Choose any two easily recordable explanatory and response variables that you wish to analyse regarding biostatistics.

Briefly explain the relationship you believe would exist between your chosen variables of interest.

Solutions

Expert Solution

Let us consider the data

The correlation matrix is given by:

The value of correlation coefficient is lies between -1 and 1. if the correlation coefficient is positive then there exist a positive relationship between the variable. i.e., one increases the other also increase. if the value is negative then there exist a negative correlation. i.e.,one increases the other is decreases. the relationship between the variable is clear from the above table. if the value is higher than 0.5 or less than -0.5 then the correlation is severe.
