ature of Inquiry and Research Learning Competencies: ❏ Describes characteristics, strengths, weaknesses, and kinds of quantitative research ❏ Illustrates the importance of quantitative research across fields ❏ Differentiates kinds of variables and their uses Characteristics, Strengths, Weaknesses, and Kinds of Quantitative Research  Characteristics of Research Research is the acquisition of new knowledge through purposive, organized, and designed program. Basic Research - conducted solely to come up with a new knowledge or to have a fuller understanding of a particular subject for its own sake. Applied Research - is done to find an application of the knowledge, whether it it is old or new. Aims of Research & Sources of Research Topics ❏ Produce new ❏ Science ❏ Education knowledge or ❏ Business information ❏ Politics ❏ Utilize new knowledge ❏ Medicine ❏ Law ❏ Validate existing ❏ Computer Science knowledge ❏ Sports ❏ Improve the ❏ Humanitie investigator/researcher ❏ STEM ❏ ABM  Kinds of Research Method ❏ Qualitative Research aims to gain deeper awareness of human behaviour. It investigates the why and how of decision making not just what, where and when. ❏ Quantitative Research also known as empirical research, is a type of research where relations are established through collection of numerical data which are analyzed to derive a generalization. It is a systematic scientific analysis of data and their relationships. It specifically refers to tests experiments that yield quantifiable values that can be analyzed using statistics, figures, and mathematical models to provide information that may be used to aid in decision making Continue…. ❏ It is usually more objective as the accumulated data is submitted to statistical analysis. ❏ It often depicts a study answering the “what” and “how many/much” questions. ❏ It is often concerns with finding evidence to either support or contradict an idea or hypothesis ❏ Hypothesis: a predicted answer to a research question. For example the research might want to propose that if young kids are exposed to internet games, it will adversely affect their performance in school. Types of Quantitative Research Design ❏ Descriptive Research a type of research design that aims to systematically obtain information to describe a phenomenon, situation, or population. More specifically, it helps answer the what, when, where, and how questions regarding the research problem rather than the why. ❏ Correlation Research looks into the degree of association between variables. It considers the extent to which the differences between Variables are related to the differences in another variable or variables. ❏ Causal Research looks into the cause-and-effect relationship between variables that is, as prices increases, the demand decreases. ❏ Experimental Research is one where a group of respondents are randomly selected to undergo a particular researcher-imposed treatment to determine the effect of such treatment. For example, a group of students may be subjected to learning using technology, while the regular class uses the ordinary way of learning. The performance of the experimental group is then compared with the performance of the other group to determine the extent to which the use of technology affected the amount of learning that took place. ❏ Historical Quantitative Research makes use of historical data to predict that behavior of a variable. It traces patterns from the historical data. For instance, a study can be made on the sales of a particular type of milk tea over a six-month period to predict the probable amount of sales in the next period.  Strengths of Quantitative Research ❏ Data collection using the quantitative design is relatively faster and easier to do because it could speedily generate accurate, precisem and credible results. ❏ Data analysis is done through the use of statistical software, which is proven more effective in validating constructed hypotheses and theories. ❏ The results are more objectives and are free from personal biases of the researcher. ❏ Quantitative results are more credible and reliable with people in authority. Weaknesses of Quantitative Research ❏ Quantitative study may be too technical for average readers to comprehend. ❏ The emphasis on statistical significance which may sometimes disregarded other aspects involved or can affect the study. ❏ The result might be too abstract and extensive for direct application to particular local conditions and personage. ❏ The result of the study may also be too limited as they only provide numeric interpretations rather than detailed narrative accounts of an individual’s insight. The Importance of Quantitative Research Across Fields  Quantitative Research Across Fields Different types of quantitative research are used in various disciplines: ❏ Medical Field where blood levels contain a measurable amount of white and red blood cells an electrolytes. Rather than physical counting each sample, tat data collection process is automated using a computer. ❏ Household Census where Philippine Statistics Authority (PSA) determine the number of residents in every household in the entire Philippines. The findings of this survey could generate more detailed profile of the Filipino people, which could possibly be used y the government to determine the following year’s national budget among other things. ❏ Market Research to determine customer satisfaction or dissatisfaction. ❏ Finance to determine the economic growth and overall performance. ❏ Education study the student’s academic performance rating. ❏ Disaster Management hit areas whose people are most at risk and  Differentiates Kinds of Variables and their Uses The Use of Variables in Research Variable is an object idea, feeling, time period, or any other type of category which can be measured. Characteristics of a Variable ❏ They have a prescriptive period/duration when they start and stop. ❏ They may have a pattern such as daily, weekly, and monthly. ❏ They are detailed though the summary is through and profound. ❏ There may be dormancy which is the time gap between measuring dependent and independent variables because some things do not take effect right away. Types of Variables ❏ Independent Variable is the probable cause of an event. It is independent of everything that transpires and is the variable that is controlled by the researcher since he or she may manipulate to determine if it will affect change on the dependent variables. ❏ Dependent Variable the outcome variable, is the outcome of the study. It is affected by the independent variable. It is something that depends The Relationship Between IV and DV ❏ Independent variables cause a change in the dependent variable. It is not possible for dependent variable to cause a change in an independent variable. ❏ In the case of the dependent variable, its value or behavior is considered dependent, to an extent, upon the value of the independent variable but not the other way around. ❏ The independent variable is truly independent from the dependent. Its value does not change according to the value of dependent variable.
