What is the difference between qualitative data and quantitative data? 3. What is the difference between discrete data and continuous data? 4. If an experiment produces data that is continuous in nature, must the data also be quantitative or can it be qualitative? 5. Define descriptive statistics. 6. Point out the difference between a nominal scale and an ordinal scale. II. Variable type: Determine the type of variable is Categorical or Numeric. Also if it is Discrete or Continuous 1.
