• What is the title of the module discussed in the study material?

  Characteristics of Experimental Research
• Why is conceptualizing and identifying topics important in research?


  It is essential for identifying the problem and the need to solve it.
• What does experimental research help determine?


  It helps in finding out the differences in the observed groups.
• What is the first step in every scientific process according to the material?

  To identify the problem and the need to solve it.
• What are the three objectives of the lesson on experimental research?

  1. Define experimental research; 2. Explain the purpose of experimental research; 3. Determine the elements/characteristics of experimental research.
• What is the significance of identifying the intended audience in research?


  It helps articulate the foundation of the study and its contribution to the community.
• How does the study suggest one can ensure a research topic is researchable?

  By determining if it can be solved through the scientific method and involves scientific manipulations and control.
• What was Gerald tasked to design an experiment about?


  How to improve the growth of tomato plants using different types of soil mixtures.
• What was the main issue with Gerald's first experiment setup?

  He did not use different types of soil for the three plots of tomatoes.
• What should Gerald do to improve his experiment after receiving feedback?

  Use different types of soil in each plot for his tomato plants.
• What did Gerald's teacher mean by lacking a basis of comparison?

  He needed a control group to compare the effects of different soil mixtures.
• How can Gerald improve his experiment setups according to the teacher's feedback?


  By including a control group composed of pure loam soil.
• What factors did Gerald realize could affect the growth of tomato plants?

  Sunlight and water.
• What can Gerald do to ensure sunlight and water do not affect his experiment results?

  Keep sunlight and water constant across all treatment groups.
• Why might the results of Gerald's third attempt be valid for analysis?

  Because he included a control group and minimized external factors.
• What trait did the study suggest is important for researchers, as demonstrated by Gerald?

  Perseverance in continuing the study despite challenges.
• What is experimental research defined as in the material?

  Experiments enable us to observe the effects of a certain variable under controlled conditions.
• What distinguishes experimental research from other types of research?

  It strictly adheres to the scientific method of solving a problem.
• What are the independent and dependent variables in Francis's study on pechay plants?

  Independent variable: varied amount of water; Dependent variable: growth of pechay plant.
• What is the manipulated variable in Gerald's experiment?

  The different types of soil used for the tomato plants.
• Why is it important to have at least one independent variable in experimental research?

  To manipulate and observe its effects on the dependent variable.
• What is the purpose of experimental research?

  To establish a direct relationship or cause-and-effect between two variables.
• What are the three major characteristics of experimental research?

  Manipulation, control, and randomization.
• Why is control important in experimental research?

  To prevent external factors from influencing the outcome of the study.
• How does randomization contribute to experimental research?

  It ensures that subjects have equal chances of being assigned to different treatments, avoiding bias.
• What is the significance of manipulating treatment variables in experimental research?


  It helps establish a cause-and-effect relationship between the manipulated and observed variables.
• In which part of Gerald's experiment can he apply randomization?

  In the selection of tomato plants for each plot to ensure they are similar at the start of the study.
• What are the steps in conducting experimental research?

  1. Identifying and stating the problem

  2. Stating a hypothesis

  3. Specifying the variables of the study

  4. Designing the experiment

  5. Setting up the control of the experiment

  6. Manipulating the nature and extent of the treatment

  7. Measuring the effects of the treatment

  8. Analyzing the data from the control and treatment groups

  9. Stating a conclusion
• How can one determine if a study qualifies as experimental research?


  • It must involve manipulation of at least one independent variable.
  • It should have a control group for comparison.
  • It must minimize the influence of external factors.
  • It should establish a cause-and-effect relationship between variables.
• What are the applications of experimental research?

  • Natural sciences
  • Education
  • Business
  • Social sciences (e.g., psychology)
• What are the strengths and weaknesses of experimental research?

  Strengths:

  • Establishes cause-and-effect relationships
  • Controls for external variables
  • Allows for replication

  
  

  Weaknesses:

  • May not reflect real-world scenarios
  • Ethical concerns in manipulation
  • Can be time-consuming and costly
