Comparison and Contrast of objectives, questions or hypotheses used in quantitative and qualitative articles

Qualitative vs. Quantitative

In comparing and contrasting the use of objectives, questions, or hypotheses in qualitative and quantitative research we learn the proper methods for creating research papers.

Qualitative objectives are subjective and non-measurable. There are no ways to accurately measure your objectives, therefore it makes it difficult to know when the objective has or has not been met. The results of qualitative objectives are debatable because the results are not defined. As such, qualitative objectives can not be used in certain applications. They can not be used for testing and other educational objectives.

Quantitative objectives are measured or measurable. Some things need to be measured to see if we have met our objective. There’s a way to measure and see if the objective has or has not been met. There is no debating on if we have or have not met the objective because we already know the answer from when we measured and defined the objective Comparison and Contrast of objectives, questions or hypotheses used in quantitative and qualitative articles.

Qualitative research questions include characteristics of the culture and nature of its members. It questions about the experiences and perspectives of individuals in the situations observed, and questions about lived experience, occurrences related to the idea or concept, and collective perceptions. If questions are included in the qualitative research, they tend to be broader and more global than questions in quantitative reports, they revolve around feelings, perceptions and rarely mention the population studied (Gray et al., 2017).

Quantitative research questions inquire about relationships among variables that the investigator is researching. a quantitative research question is likely to be a restatement of the research purpose. The questions usually relate to the study’s individual aims and objectives they’re specific to the purpose of the study.

It is said that qualitative hypotheses involve generating hypotheses rather than hypothesis testing as in the quantitative hypothesis. “Results from qualitative research have been assumed to apply only to the small groups studied, such that generalizability of the results to other populations is not expected. For this reason, qualitative research is considered to be hypothesis-generating, although some experts dispute this” (Qualities of Qualitative Research: Part I, n.d.).

The quantitative hypothesis involves making predictions about the expected relationships among variables and numeric estimates of population values based on all data collected. The testing of hypotheses uses statistical procedures in which the investigator draws inferences about populations from a study sample. There are two different forms of quantitative hypotheses:

•  A null hypothesis that makes a prediction that in the general population, no relationship or no significant difference exists between groups on a variable, in other words, “There is no difference (or relationship)” between the groups Comparison and Contrast of objectives, questions or hypotheses used in quantitative and qualitative articles.

There’s also a directional hypothesis. When the investigator makes a prediction about the expected outcome, basing the prediction on prior literature and suggests it may be a potential outcome (Creswell, 2014).

The two different styles of research are quite different from each other in that quantitative is still all about using data and statistics while qualitative generates questions about who, what, where, and why to answer and create research.
