Main ideas / lessons conveyed

  • The video explains how to identify research variables when creating a research project.
  • A variable is a characteristic/attribute of a person or object that is measurable or understandable.
  • There are two main types of research variables:
    • Independent variable: expresses the cause of a phenomenon.
    • Dependent variable: expresses the consequence/effect of that phenomenon.
  • When writing a research hypothesis, you must determine which variables it includes by looking at the general research question, since the hypothesis is a tentative answer to that question.
  • The example shows that:
    • A hypothesis can include one independent variable and one or multiple dependent variables.
    • The number and arrangement of dependent variables depends on the general research question.

Example used in the video (variable identification)

  • General research question: How to improve the reading comprehension of elementary school students in Puebla, Puebla, Mexico?

  • Hypothesis (tentative answer): Reading circles will allow us to improve the reading comprehension of elementary school students in Puebla, Puebla, Mexico.

  • Variable identification:

    • Independent variable (cause): Reading circles
    • Dependent variable (effect/consequence): Reading comprehension

Methodology / steps

  1. Step 1: Identify the variables in your research project.
  2. Step 2: Use the definition of variable: a measurable/understandable characteristic/attribute of something (person/object).
  3. Step 3: Classify variables into two categories:
    • Mark the independent variable as the cause.
    • Mark the dependent variable as the effect/consequence.
  4. Step 4: When forming your hypothesis, start from the general research question (the hypothesis should be the tentative answer).
  5. Step 5: Extract from the hypothesis the elements that represent:
    • the cause (independent variable),
    • and the result/effect (dependent variable).
  6. Step 6: If needed, allow for complexity:
    • You can have one independent variable and up to two or three dependent variables, depending on the general research question.
