It can answer what, where, when, and how, but not why questions (those are answered in qualitative research). The researcher does not control or manipulate the variables. They just observe and measure them. Goals of descriptive research: The goal of descriptive research is to understand the current status of an identified variable. When to use descriptive research Descriptive research is used to identify categories and trends, form hypotheses, arrange comparisons, confirm existing phenomena, and outline sample characteristics.  Descriptive if... Levels of Satisfaction, Factors Affecting, Impacts and Perceived Effects CORRELATIONAL RESEARCH The correlational research method examines the relationships between different subjects and variables without the researcher controlling or manipulating any of them. It is focused on relationships between fixed variables. Correlational research relies on the scientific method and hypotheses. Goals of correlational research The goal of correlational research is to identify variables that have some sort of relationship to the extent that one creates a change in the other. When to use correlational research Correlational research is used to gather data quickly from natural settings so you can generalize findings to a real-life situation.  Kinds of correlation The relationship between two variables you are studying vary!

Goals: To show which among the two choices is a “better choice” When to use: Used if you want to weigh the differences of two choices’ characteristics, features or behavior. EXPERIMENTAL RESEARCH is a study conducted with a scientific approach using two sets of variables. The first set acts as a constant, which you use to measure the differences of the second set. Goals of experimental research: The goal of experimental research is to prove or disprove a specific hypothesis. It uses the scientific method to establish the cause-effect relationship among a group of variables. When to use experimental research: Use experimental research when you need to compare two or more groups that are experiencing different conditions.  KINDS OF QUALITATIVE RESEARCH Read this!

Historical  Narrative RESEARCH aims to explore and conceptualize human experience and story as it is represented in textual form.. Goals of narrative research: The primary objective of the study is to extract meaningful context based on documented experiences. When to use narrative research: Use narrative research when you want to conduct a study focusing mainly on the nature of the story and life experience told by the participants.  Phenomenological This focuses on subjective lived experiences of the participants in order to understand a phenomenon. This research is usually conducted to study a unique phenomenon’s effect to participants. Goals of phenomenological research: The primary aim of phenomenological research is to gain insight into the experiences and feelings of a specific audience in relation to the phenomenon you’re studying. When to phenomenological research: This design is especially useful for topics in which the researcher needs to go deep into the audience’s thoughts, feelings, and experiences.  CASE STUDY Allows the research to have an intensive analysis of the phenomenon. Goals of case study research: To accurately describe the case through an in-depth examination of a single person or single institution. When to use case study research: if you are after a thorough interview, observation and documentation to a specific phenomenon experienced by an individual/institution.  grounded theory This kind of research intends to explain a phenomenon through developing a theory. In comparison with researches that are about lived experiences, this research seeks to provide explanation behind those. Goals of grounded theory research: The goal of this research is to generate a carefully formulated ‘theory’ behind a phenomenon based on the respondent’s answers. When to use grounded theory: Use this approach if you are after coining a new theory/belief after conducting the study.  ethnographic It is a kind of research that focuses on the study of group of people in a particular environment Goals of ethnographic research: The goal of this research is to understand why and how a certain group of people act. Also to have an understanding about culture, behavior, social beliefs and practices When to use ethnographic research: Use experimental research when you need to know deeply about a group’s culture, behavior, social beliefs and practices in their area.  HISTORICAL Concerned with the identification, evaluation and synthesis of past event data. Goals of historical research: Aims to understand present patterns and anticipate future choices through clearly relating the past event data which are from reliable sources, documents and reports. When to use historical research: Use this study if you want to connect or relate different patterns from the past, present and future.
