💢Quantitative research
Kinds : 1⃣ experimental research
2⃣ nonexperimental research
🌀 Experimental Research
research in which the investigator manipulates one or more independent variables (the treatment) and observes the effect on one or more dependent variables.
🌀 Nonexperimental Research
1⃣ Ex post facto research ➡️ a type of research that attempts to determine the causes for, or the consequences of, differences that already exist in groups of individuals .
⬇️
✔️ the researcher does not manipulate the independent variable.
✔️ it has already occurred in the natural course of events.
2⃣ Correlational Research ➡️ research that attempts to determine the extent and the direction of the relationship between two or more variables.
⬇️
✔️the investigator gathers data from a group of individuals on two (or more) variables and then seeks to determine if the variables are related (correlated).
✔️ the relationship between the variables is expressed by a statistic called the coefficient of correlation.
✔️a positive correlation shows that high values on one variable are associated with high values on the other.
✔️a negative correlation means that high scores on one variable are associated with low scores on the other variable.
✔️It can range from +1.00 (perfect positive) through 0 indicating no relationship to -1.00, a perfect negative relationship.
3⃣ Survey Research ➡️ surveys use instruments such as questionnaires and interviews to gather data from groups of individuals.
