Why is research important
Why is Research Important?

Provides new advanced systems and technology in food and agriculture (USDA-REE)

Need to feed the world

Research can “improve quantity, quality and sustainability” (DuPont Agriculture)


Types of research
Types of Research

Definition

  • Quantitative

    • Data includes measurements or counts

    • Standard scales

  • Qualitative

    • Descriptions



Types of variables
Types of Variables

Definition

  • Independent Variables

    • Altered or manipulated for the experiment

  • Dependent Variables

    • Respond during the experiment

  • Constants

    • Factors that are not changed during the experiment


Making your experiment v alid
Making your Experiment Valid

Definition

  • Control Group

    • Group Unchanged by researcher

    • Measure the influence of unanticipated

  • Multiple Trials


Hypothesis
Hypothesis

Definition

  • Prediction of the relationship between a independent and dependent variable in an experiment

  • Must use background research to form hypothesis

  • Accept or Reject after analyzing results


Forms of hypotheses
Forms of Hypotheses

If-Then

Non-directional


Hypothesis example
Hypothesis Example

Directional

If a plant is exposed to is green light, then the growth rate will increase.

Non-Directional

  • The growth rate of a plant will differ under green light.


Hypothesis example1
Hypothesis Example

Directional

If cattle are fed corn then the rate of gain will be greater than cattle fed grass.

Non-Directional

  • Rate of gain in cattle fed corn will differ from cattle fed grass.
