The Meaning of Quantitative and Qualitative Research
Quantitative and Qualitative are two different forms of research that complement each other either from a numerical standpoint or a descriptive one. Quantitative research comes from a numerical perspective and qualitative research comes from more of a descriptive perspective, though they cannot be described with these specific terms, they need to be elaborated on to get more of an overall understanding.
Quantitative research expresses data in a numerical fashion and its main focus is to supply information and to determine relationships between variables (Guts, 2014). It is the most widely used research because it gives hard results and is quite easy to understand (Guts, 2014). Quantitative research can shape our behavior. For example, wearing a seatbelt in the car. People wear their seatbelts in the car because one, it is the law. Two, it became a law because of research that has been done, saying that wearing seatbelts protects the body more effectively when in car accidents than not wearing a seatbelt. The data is expressed numerically by showing statistics on people’s health when they have been in an accident either with a seatbelt on or off. Quantitative research is helpful when learning about unknown facts such as the importance of wearing a seatbelt.
The most popular method of quantitative research is an experiment, which gives casual information and hard numbers (Guts, 2014). Experiments are easy to understand, and provide accessible information that helps predict human behavior (Guts, 2014). In experiments, researchers manipulate variables using experiment and control groups. (Guts, 2014). An experiment includes independent and dependent variables. An independent variable is something that can be manipulated, which the researcher would call the control group. The dependent variable is the behavior the researcher is trying to calculate or the experimental group (Guts, 2014). A reason to keep hydrated is a good example of quantitative research. Because of quantitative research, we know that we can only live around two to three days without water or being hydrated. It gives simple data to comprehend which helps people actively stay hydrated to stay healthy.
Quantitative research can be highly effective. A strength of quantitative research is that the data is represented numerically, which makes it easier to understand. You can also repeat or replicate the data meaning that an experiment can take place more that one time. Essentially, there is a cause and effect application being applied. This allows for the data to be predictable, which means the researcher can interpret what is going to happen between the control and experimental group.
Quantitative research can advance the field of psychology because it can assist in diagnosing a patient or help to decide which medicine best suits a patient. Such as, the ability to indicate which medicine is suited in order to help control...
