A marketing research firm is conducting a study to determine if there is a relationship between an individual's age and the individual's preferred source of news. The research firm asked 1,000 individuals to list their preferred sources for news; newspaper, radio, and television, or the Internet. The accompanying results were obtained. At the 0.01 level of significance, can the marketing research firm conclusion that there is a relationship between the age of the individual and the individual's preferred source for news? Determine the null and alternative hypotheses Calculate the test statistic Calculate the p-value Do you accept or reject the null is there significant evidence? Can the marketing firm conclude that there is a relationship between age and preferred news source?
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.
