why randomize an experiment why is a randomized trial a weak causality which is a strong causal argument for the use of randomization in randomized controlled trials how does randomization affect results of a study what is the difference between randomization and causality what is the argument that randomization increases the score when randomization is used to compare a treatment and a placebo, the results will be the same. what is the difference between a study and a randomized trial how is randomization used which argument is most likely against randomization? do randomization and randomisation cause causality does randomization guarantee nothing what is the argument for weak causality does randomization guarantee a certain outcome does randomization allow for any causality can randomization cause univariate effect does randomization affect the outcome of an experiment? can the randomization argument be used to prove causality of an experiment which theory of randomization is best argued against why was the placebo and treatment randomized?
