Choose any dataset uploaded in the "Datasets" folder which contains at least two variables. (25) (a) Consider any two variables from your dataset. You should have a series of data for each variable. Try to work with a bigger sample size and select data where the variables have some causal relationship. Like one is a dependent and the other is an independent variable.
