Quarter 1 Week 2 Importance of Quantitative Research SLIDESMANIA.COM Practical Research II RECALL SLIDESMANIA.COM  What is a Quantitative Research? SLIDESMANIA.COM  A systematic and scientific investigation of data and their relationships. It is often associated with the word numerical. SLIDESMANIA.COM  Numerical means “of relating to numbers” or expressed by numbers, and would often answer questions like “how many” or “how much” or even “what rank” are the data being observed.

Discuss with your group and create at least 3 research topics of your chosen field of study B. What is the importance/rationale of your chosen topic? SLIDESMANIA.COM  Most inventions and innovations are products of quantitative studies. Before you can enjoy the uses and features of a smart phone, it took years of research to establish compliance to standards for interoperability, to find the most cost-effective raw materials, and to identify the sleekest and sturdiest design, the fastest data saving and SLIDESMANIA.COM  processing power, and the most marketable add-ons according to consumer needs. Indeed, mankind will dwell in the darkness of ignorance if not for the people who conducted their research before reading about it from books or manuals. SLIDESMANIA.COM  What do you think is the importance of quantitative research in our life today? How is quantitative research applicable across fields? SLIDESMANIA.COM  Research and Science When you become curious and doubtful about existing phenomena, you read books, search the internet or ask questions. Then you put all these pieces of information together to clarify your idea or add a new one. SLIDESMANIA.COM  This process of doing research is informal, because it does not strictly follow procedures and relies more on casual observation and opinions. For research to be more accurate and beneficial, science is embedded in its process. SLIDESMANIA.COM  Science is conceptualized as a procedural and systematic approach in gaining new knowledge by making thorough investigations and using controlled and precise methods. SLIDESMANIA.COM  Scientific Methods In Research Empirical Approach Knowledge is gained through direct observation and experimentation Observation Your awareness of your environment constitutes your ideas Question Knowledge comes from inquiries that are answerable Observation An educated guess to explain a phenomenon SLIDESMANIA.COM  Scientific Methods In Research Experiments The given hypothesis should assure testability in a crafted condition for the accuracy and reliability of results. Analyses For findings to be reliable, the data gathered are subjected for analysis through statistical methods. Conclusion Must be objective and supported by meticulous analysis of data Replication Doing the same study once again to a different set of participants to test the SLIDESMANIA.COM soundness of the obtained result  Goals of Research SLIDESMANIA.COM Description SLIDESMANIA.COM Prediction SLIDESMANIA.COM  Understanding / Explanation SLIDESMANIA.COM  Importance of Quantitative Research 1.

It is useful in testing results gained for qualitative research, arriving to a final answer/theory. 5. Results are often real and SLIDESMANIA.COM unbiased.  Importance of Quantitative Research Across Fields SLIDESMANIA.COM  The value of quantitative research to man’s quest to discover the unknown and improve underlying conditions is undeniable. Throughout history, quantitative research has paved the way to finding meaningful solutions to difficulties. For instance, the development of vaccines to strengthen our immunity against viruses causing highly communicable diseases like polio, influenza, chickenpox, and measles to name a few, underwent thorough experimental trials. You bet, scientists and medical experts all over the world today are working their best to fast track the development, testing and release of the vaccine for the Corona Virus Disease of 2019 (Covid-19) as the pandemic has critically affected the world economy, education, as well SLIDESMANIA.COM as physical and emotional well-being of people.  The findings of the quantitative study can influence leaders’ and law-makers’ decisions for crafting and implementing laws for the safety and welfare of the more significant majority. For example, a community with high cases of Covid-19 positive patients is mandated by law to be under Enhanced Community Quarantine where only the most essential businesses can operate. On the other hand, cities with less or zero case will be under General Community Quarantine where some businesses, public and private offices are already allowed to operate. SLIDESMANIA.COM  Using quantitative design helps us determine and better understand relationships between variables or phenomenon crucial to reducing the range of uncertainty because the mathematics (more of this in the last module) behind quantitative studies helps us make close estimates of the outcome (dependent variable) from a given condition/s (independent variable). Relationship between demand and supply, age and health, discipline and academic achievement, practice and winning at sports, depression and suicidal rates, algae population and Oxygen demand are just few examples of real-life applications of correlation studies in the past that we still apply today.

YES or NO Directions: Write YES if the statement describes the importance of a Quantitative Research, NO if not. 1. Researchers are often interested in how an understanding of a particular communication phenomenon might be generalized to a larger population. SLIDESMANIA.COM  Engagement 2. Experimental research designs may enhance the quality of medical education. 3. Research is just collecting facts or information with no clear purpose. SLIDESMANIA.COM  Engagement 4. When quantitative researchers explore questions of differences or questions of relationships, they do so in an attempt to uncover certain patterns of behavior. 5. People use social research to raise children, reduce crime, improve public health, sell products or just understand one’s life. SLIDESMANIA.COM
