We may prefer not to think of 10,00,100 and 10,00,102 as crucially different values, but instead as nearby points on an approximate continuum. The results of convenience sampling may be very good in some cases and highly biased (favor certain outcomes) in others. Number each department, and then choose four different numbers using simple random sampling. The weights (in pounds) of their backpacks are 6.2, 7, 6.8, 9.1, 4.3. Just as there is variation in data, there is variation in samples. Work collaboratively to determine the correct data type (quantitative or qualitative). The continuous variable can take any value within a range. Self-selected samples: Responses only by people who choose to respond, such as call-in surveys, are often unreliable.
