Respond clearly and thoroughly, yet concisely, to each of the following questions. Be sure to justify your response, when appropriate. A researcher selected a sample of 268 former sociology and psychology students from a list of all graduates of a university. A total of 17% of the sample of sociology and psychology students had earned graduate degrees as compared 14% of all graduates. In her calculations, the researcher obtained a Z score of 1.42. Is the difference statistically significant? Follow the five step model and state all important information at each step. Make sure to interpret the results in terms of the original research question
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.
