I would like to check my answer please for the ones I underline. Dr. Banner wants to conduct a study that focuses on a population of children suffering from a very rare genetic disorder. He has only been able to identify three individuals as potential study participants. The ideal research method for this study would be Descriptive research? A researcher has hypothesized that listening to music while studying will help to improve students' test scores. The researcher collects data and discovers a positive correlation between the two variables. However, the researcher cannot conclude that the music causes improved test scores, because the correlation could have been produced by the presence of a Correlational research? Professor Evans is getting ready to conduct an experiment. He explains to his study participants the nature of the study, including everything that might be expected, and tells them that they can withdraw from the study at any time. Professor Evans is obtaining their Informed Consent? A researcher is conducting a study over a 5 year period. When he begins the study, he has 500 participants. By the end of the study, only 322 subjects are still participating. This is an example of Experimental research?
Correlation
Correlation defines a relationship between two independent variables. It tells the degree to which variables move in relation to each other. When two sets of data are related to each other, there is a correlation between them.
Linear Correlation
A correlation is used to determine the relationships between numerical and categorical variables. In other words, it is an indicator of how things are connected to one another. The correlation analysis is the study of how variables are related.
Regression Analysis
Regression analysis is a statistical method in which it estimates the relationship between a dependent variable and one or more independent variable. In simple terms dependent variable is called as outcome variable and independent variable is called as predictors. Regression analysis is one of the methods to find the trends in data. The independent variable used in Regression analysis is named Predictor variable. It offers data of an associated dependent variable regarding a particular outcome.
