ELLE. R. - 12 – YOGORE Discussed by Sir Bryle P. Alim & Sir Kristopher Alan Tayag Characteristics of Quantitative Research High Replicability The Quantitative method can be repeated to Large Sample Size verify findings enhancing its validity, free from false or immature conclusions. To obtain more meaningful statistical result, the data must come from a large sample size. Advantages of Quantitative Objectivity Research Data gathering and analysis of results are done accurately, objectively, and are unaffected by the 1. Very objective researcher’s intuition and personal guesses. 2. Numerical and quantifiable - data can be used Concise Visual Presentation to predict outcomes. Data is numerical which makes presentation 3. Findings are generalizable to the population through graphs, charts, and tables possible and with better conveyance and interpretation. 4. There is a conclusive establishment of cause and effect Faster Data Analysis 5. Fast and easy data analysis using statistical The use of statistical tools gives way for a less software time-consuming data analysis. 6. Quantitative research can be replicated or repeated Generalized Data 7. Validity and reliability can be established 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. Disadvantages of Fast and Easy Data Collection Quantitative Research Depending on the type of data needed, collection its weaknesses: can be quick and easy. 1. It lacks the necessary data to explore a problem Quantitative research uses standardized research or concept in depth instruments that allow the researcher to collect data from a large sample size efficiently. 2. It does not provide comprehensive explanation of human experiences For instance, a single survey form can be administered simultaneously to collect various 3. Some information cannot be described by measurable characteristics like age, gender, numerical data such as feelings, and beliefs socio-economic status, etc. 4. The research design is rigid and not very flexible Reliable Data 5.

A large sample size makes data collection more Identifies relationships between variables costly collected by OBSERVATION Kinds of Quantitative does not consider the cause and effect Research This research design is based on pairs of measures or scores of a single sample. Descriptive Design It indicates the strengths of the relationship is used to describe a particular phenomenon by between two variables that embody the observing it as it occurs in nature. characteristics or performances of a group.

Survey Research Here, the independent variable is identified but not manipulated. this research design is intended to acquire information from people.
