PRACTICAL RESEARCH 2 QUANTITATIVE RESEARCH INTRODUCTION CARLO S. AGRADE INTRODUCTION QUANTITATIVE RESEARCH It uses scientifically collected and statistically analyzed data to investigate observable phenomena. CONTINUE www.reallygreatsite.com INTRODUCTION QUANTITATIVE RESEARCH A phenomenon is any existing or observable fact or situation that we want to unearth further or understand. CONTINUE www.reallygreatsite.com INTRODUCTION QUANTITATIVE RESEARCH It is scientific for the fact that it uses a scientific method in designing and collecting numerical data.

CONTINUE www.reallygreatsite.com Ingoude Company STATISTICAL ANALYSIS Pearson’s R T-Test Analysis of Variance (ANOVA) www.reallygreatsite.com INTRODUCTION QUANTITATIVE RESEARCH Data is analyzed statistically, it is imperative that the data obtained must be numerical and quantifiable, hence its name quantitative research. CONTINUE www.reallygreatsite.com Ingoude Company EXAMPLES: Student’s grades in different subjects number of hours of engagement in social media platforms of teens www.reallygreatsite.com Ingoude Company EXAMPLES: Percentage of consumers who prefer the color blue for soap packaging average daily Covid-19 patient recovery per region www.reallygreatsite.com INTRODUCTION QUANTITATIVE RESEARCH Some data on the other hand, are not directly countable and thus require conversion from non- numerical information into numerical information. CONTINUE www.reallygreatsite.com INTRODUCTION Likert Scale we can use to quantify data Example: 1= tastes very good, 2 = satisfactory, or 3 = undesirable. Numerical choices convert texts into numbers so the researcher can perform mathematical operations for faster, more accurate, and more objective analysis. CONTINUE www.reallygreatsite.com  QUANTITATIVE RESEARCH CHARACTERISTICS It is analogous to scientific or experimental thinking because you do not just identify problems but theorize, hypothesize, analyze, and infer as well. It is usually used in hard sciences like physics, chemistry, biology, and medicine.

CONTINUE www.reallygreatsite.com QUANTITATIVE Ingoude Company RESEARCH OBJECTIVE Data gathering and analysis of results are done accurately, objectively, and are unaffected by the researcher’s intuition and personal guesses. CONTINUE www.reallygreatsite.com QUANTITATIVE Ingoude Company RESEARCH VISUAL RESULT PRESENTATION Data is numerical, which makes presentation through graphs, charts, and tables possible and for better conveyance and interpretation. CONTINUE www.reallygreatsite.com QUANTITATIVE Ingoude Company RESEARCH FASTER DATA ANALYSIS The use of a statistical tools give way for a less time฀consuming data analysis. CONTINUE www.reallygreatsite.com QUANTITATIVE Ingoude Company 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. CONTINUE www.reallygreatsite.com QUANTITATIVE Ingoude Company RESEARCH FAST DATA COLLECTION Depending on the type of data needed, collection can be quick and easy. Quantitative research uses standardized research instruments that allow the researcher to collect data from a large sample size efficiently. CONTINUE www.reallygreatsite.com QUANTITATIVE Ingoude Company 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. CONTINUE www.reallygreatsite.com QUANTITATIVE Ingoude Company RESEARCH REPLICATION The Quantitative method can be repeated to verify findings enhancing its validity, free from false or immature conclusions.

There is no experimental manipulation and the researcher does not start with a hypothesis. www.reallygreatsite.com  KINDS OF QUANTITATIVE RESEARCH Example: “The Determination Of The Different Kinds Of Physical Activities And How Often High School Students Do It During The Quarantine Period.” It can answer what, where, when and how questions, but not why questions. www.reallygreatsite.com  KINDS OF QUANTITATIVE RESEARCH Correlational Design Identifies the relationship between variables. Data is collected by observation since it does not consider the cause and effect www.reallygreatsite.com  KINDS OF QUANTITATIVE RESEARCH Example: “The Relationship Between The Amount Of Physical Activity Done And Student Academic Achievement.” www.reallygreatsite.com  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”, means after the fact, looks at the possible causes of an already occurring phenomenon. www.reallygreatsite.com  KINDS OF QUANTITATIVE RESEARCH Example: “How Does The Parent’s Academic Achievement Affect The Children Obesity?” www.reallygreatsite.com  KINDS OF QUANTITATIVE RESEARCH Quasi-Experimental Design is used to establish the cause and effect relationship of variables. Has lesser validity due to the absence of random selection and assignment of subjects. The independent variable is identified but not manipulated. www.reallygreatsite.com  KINDS OF QUANTITATIVE RESEARCH Example: “The Effects Of Unemployment On Attitude Towards Following Safety Protocol In ECQ Declared Areas.” The group exposed to treatment (Experimental) is compared to the group unexposed to treatment (Control). www.reallygreatsite.com  KINDS OF QUANTITATIVE RESEARCH Experimental Design 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. www.reallygreatsite.com  KINDS OF QUANTITATIVE RESEARCH Example: “A Comparison Of The Effects Of Various Blended Learning To The Reading Comprehension Of Elementary Pupils.” www.reallygreatsite.com
