚ Judgments – Premises & Conclusion A fact is information that is verifiable‚ or can be “proven” to be true. How do we verify it? We observe it for ourselves by - looking out the window to see if it’s raining - touching a snake to see that it’s not slimy - tasting the soup to find out if it is salty Or we trust other people to tell us facts - a friend who says the class has been canceled - a newspaper reporter who describes an earthquake in

A researcher predicts that watching a film on institutionalization will change students’ attitudes about chronically mentally ill patients. The researcher randomly selects a class of 36 students‚ shows them the film‚ and gives them a questionnaire about their attitudes. The mean score on the questionnaire for these 36 students is 70. The score for a similar class of students who did not see the film is 75. The standard deviation is 12. Using the five steps of hypothesis testing and the 5% significance

Statistical mechanics or statistical thermodynamics[note 1] is a branch of physics that applies probability theory‚ which contains mathematical tools for dealing with large populations‚ to the study of the thermodynamic behavior of systems composed of a large number of particles. Statistical mechanics provides a framework for relating the microscopic properties of individual atoms and molecules to the macroscopic bulk properties of materials that can be observed in everyday life‚ therefore explaining
