The Government of Pakistan publishes information about Corona virus Cases in Pakistan. The following contingency table provides a cross classification of cities of Pakistan and Covid-19 Stats. City Covid-19 Stats Confirmed Cases Active Cases Deaths Recoveries AJK 271 95 6 170 Balochistan 4514 2900 49 1565 Islamabad 2898 2694 30 169 KPK 10485 7030 482 2973 Punjab 27850 20194 540 7116 Sindh 29647 14554 503 14590 At the 5% significance level, do the data provide sufficient evidence to conclude than an association exists between cities and Covid-19 stats?
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.
