PRACTICAL RESEARCH 2 Nature and Inquiry of Research · Describe the Characteristics, strengths, weaknesses, and kinds of quantitative research. · Illustrate the importance of quantitative research across the fields · Differentiate the kinds of variables and their uses  Identify the characteristics, strengths, weaknesses, and kinds of research Learning Objective Differentiate quantitative and qualitative research Enumerate the different characteristics of quantitative research and its advantages and disadvantages PRACTICAL RESEARCH 2  CHARACTERISTICS OF RESEARCH LARGE SAMPLE SIZE To obtain more meaningful statistical result, the data must come from a large sample size. PRACTICAL RESEARCH 2  CHARACTERISTICS OF RESEARCH OBJECTIVITY Data gathering and analysis of results are done accurately, objectively, and are unaffected by the researcher’s intuition and personal guesses. PRACTICAL RESEARCH 2  CHARACTERISTICS OF RESEARCH CONCISE VISUAL PRESENTATION Data is numerical which makes presentation through graphs, charts, and tables possible and with better conveyance and interpretation. PRACTICAL RESEARCH 2  CHARACTERISTICS OF RESEARCH FASTER DATA ANALYSIS The use of a statistical tools gives way for a less time-consuming data analysis. PRACTICAL RESEARCH 2  CHARACTERISTICS OF RESEARCH GENERALIZED DATA Data taken from a sample can be applied to the population if sampling is done accordingly, i.e., sufficient size and random samples were taken. PRACTICAL RESEARCH 2  CHARACTERISTICS OF RESEARCH FAST AND EASY DATA COLLECTION Quantitative research uses standardized research instruments that allow the researcher to collect data from a large sample size efficiently. PRACTICAL RESEARCH 2  CHARACTERISTICS OF RESEARCH RELIABLE DATA Data is taken and analyzed objectively from a sample as a representative of the population, making it more credible and reliable for policymaking and decision making. PRACTICAL RESEARCH 2  CHARACTERISTICS OF RESEARCH HIGH REPLICABILITY The Quantitative method can be repeated to verify findings enhancing its validity, free from false or immature conclusions. PRACTICAL RESEARCH 2  Advantages of Quantitative Research 1. Very objective 2. Numerical and quantifiable data can be used to predict outcomes. 3. Findings are generalizable to the population. 4. There is conclusive establishment of cause and effect 5. Fast and easy data analysis using statistical software. 6. Fast and easy data gathering 7. Quantitative research can be replicated or repeated. 8. Validity and reliability can be established PRACTICAL RESEARCH 2  Disadvantages of Quantitative Research 1. It lacks the necessary data to explore a problem or concept in depth. 2. It does not provide comprehensive explanation of human experiences. 3. Some information cannot be described by numerical data such as feelings, and beliefs. 4. The research design is rigid and not very flexible. 5. The participants are limited to choose only from the given responses. 6. The respondents may tend to provide inaccurate responses. 7. A large sample size makes data collection more costly. PRACTICAL RESEARCH 2  Kinds of Quantitative Research DESCRIPTIVE DESIGN is used to describe a particular phenomenon by observing it as it occurs in nature. There is no experimental manipulation, and the researcher does not start with a hypothesis. The goal of descriptive research is only to describe the person or object of the study. An example of descriptive research design is “the determination of the different kinds of physical activities and how often high school students do it during the quarantine period.” PRACTICAL RESEARCH 2  Kinds of Quantitative Research THE CORRELATIONAL DESIGN identifies the relationship between variables. Data is collected by observation since it does not consider the cause and effect, for example, the relationship between the amount of physical activity done and student academic achievement. PRACTICAL RESEARCH 2  Kinds of Quantitative Research EX POST FACTO DESIGN is used to investigate a possible relationship between previous events and present conditions. The term “Ex post facto” which means after the fact, looks at the possible causes of an already occurring phenomenon. Just like the first two, there is no experimental manipulation in this design. An example of this is “How does the parent’s academic achievement affect the children obesity?” PRACTICAL RESEARCH 2  Kinds of Quantitative Research A QUASI-EXPERIMENTAL DESIGN is used to establish the cause-and-effect relationship of variables. Although it resembles the experimental design, the quasi-experimental has lesser validity due to the absence of random selection and assignment of subjects. Here, the independent variable is identified but not manipulated. The researcher does not modify pre-existing groups of subjects. The group exposed to treatment (experimental) is compared to the group unexposed to treatment (control): example, the effects of unemployment on attitude towards following safety protocol in ECQ declared areas. PRACTICAL RESEARCH 2  Kinds of Quantitative Research EXPERIMENTAL DESIGN like quasi- experimental is used to establish the cause-and-effect relationship of two or more variables. This design provides a more conclusive result because it uses random assignment of subjects and experimental manipulations. For example, a comparison of the effects of various blended learning to the reading comprehension of elementary pupils.
