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.

In a cohort of a population, 10% of individuals die each year (e.g. if 100 individuals are alive at the beginning of the year, 10 will die). Try plotting such a “curve” on a graph with (i) an arithmetic y-axis, and on a graph with (ii) a logarithmic y-axis (e.g. make two different graphs of this data, one with an arithmetic y-axis, and one with a logarithmic). Make sure to label your axes appropriately. What type of survivorship curve is this?
