WISQARS NVDRS Practice Questions

If you are a first-time WISQARS NVDRS user, please take time to answer the following practice questions to familiarize yourself with the system’s various options and outputs. Check your results against our answers below. For all practice questions, use the Abstracter Assigned Mode of Determining a Manner or Cause of Death.
