Write your responses to each of the 3 questions in the space below, using complete sentences. You are interested in two variables: ‘grit’ (the ability to persevere when difficulties arise) and ‘sense of purpose’ in life. Each variable is measured on an interval-levell scale with possible scores from 10 to 50. What is a formally stated research question involving those two variables that could be tested by calculating the r correlation coefficient? If there was a negative correlation between grit and sense of purpose, what does that tell you about the patterns of scores in the two variables? If there was a positive correlation between grit and sense of purpose, what does that tell you about the patterns of scores in the two variables?
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.
