Researcher uses tools, such as questionnaires or equipment to collect numerical data. Data is in the form of words, pictures or objects. Data is in the form of numbers and statistics. Qualitative data is more 'rich', time consuming, and less able to be generalized. Quantitative data is more efficient, able to test hypotheses, but may miss contextual detail. Researcher tends to become subjectively immersed in the subject matter. Researcher tends to remain objectively separated from the subject matter.
Qualitative versus Quantitative Research: Key Points in a Classic Debate. James Neill Last updated: Everything is either 1 or 0" - Fred Kerlinger. The aim is a complete, detailed description.
Main Points Qualitative research involves analysis of data such as words e. Quantitative research involves analysis of numerical data. There are usually two groups in this category - learners that already have the data and are contemplating how to leverage it, and those that have in mind a way to collect it. My advice for the second group is to be cautiously optimistic about the collection of data through Survey Monkey, and other instruments.
Often participants are less willing to participate than originally planned, which means that response bias will also have to be something that you discuss in your dissertation. If your research involves a field experiment, successfully encouraging subjects to participate will be an essential component of the success of your research.
This is one of the easiest challenges to remedy, as your methodologist, and related studies, should guide your selection of statistical methods. Of course, you will need to explain why you used a particular method in your dissertation. Finally, what the numbers actually "tell us" can be materially different from what we expected. The results can either be inconclusive, or they may actually reveal that the opposite of our assumptions was actually true.
In this case, would it be possible for you to leverage this new, surprising, knowledge in some way? For example, if extra instruction actually lowers test scores in an educational setting, then are the courses worth the extra resources for the organization?
Hopefully, this list of considerations, offered as just a start of some of the challenges of a quantitative dissertation, will generate some thought at just the right time for you in the doctoral process!

Characteristics of Quantitative Research Your goal in conducting quantitative research study is to determine the relationship between one thing [an independent variable] and another [a dependent or outcome variable] within a population. 7 Characteristics of Quantitative Methods. Seven characteristics discriminate qualitative methods of research from qualitative ones. Data gathering instruments contain items that solicit measurable characteristics of the population (e.g. age, the number of children, educational status, economic status).
Quantitative research designs are either descriptive [subjects usually measured once] or experimental [subjects measured before and after a treatment]. A descriptive study establishes only associations between variables; an experimental study establishes causality. Quantitative research deals in numbers, logic, and an objective stance. Quantitative Methods Toggle Dropdown. Characteristics of Qualitative Research Below are the three key elements that define a qualitative research study and the applied forms each take in the investigation of a research problem. The Design. Naturalistic -- refers to.
