Which of the following is the best method of doing randomization?

Randomization is best done by using a table of random numbers. Must know: Randomization is the hea of the controlled trial study. Randomization is a statistical procedure that assigns research paicipants by chance, rather than by choice, to either the investigational group or the control group of the clinical trials. The goal of randomization is to eliminate bias and produce comparable groups in terms of general paicipant characteristics, such as age or gender, and other key factors that affect the probable course the disease would take.
