Find the t value(s) for each of the following cases. (Round your answers to three decimal places.) (a) upper tail area of 0.025 with 16 degrees of freedom 2.120 (b) lower tail area of 0.05 with 54 degrees of freedom -1.674 (c) upper tail area of 0.01 with 32 degrees of freedom 2.449 (d) where 90% of the area falls between these two t values with 29 degrees of freedom and both t values are the same distance from 0 smaller value larger value (e) where 95% of the area falls between these two t values with 45 degrees of freedom and both t values are the same distance from 0 smaller value larger value
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.
