This means that results in quantitative research may differ from real world findings. Therefore, it is quantitative research. Edeh Samuel Chukwuemeka ACMC, is a Law Student and a Certified Mediator/Conciliator in Nigeria. One way of minimizing the weaknesses of a quantitative research study is adopting a mixed methods research methodology. The pre-test influences the outcomes of the post-test. Because participants are placed into groups based on their initial scores, its hard to say whether the outcomes would be due to the treatment or statistical norms. Because there are already systematic differences between the groups at the baseline, any improvements in group scores may be due to reasons other than the treatment. 
Great patience is therefore needed in carrying out a quantitative research. 
For example, because Newtons laws of motion have been verified by countless experiments, we can use them to develop complex models for predicting how objects will behave in different situations. 3. This will make it impossible to use the data in any meaningful way. The survey can also be easily repeated and you can reliably track changes over time. Quantitative research is difficult, expensive and requires a lot of time to perform the analysis. But to know what strategies are applied by the manager to motivate the employee or on what parameters the employee does not feel motivated (if responded no), the researcher has to ask broader questions which somewhat has limited scope in close-ended questionnaires.

Nurse Res. Also, some respondents might demand to be paid before giving their inputs to such a research. A large sample size counters testing, because results would be more sensitive to any variability in the outcomes and less likely to suffer from sampling bias. A sample size formula can be used to calculate the appropriate sample size based on factors such as population size, the margin of error, and confidence level. The role of qualitative research in broadening the evidence base for clinical practice. 8. You could also compare this data with other areas to see which has the highest average income levels. The target population, in this case, is the women belonging to the said age group, with both professional and non-professional backgrounds, residing in Delhi. Other methods involve using formulas to estimate sample size. Also see: Advantages and Disadvantages of quantitative and qualitative Research. Generalisation of the views of a section of the population might not be the best as their views may be biased. Realism, subjectivism and the paradigm wars Now we have defined quantitative research, it is a good idea to compare it with qualitative research, to which it is usually put in opposition. Consideration is given to issues of sampling; the relationship between the researcher and subject; methodologies and collated data; validity; reliability, and ethical dilemmas. If your audience is large (across multiple locations, or across countries) or if you have a smaller audience but want them to complete your survey in their own language, quantitative research is the way to go. That is, it tries to establish a cause-effect relationship between the various variables under study. This type of research is planned carefully in order to ensure complete randomization and correct designation of control groups(Morgan 1980). When deciding between a quasi-experimental design and a randomized control trial for your research, it is important to consider the strengths and weaknesses of each option. Here are a few of the common methods used: Survey research Survey research entails gathering data from people interactively. The survey methodologies start with a few recommendations for designing a good survey, such as (1) the survey form should satisfy the objectives of the research, (2) there should be an appropriate (but not very long) length of questionnaires coving all essential parts, (3) questions should convey a single thought at a time, (4) language Every research methodology consists of two broad phases namely planning and execution (Younus 2014). Despite applying an appropriate sampling plan representation of the subjects is dependent on the probability distribution of observed data. Quantitative researchers are concerned with how much and how many, but their methods dont allow them to understand why something happens. Foundations of quantitative research methods 1.2.1. When you need to gather a large amount of information from a group of people, there are many ways to do so. Fourth is that in quantitative research, there is a possibility of an improper representation of the target population. For example, if you want to know what people think about a particular topic, then qualitative research would be best; but if you want to determine how many people are aware of a particular issue, then quantitative research would be better. This paper examines the controversy over the methods by which truth is obtained, by examining the differences and similarities between quantitative and qualitative research.
