All data that are the result of measuring are quantitative continuous data assuming that we can measure accurately. Besides simple random sampling, there are other forms of sampling that involve a chance process for getting the sample. Discrete data is a sort of numerical data that consists of full, concrete numbers that have particular and fixed data values that are determined by counting. Continuous information is information that falls into a continuous series. There are no strict rules concerning which graphs to use. The first sample probably consists of science-oriented students. a. This is completely natural. a. For example, suppose you have to do a phone survey.
