Biomedical Science Unit 1 Flashcards
Biomedical Science
the application of the principles of the natural sciences, especially biology and physiology, to clinical medicine
Control Group
the group in an experiment where the independent variable being tested is not applied so that it may serve as a standard for comparison against the experimental group where the independent variable is applied
Dependent Variable
the measurable effect, outcome, or response in which the research is interested
Experiment
a research study conducted to determine the effect that one variable has upon another variable
reliable experiment
experiment in which another researcher can perform the exact same experiment and generate similar results
valid experiment
experiment in which the results accurately describe the real world
Forensic Science
the application of scientific knowledge to questions of civil and criminal law
Hypothesis
clear prediction of the anticipated results of an experiment
Independent Variable
the variable that is varied or manipulated by the researcher
Negative Control
-control group where conditions produce a negative outcome-negative control groups help identify outside influences which may be present that were not accounted for when the procedure was created
Personal Protective Equipment
specialized clothing or equipment, worn by an employee for protection against infectious materials (as defined by OSHA)
Positive Control
group expected to have a positive result, allowing the researcher to show that the experimental set up was capable of producing results
rigor mortis
the stiffening of the muscles that occurs shortly after death
ambient
relating to the immediate surroundings
Glaister Equation
98.4 - measured temperature / 1.5
Steps of Experimental Design
1. Identify the problem or question2. Predict a solution to the problem or an answer to the question3. Design an experiment to test your hypothesis4. Carry out the experiment5. analyze the data and observations6. state the conclusion/summary paragraph
Identify the problem
-state the question you are trying to answer (should be specific and measurable)
Form a hypothesis
-clear prediction of the anticipated results-indicates independent and dependent variables
Design the procedure
step by step detail for how to perform the experiment
