The first step in the research design is observing and explaining occurrences. The explanation for the research may be presented in the form of a question or as a hypothesis. The collection the information in quantitative research is what differentiates it from other types. Quantitative research is focused specifically on numerical information. Due to the fact that the research requires its conductor to use mathematical analysis to investigate what is being observed, the information collected must be in numbers.
The final step of the research revolves around using mathematics to analyze the ‘data’ collected. This is done with statistics. After statistical analysis of the results, a comprehensive answer is reached, and the results can be legitimately discussed and published. Quantitative experiments also filter out external factors, if properly designed, and so the results gained can be seen as real and unbiased.
There are numerous methods for conducting quantitative researches. To quantify data and generalize results from a sample to the population of interest, to measure the incidence of various views and opinions in a chosen sample and can sometimes be followed by a qualitative research which is used to explore some findings …show more content…

Qualitative research is generally exploratory in nature; it may be preceded of followed by quantitative investigation. Qualitative research generally involves individuals or small samples, these small samples may be carefully selected, and they may not be representative of the population as a whole, but that is not necessarily an issue, because the value of qualitative research derives from authentic and case specific detail that it can encompass. The information obtained is potentially richer and deeper than that described in numbers and statistics, and can take advantage of many subtle ways of using language to express opinions, experiences and feelings. On the other hand these factors may mean that it is less easy to compare different cases and arrive at generalized

It’s a quantitative method that is specifically used in psychology researches and it examines whether two variables such as events, behaviuors, properties, and characteristics are casually related. In other words, it is a scientific and systematic approach to research, in which the researcher can manipulate and control the variables i,e an independent variable is manipulated and the dependent variable is measured and it could be called a true experiment. The main advantage of this method is that it allows us to determine and regulate cause and effect, and further it allows us to control the effects of extraneous variables. Experimental method involves some kind of measurement and a mathematical calculation is frequently involved.

Introduction Qualitative research are those kind of researches that an outcome is obtained without the application of statistical methods of data analysis (Strauss and Corbin, 1990 cited in Golafshani, 2003). However, the qualitative research takes a direct approach, where the researchers arrive at a conclusion through the observation of events as they occur naturally without external interferences (Golafshani, 2003).

The researchers look for the most crucial data which is inevitable for the research. Generally there are three kinds of approaches or research methods namely Qualitative, Quantitative and Mixed. These methods are used to gather data and resolve issues that emerge during the process of data gathering. The researcher can bring forward his findings either in the form of quantitative or qualitative or mixed research methodologies only when the data is collected based on the preliminary data gathering process and the secondary data gathering process.

In quantitative research, variables are identified and defined, and then relevant data is collected from study participants. A strength of this type of research is that the data is in numeric form, making it easier to interpret. It also studies the relationship between independent and dependent variables and can address questions such as does a relationship between variables exist, what is the direction of the relationship, how strong is the relationship between the variables, and what is the nature of the relationship. To be able to discover and answer the cause-and-effect relationship is a strength of quantitative research. Lastly, in quantitative research, the study can either be experimental or nonexperimental, meaning clinical trial or observational study, allowing for different types of research studies to be conducted.
