How can you use “rdd” in a sentence? Here are some example sentences to help you improve your vocabulary:

Two survey research companies (Survey Methods, and Field Research Corporation, both of San Francisco, California) conducted RDD and preliminary eligibility screening of controls.
The RDD contractor also generated a batch of about 300 random numbers from marketing sources to increase the number of calls to households with women aged 65 years and older.
RDD was conducted from April 2000 to August 2001.
This seems unlikely given the high participation rates among those found to be eligible on the basis of RDD, but it is possible that there was some selection bias in women or households who were willing to answer the telephone call screening for eligibility.
Table 1shows participation rates for cases and controls, and the footnote gives details on the numbers and disposition of calls made through RDD.
