What is the purpose of personal protection equipment (PPE)? - Answer To protect/minimize one's exposure to hazards that can cause serious workplace injuries and illnesses If the fist three steps of the scientific method are defined as observation, question, hypothesis, the next three are: - Answer Experiment, predict, collect T/F. Observation is the formulation of a question to gain more information about a phenomenon - Answer False T/F. It is best to formulate a hypothesis after data has been collected. - Answer False. Contrast inductive and deductive reasoning. - Answer Both inductive and deductive reasoning are used to develop a valid conclusion. However, inductive reasoning moves from specific scenarios into a generalized conclusion, while deductive reasoning moves from generalized truths to a true and specific conclusion. Contrast the differences among independent, dependent, and standardized variables. - Answer IV is the thing you're changing/altering DV is the thing you're looking at/for Standardized variables are what you know/what you expect to happen Define experimental group - Answer receives experimental treatment; independent variable is manipulated Define control group - Answer The IV is being eliminated or set to a standard value; no treatment Define positive control. - Answer Does not receive any experimental treatment; it will give an expected result; ensures an Define negative control. - Answer Doesn't give a result, and no result would be logically expected It would be reasonable to make predictions regarding which of the following (select all that apply): - Answer Negative control, positive control, hypothesis and/or outcome of dependent variable, null hypothesis Identify each as qualitative or quantitative data: 1. 42 meters 2. 2cc 3. Pain 4. Mean, median, and mode 5. Personal opinion - Answer 1. Quantitative 2. Quantitative 3. Qualitative 4. Quantitative 5. Qualitative What are the 4 components of data analysis? - Answer Summarize raw data, relationships, interpreting results, and reporting sources of errors In the United States, measurements pertaining to medical sciences are recorded and reported using: - Answer metric units A baby is born and the doctor pronounces the weight as 7 pounds 0 ounces. Using the metric system, how will this value appear in the infant's medical chart? - Answer 1 lbs = 2.2kg 7/2.2 = 3.18kg Tare functions are unreliable, and it is more accurate to mass the container alone, add the sample and then subtract the difference. T/F. - Answer False The graduated pipette is useful for: - Answer Transferring liquid from one beaker to another Disposable tips are characteristics to which type of pipette? - Answer Micropipette T/F. The majority of the world uses the metric system to quantify measurements. - Answer True T/F. The United States uses the SI system when recording and reporting health science data. - Answer False Provide the base unit for METRIC measurements in each of the following. 1. Length 2. Volume 3. Mass 4. Temperature - Answer 1. Meter 2. liter 3. gram 4. Celsius The unaided human eye can detect objects as small as: - Answer 0.1mm A light microscope has an eye piece magnification of 10X, and the objective lens is set to 30X. What is the total magnification? - Answer 300X What three parameters are vital to microscopy? - Answer 1. Magnification
