Aparticularly statistically curious clickbait website writer noticed that all the cool creative people he knows are also very anxious or neurotic. To test his hunch, he find 5 volunteer friendsand gives thema surveyon neuroticism (1-5 point scale) and a puzzle he found on the internet that supposedly is solved faster by more creative peopleand measures how long it takes each person to solve in seconds. The data areXneuroticism: 3.6, 1.5, 2.85, 2, 4.9Xcreativity: 32, 62, 123, 15, 4 A. Identify the appropriate statistical measure to use. B. Conduct the test. Make a decision about the null hypothesis, interpret your results and calculate effect size if applicable. At ?=.05,is the writer right about his hunch?
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.
