The empirical method of study is based on a. guesswork b. practice c. observation d. statistics

Observation                              

Explanation:

Empirical studies is observational evidence-based analysis. It refers to a way of obtaining insight through directly and indirectly evaluation or practice. Empiricism views more than most types of work. It is possible to mathematically or subjectively evaluate empirical proof.

Research design in such studies varies depending on the area and the problem being examined. Several scientists combine theoretical and practical types of study to adequately respond to comments that can not be examined in laboratory conditions, especially in humanities and learning.

Thus, from the above we can conclude that the correct option is C.

odd consecutive integers are odd integers that follow each other. they have a difference of 2 between every two numbers. if n is an odd integer, then n, n+2, n+4 and n+6 will be odd consecutive integers. the first number in the pattern is always the variable on its own or in this case, "n". examples.
