Hypothesis types: Null hypothesis (states no relationship between variables) and Alternative hypothesis (predicts a relationship between variables).

Research types by purpose: Descriptive research (describes characteristics of a population), exploratory research (investigates a problem and provides insights), explanatory research (seeks to identify the cause-effect relationship).

Quantitative vs. Qualitative Research: Quantitative research focuses on numerical data and statistical analysis to draw conclusions, while qualitative research concentrates on non-numerical data like words, observations, and interviews to explore concepts.
