Question

5. Many sciences rely on observation instead of (or in addition to) designed experiments. Compare the data quality issues involved in observational science with those of experimental science and data mining

Answer 1

Answer and Explanation:

The quality of the data can be higher in observational or experimental studies depending on the subject being researched.

In a way, we can think that experimental studies have better data quality, due to the design of the experiment and the control of the study groups and the variables that are not possible to be established in the obsevational experiments.

However, in the case of studies of abstract subjects, the experimental study ceases to provide high quality activities, and it is necessary to establish an observational study so that efficient data can be promoted.

Answer 2

Data obtained from experimental studies is more reliable than data obtained from observational studies.

Science is empirical in nature. However, some sciences rely on observational rather than experimental studies. Experiments establish cause and effect relationships between variables.

Cause and effect relationships can not be established from observational studies. Data obtained from experimental studies is more reliable than data obtained from observational studies.
