What are the similarities between social sciences natural sciences?

Sociologically, Social Sciences studies interactions and relation between different groups of which society is made up of, and how they are affected as members of society.

Natural Sciences studies causes of Nature's Reaction, Effects of phenomenon which occurs (beyond mere human imagination). The similarities between Scocial Sciences and Natural Sciences is mainly the Research Methods applied by both sides which include:

The use of theory so as to provide explanation to events and happenings in society, and the methodology used are:

a. Concept, e.g. Name, tag etc

b. Variable (this is a concept but exists in divers forms).

c. Proposition: a statement about one or more variable.

d. Hypothesis: a tentative statement that assumes the existence of relationship between two or more variables subject to test by means of relevant data.

e. Laws: laws are gotten out of theory, whereby thories are obtained from tested and confirmed hypothesis

f. Methods: these are techniques of aobtaining relevant data for the purpose of hypothesis.

These are my own little point of view, opened to criticism and modifications.

Thank you.
