What are the principal data sources in experimental and quasi experimental research

How does nonexperimental research differ from experimental research? Research which lacks a true independent variable which is manipulated by the experiment. Useful in situations where it is possible or not ethical to… manipulate the variable of interest.

Scientific investigation in which the investigator manipulates and controls one or more independent variables to determine their effects on the outcome dependent variable. Is qualitative research same as experimental research? No, it is not the same. Qualitative research is usually seen as the opposite of quantitative research, of which experimental research is a type of.

Qualitative research deals… with words, concepts and themes - often answering 'why - questions. It leads to better understanding of life experiences and is holistic in nature. Information is collected through individual or group focus group interviews, observation and unstructured observation.

Information is analysed through interpretation and the findings is often unique to a specific context in specific time and not supposed to be generalized to other contexts.

Quantitative research is based on logical positivism with strict rules. It usually deals with numbers and statistics. The research is supposed to be as objective a possible and the findings to be true in all contexts. Within this family of research experimental research is objective, systematic, controlled investigation to examine probability and causibility among selected independent and dependent variables for the purpose of predicting and controlling.

Elements of quasi experimental and experimental research? Experiments study the influence of one or more variable on another. They manipulate the first variable, or variables, which are called independent variables and study the impa…ct it has on the final variable, called the dependent variable.

The researchers can make causal conclusions based on the results. Quasi-experiments are those where the "independent variable" cannot be manipulated by the researchers. These include correlational studies where the researchers examine the relationships between two or more variables that already exist; and studies with subject variables, which are preexisting differences between the subjects or participants being studies and can therefore not be manipulated.

Quasi-experiments are still very useful and important, but no causal conclusions can be drawn from them. An experiment might study the effect of studying on test scores by having two groups of people study for different amounts of time and then write the same test.

The independent variable is the amount of time a person studied say, 1 hour or 5 hours and the dependent variable is their score on the test. The results might lead the researchers to conclude that studying increases tests scores.

A quasi-experiment might study the relationship between the scores on a test of early-birds and night-owls by having 10 of each group take a test.

The subject variable is whether the participant is an early-bird or a night-owl; the experimenter cannot manipulate this variable. The dependent variable is the score on the test.

If there is a difference between the groups' scores, the researcher can only say that night-owls and early-birds differ in their test scores. Give some examples of experimental research titles?
